What's new in Calisteniapp v25.8.0

The pistol squat, or single-leg squat, is probably the most complete exercise for training your legs in calisthenics. Unlike a conventional squat, here you don't just need strength to lift your entire bodyweight, but also balance, mobility, and coordination to maintain good technique throughout the full range of motion.

In this article you'll learn which muscles the pistol squat works, what requirements you need to meet before training it, how to perform correct technique, the best progressions to get it from scratch, the most common mistakes, and how to improve the mobility needed to execute this exercise safely and efficiently.

The pistol squat is a deep single-leg squat, keeping the other leg extended in front of you and off the ground.

The pistol squat is an advanced bodyweight exercise, since it requires several physical capabilities:

Leg strength to lift your entire bodyweight.

Flexibility and mobility in the lower body joints to execute the exercise correctly.

Balance to keep your center of gravity over a reduced base of support.

Coordination to move each part of your body correctly and simultaneously.

Even though the pistol squat is a single-leg squat, that doesn't mean the other leg is just relaxed and doing nothing. In fact, it's quite the opposite. Some people fail at this exercise not because they lack strength in the squatting leg, but because they can't keep the other leg extended.

For this reason, we need to break down the muscles involved by leg.

Glutes and adductors: these muscles are responsible for hip extension during the exercise.

Quadriceps: this is the muscle responsible for knee extension, with the exception of the rectus femoris, which isn't very active during the squat.

Calves and soleus: these two muscles perform ankle plantar flexion during the squat.

Hip flexors: at the hip level, to keep the leg raised in front of you, the opposite movement to the other leg occurs, meaning hip flexion. Accordingly, the main muscles involved are the iliopsoas, the rectus femoris, the sartorius, and the pectineus.

Quadriceps: at the knee level, to keep the leg straight during the exercise, knee extension also occurs, with the difference that, in this case, it's held isometrically. So even though this leg isn't performing the squat, the quadriceps are still active to some degree.

As you can probably tell, the hamstrings aren't very active in the pistol squat. If you want to know why and learn the best exercises to strengthen them, check out the following blog article:

Prerequisites Before Attempting the Pistol Squat

The only requirement I consider essential before training the pistol squat is being able to perform at least 10 to 20 controlled deep squats, meaning your hips drop below your knees.

Most beginners can handle the progressions I recommend for this exercise, so there really isn't a long list of prerequisites to start practicing it.

That said, being able to do 10 to 20 deep squats is the bare minimum, because it means you have a base level of leg strength and can squat all the way down without any issues.

Another condition I consider very important is not having any knee injury or pain. The early progressions I lay out in this article are relatively simple, but if you experience any kind of joint pain even with those, it's best to stop and see a professional, whether that's a doctor or a physical therapist.

How to Do the Pistol Squat: Step-by-Step Technique

Unlike a conventional squat, where you spread your feet and rotate them slightly outward, in the pistol squat both feet should stay together and point straight ahead so you can execute the exercise correctly.

I also recommend raising both arms in front of you to create a slight counterbalance, which will help you keep your balance.

Once you're in position, you'll perform the squat on one leg. The knee should stay well aligned with the foot. At the same time, you'll raise the free leg in front of you; the deeper you go, the higher you'll need to lift it.

Again, unlike a conventional squat, where you try to keep your torso as upright as possible, in the pistol squat your torso will lean forward slightly. This is completely normal, though. Otherwise, you'd lose your balance and fall backward.

In the bottom position you should be in a deep squat, with your whole foot fully planted on the ground, the free leg fully extended, and your arms raised in front of you.

At first, it's normal for the free leg not to be fully extended. It's also normal for some people to hold it with their hands to keep it from touching the ground. Keep in mind, though, that the end goal is to be able to perform the exercise without any assistance and with the leg fully extended.

Finally, you just need to return to the starting position by driving up through the squatting leg while simultaneously lowering the free leg.

Progressions to Get the Pistol Squat From Scratch

The first progression on our list is the split squat.

This is the first exercise because it's basically a single-leg squat with assistance from the other leg. The goal is to start shifting a higher percentage of your bodyweight onto one leg.

To do this, step forward with one leg while keeping the other one back. Both legs should point forward, with the back foot resting on the toes. Lean your torso slightly forward and squat down in a vertical line.

The second progression is the reverse lunge.

