Place two chairs side by side with enough space for your torso to fit in the middle.
Place each hand on the back of each chair and perform the Australian pull-up movement.
Try to keep your back straight in relation to your thighs, avoiding letting your hips drop or rise too high.
The higher the chairs, the greater the difficulty of the exercise.
This exercise requires you to keep your arms at a 90-degree angle relative to your torso, thus working less on your back and more on the rear deltoid.
