Full body conditioning

In this challenge we will complement our daily routines with flexibility work.

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.