This exercise is very similar to the previous one, with the difference that you start with both feet together. From there, you step backward and lower your body in one continuous motion, then return to the starting position in a single movement.

The third progression is the deficit reverse lunge. This means you'll perform the exercise standing on a low platform, whether that's a step or a low box.

The goal of this progression is to let you go deeper, increasing the range of motion and getting closer to that of the pistol squat.

From this point on, the goal is to start building strength using only one leg, without help from the other.

To do this, you'll use a medium-height platform, roughly knee height. You can use a tall step, a chair, or a medium box.

You'll place one foot on top of the platform and the other one close to it. Don't place the bottom foot too far away from the platform, or you won't be able to perform the exercise correctly. Then lean slightly forward and step up using only the strength of the leg that's on the platform.

A very common mistake is pushing off with the bottom foot to help yourself up. That's exactly why we start with a medium height.

To progress with this exercise, you'll increase the height of the platform or use taller and taller boxes, with the same goal of increasing range of motion.

The fifth progression is the box pistol squat.

At this point you should already have enough strength to perform a full single-leg squat. However, as I mentioned earlier, now you need to be able to do that squat while keeping the other leg raised.

That's exactly the goal of this exercise: letting you perform the pistol squat without having to lift the free leg as high.

Here you'll do the opposite of the previous exercise. To progress, you'll gradually lower the height of the platform or use lower and lower boxes. This way you'll progressively build the strength and hip mobility you need.

Once you've worked through each of the previous progressions, you'll be ready to perform your first pistol squat on the ground without any help or assistance.

A very common mistake during the pistol squat is that, as you go down, your heel lifts off the ground. This usually happens because you don't have good ankle mobility and, as a result, you have to compensate by raising your heel. In the next section I'll explain how to improve this.

As I mentioned earlier, it's normal not to be able to fully extend the free leg at first. That said, it shouldn't be too bent either, since this reflects limited hip mobility. Further down I'll show you how to improve it to fix this mistake.

Your whole body should be facing forward. The foot shouldn't rotate outward, and the knee shouldn't collapse inward. Otherwise, not only will you fail to apply force optimally, but you'll also increase the pressure on your joints, which can cause pain or even contribute to an injury.

How to Improve Ankle Mobility for the Pistol Squat

The pistol squat requires a good range of ankle dorsiflexion. Otherwise, this will be a major limiting factor when it comes to performing the exercise correctly.

One way to improve ankle mobility is by increasing the flexibility of the gastrocnemius and soleus. To do this, you can perform the following calf stretch.

This involves placing the leg you're going to stretch behind you, so the whole sole of the foot stays flat on the ground and your legs form a diagonal line. The idea is to feel a strong stretch in the back of your leg.

Another way to improve ankle mobility is through the same progressions used for the pistol squat. The goal is to perform each exercise mimicking the actual pistol squat technique as closely as possible. For example, when doing the reverse lunge, don't step too far back with your rear foot, since that will put your knee far above your ankle, whereas in the pistol squat the knee goes past the toes.

How to Improve Hip Mobility for the Pistol Squat

The pistol squat also requires you to be able to lift the free leg and keep it extended so it doesn't touch the ground.

On one hand, you need good flexibility in the muscles of the posterior chain. For this, I recommend the following stretch.

On the other hand, you need your hip flexors to have strength at the end range of the movement, meaning they need to be able to lift a straight leg with the hip fully flexed. For this, I recommend the following exercise: hanging leg raises with hip flexion.

While the ideal routine to learn the pistol squat will depend on each person's level and specific context, the following routine is a great option for most people.

3x6-10 Hanging leg raises with hip flexion

Getting the pistol squat doesn't just come down to having strong legs. Mobility, balance, and good technique also play a key role. If you train with the right progressions and stay consistent, sooner or later you'll be able to perform this exercise correctly and safely.

Pistol Squat: Technique, Progressions, and How to Get It From Scratch

If your goal is to build muscle mass, improve your calisthenics performance, and develop more strength, there comes a point where training hard simply isn't enough anymore. Your body needs energy to build new muscle tissue, recover from your workouts, and adapt to increasingly demanding training loads.

This is where the caloric surplus comes into play: eating more calories than you burn each day to give your body the resources it needs to build muscle.

However, a lot of people misunderstand this concept and think that building muscle means eating as much as possible. The reality is that an excessive calorie surplus usually translates into rapid body fat gain, which is especially counterproductive in a sport like calisthenics, where the strength-to-bodyweight ratio is key to performance.

