In this challenge we will complement our daily routines with flexibility work. I recommend you rest at least 10 or 15 minutes after your normal routine and then do the flexibility work, or even do it later on the day. We will focus on improving the range of motion in our shoulders, legs, wrists and our entire posterior chain, which will help us improve in the vast majority of tricks and difficult calisthenics exercises. Recommended for both beginners and advanced. Finally, I recommend you put take 15 to 20 second-long rests at most to do it quickly.