In this article you'll learn what a caloric surplus is, how to calculate it correctly, and how to apply it to build muscle while minimizing fat gain, always keeping the focus on performance and progression in calisthenics.

When we talk about what a caloric surplus is, we're referring to a situation where you eat more calories than your body burns on a daily basis.

If your body needs 2,500 kcal to maintain its current weight and you eat 2,800 kcal, you're creating a surplus of 300 kcal per day.

That extra energy can be used for multiple purposes, but when combined with well-structured strength training and adequate protein intake, a significant portion of it goes toward building muscle tissue.

For this reason, a caloric surplus is the main nutritional mechanism for gaining muscle mass. Without enough energy, your body will struggle to maximize the adaptations from your training.

That said, it's important to understand that more calories don't automatically translate into more muscle. Your body's capacity to build muscle mass has a limit. When the surplus is too large, a big chunk of that extra energy ends up being stored as fat.

Difference between a caloric surplus and a caloric deficit

Energy balance can fall into three different scenarios:

Caloric deficit: you eat fewer calories than you burn. The main goal is usually losing body fat.

Maintenance: you eat roughly the same amount of calories you burn. Body weight tends to stay stable.

Caloric surplus: you eat more calories than you burn. The main goal is gaining muscle mass and supporting recovery.

We can look at this with a simple example:

While a deficit is typically used during fat-loss phases, a surplus is used when the priority is building muscle mass and improving performance. In calisthenics, strategically cycling through deficit, maintenance, and surplus phases can be a useful tool for optimizing both body composition and athletic performance.

How much of a caloric surplus you need to build muscle

One of the most common questions is how many calories to build muscle you actually need. The answer is that most people get better results with a moderate surplus.

The most common approach is adding 200 to 300 kcal per day on top of your total energy expenditure. This range usually provides enough energy to support muscle gain without excessively increasing fat accumulation.

TDEE (total daily energy expenditure): 2,600 kcal

Some people choose to add more than 500 kcal per day, thinking they'll grow faster that way. While this can speed up the rate of weight gain, it also noticeably increases the amount of fat gained along the way.

Because of this, an aggressive surplus is rarely the best option for calisthenics athletes. Gaining too much body weight can make exercises like pull-ups, dips, muscle ups, or advanced relative-strength progressions harder to perform.

The reality is that muscle grows at a limited rate. Eating way more than you need doesn't proportionally speed up muscle gain.

How to calculate your caloric surplus step by step

Step 1: Calculate your basal metabolic rate (BMR)

Your basal metabolic rate represents the energy your body needs to stay alive at rest.

One of the most widely used formulas is the Mifflin-St Jeor equation:

-MEN: BMR = (10 x weight) + (6.25 x height cm) - (5 x age) + 5

-WOMEN: BMR = (10 x weight) + (6.25 x height) - (5 x age) - 161

Step 2: Calculate your total daily energy expenditure (TDEE)

Now you need to multiply your basal metabolic rate by your activity level.

Once you've calculated your TDEE (total daily energy expenditure), simply add 200 to 300 kcal. Following the example above:

If after several weeks your weight isn't going up and your performance isn't improving either, you can add another 100-150 kcal per day.

On the other hand, if your weight is going up too fast and you're noticing excessive fat gain, it's a good idea to slightly reduce the surplus.

That's how to calculate a caloric surplus in a practical, realistic way.

Caloric surplus without gaining too much fat: how to pull it off if you train calisthenics

A lot of people are looking for a caloric surplus without gaining excess fat. While it's impossible to build muscle without gaining some body fat, it is possible to minimize it. To achieve this:

More isn't always better. A surplus of 200-300 kcal usually offers the best ratio between muscle gain and fat accumulation.

Scientific evidence shows that an intake of between 1.6 and 2.2 g of protein per kilogram of body weight supports muscle protein synthesis.

Training is the signal that tells your body where to put that extra energy. If there's no proper progression in pull-ups, dips, squats, push-ups, or advanced calisthenics exercises, some of those extra calories will end up stored as fat.

Weigh yourself weekly under similar conditions.

Larger gains usually point to a calorie excess.

Clean bulk vs dirty bulk: which one should you choose if you do calisthenics

Two concepts tend to come up in the world of muscle gain:

Progress may be somewhat slower, but it's usually the more sustainable option.

Excessive consumption of ultra-processed foods.

Discover what a caloric surplus is, how to calculate it correctly, and how to apply it if you train calisthenics to build muscle without piling on extra fat.

Caloric Surplus: What It Is, How to Calculate It, and How to Apply It If You Train Calisthenics

With the rise of calisthenics worldwide over the last two decades, many parks have been built around the world, so major cities increasingly have more of this type of equipment.

But this has also raised a question: What equipment should these parks have to fulfill their purpose correctly? How can someone make sure their park is well built and has everything needed to practice this sport satisfactorily, without wasting money?

In this article we'll cover all the details on this topic, so no doubt remains.

We consider a calisthenics park to be a space with bar structures for exercising, mainly using bodyweight. Its most characteristic elements, though not the only ones, are pull-up bars and parallel bars for dips.

Traditionally, these parks are outdoors and free to access, but they can also be found in indoor settings, private buildings, or gyms that charge a fee for their use. Most commonly, the bars are made of metal and the ground is rubber, artificial turf, sand, or another material that cushions falls, even if only slightly.

A very common situation that continually arises worldwide with calisthenics parks is that public entities want to build a calisthenics park but don't properly inform themselves about what this park should be like: what specific characteristics it should have and what equipment is correct, what the measurements are, the materials, etc.

Many times they hire companies that also don't know this information, so the parks they build are inadequate, poorly made, have shortcomings, have incorrect measurements, and don't allow optimal use for the people who want to train in them.

Why Is It So Important That the Park Be Designed and Installed Correctly?

If the park doesn't have the right characteristics, it can cause injuries when used or when performing exercises on facilities that aren't appropriate, and it may not allow the execution of certain specific exercises that are important.

It can also happen that the bars deteriorate quickly, move, come unscrewed, or don't adapt well to extreme temperatures, preventing training under those conditions.

One of the most frustrating mistakes is when the park includes an element originally designed for one function but installed in such a way that function can't be performed. For example, we find parallel bars that, although intended for dips, are placed at an incredibly high height. Other cases include elements designed for wheelchair users that don't actually allow them to use them, or pull-up bars that are too low or too high.

In these cases, the company responsible for installing the park has simply copied and pasted a design from a professional park, but failed on the height, the thickness of the bars, or another important element for its correct use.

Why do public entities bear a large responsibility in this regard? When a city council installs a calisthenics park without getting proper advice and without hiring a professional company that can create a correct park, it is committing negligence that can lead to the following outcomes:

Wasting public money on a structure that doesn't fulfill the intended function and doesn't satisfy the taxpayer's needs.

Causing injuries to the people who use it.

Failing to act with diligence, professionalism, and good practice.

Let's now build a step-by-step structure for how a park that is truly useful, fulfills the function it was designed for, and doesn't result in wasted money should be planned and installed:

Step 1: Define the Park's Size and Budget

The first thing would be to define roughly how much money you want to spend on this park and how much physical space is available for its installation.

This would be the first step so that, when contacting the company that will build it, they can generate a budget and design for it.

Step 2: Choose a Company Specialized in Calisthenics Parks

This is the step where the most important mistake is usually made.

Fortunately, there are now many companies worldwide that specialize in building calisthenics parks. However, city councils or public entities usually choose cheaper companies that aren't calisthenics specialists, but instead focus on installing playgrounds, foundries, and other structures. Therefore, they are much more prone to making design and installation errors.

This selection process is often carried out through a public tender, choosing the company that presents the cheapest budget and meets the requirements set by the city council. The trick for this process to work correctly is for the requirements requested by the city council or public entity to have a very high technical specificity, so that any company focused on playgrounds or foundries can't meet them, and only companies presenting a high-quality project specialized in calisthenics can do so.

Once the company is involved, it will be necessary to go into detail about the elements that will make up the park. Later on, we'll present a list of the main components and examples of what a park should include depending on its size, so that it fulfills the basic functions.

Fortunately, by having the guidance of a company specialized in calisthenics, much of the work is already done, since they know which structures to install for each given size and budget.

The ideal thing at this stage is to consult the design with local athletes who will use the park, to find out if they have any special needs or if they're missing any element that could be added or modified. This way, an agreement is reached between what the city council is willing to pay, what the specialized company proposes, and what the athletes who will use it want.

It's also important to define the type of ground for the park, since it varies depending on whether a firm surface, rubber, artificial turf, gravel, or sand is required. This decision depends on how the athletes will use it, the budget, the location, and the climate conditions, so it deserves careful attention.

At this step you need to be careful, since even when a company specialized in calisthenics is selected, sometimes the actual installation of the park is carried out by an external company or professionals hired by the city council or public entity, who aren't necessarily experts in calisthenics or as diligent as we would like.

Therefore, ideally someone should supervise that the installations are being placed correctly, that the bars are level, and that there are no errors in the installation. It's not the first time I've seen a park where, on the posts meant for bars, they install parallel bars, and on the posts meant for parallel bars, they install pull-up bars. So we end up with extremely tall parallel bars at over 2 m in height and pull-up bars just 1 m off the ground.

In my experience, it's important that both someone from the city council and some of the athletes who are going to use the park keep an eye on it periodically to make sure the installation is being carried out correctly. Because if errors aren't corrected at the time of installation, it can later be very difficult to correct them, or it can take a very long time.

Step 5: Maintenance and Changes to the Park

Once the park is installed, it's also advisable to review it periodically for maintenance, since some structures may wear out, move, or need repainting.

It may also happen that, based on how the park is being used, it's worth making some small changes, such as:

or changing the position of some other element.

All of this should happen based on feedback from park users and in constant contact with the city council or public entity responsible for it.

What Elements Can Be Installed in a Calisthenics Park

Let's look at a list of some of the most characteristic elements that can be installed in a calisthenics park.

Obviously, not all of them are included, since the possibilities are practically endless, but I consider these to be the most interesting for building as complete a park as possible.

It's worth noting that most of these elements, although mainly intended for a specific exercise, can be used for countless variations, exercises of all kinds, and adaptations, which is one of the main characteristics of calisthenics: being able to use a simple bar for so many different exercises.

The pull-up bar is usually at a height of between 1.90 m and 2.30 m and consists of two posts and a horizontal bar.

It's usually linked with other bars to form square or triangular structures, so that a single post can hold two bars and place them at different heights, adapting to the characteristics or needs of the users.

The thickness of the bar, like most of the bars we'll see below, has been set at a standard of 35 mm, considered optimal for most exercises.

This bar is designed for use in the freestyle calisthenics discipline, which requires ample space and needs to be clear in front, behind, and to the sides, so that dynamic and static-hold tricks can be performed.

It must be much wider than a conventional pull-up bar, exceeding 2 m in width.

It needs clear space around it, so that when performing dynamic tricks, the person doesn't hit any obstacle.

This pull-up bar allows a person in a wheelchair to lift themselves out of the chair on their own, holding onto the side posts, and perform pull-ups.

Therefore, it must be at a relatively low height; otherwise, the person wouldn't be able to grab onto it.

I've seen parks that have this type of bar placed at over 2.30 m in height, so that after getting up from the chair, the person would have to "climb" up the grips in order to hang, a nonsensical result caused by not understanding what's being installed.

Similar to a pull-up bar but at a height of approximately one meter to one meter thirty, so you can hang underneath it and perform Australian pull-ups.

It can also be used to do high incline push-ups, ideal for beginners.

The classic parallel bars. They should generally be at a height of about 1.50 m, with a spacing of between 55 and 65 cm. Parallel bars are usually thicker than pull-up bars, with a thickness of 50 mm.

This type of parallel bars has an opening and a ramp so that a person in a wheelchair can go inside, get up using the ramp, and perform dips on the parallel bars.

Again, the heights and spacing must be very carefully considered so that they are actually usable by a person in a wheelchair, since real disasters have been seen in this regard.

These parallel bars are usually used to practice handstands, planche, and can also be used to perform push-ups. They usually have the same thickness and spacing as the tall parallel bars.

A consecutive series of pull-up bars that can be used to move from one to the next or to perform pull-ups with a pronated grip, neutral grip, wide grip, etc.

A succession of bars in a vertical line, parallel to the ground, that allows us to perform ab exercises, stretches, flag, dragon flag, etc.

These are usually at three heights: one closer to the ground, one a bit higher (roughly knee height), and another at the height of the Australian pull-up bars (roughly hip height). This way, push-ups can be performed at different difficulty levels.

This element presents a certain amount of complexity, since to be usable it must offer adequate freedom of movement and resemble Olympic rings as closely as possible.

It must also have high anti-vandalism security, since they are very vulnerable to being broken, stolen, or cut by people.
