Sidestep with an expander
The easiest way to understand what this exercise looks like is to imagine a zombie walking from side to side. It looks funny, but your buttocks will “burn” in a matter of seconds.
How to do this exercise:
Stretch the shock absorber around your ankles. Make sure there is enough tension even when your feet are shoulder-width apart. Keeping your legs straight, step to the right (stretching your right buttock) and gently pull your left leg up. Continue walking to the right for the required number of repetitions (or a certain distance), then to the left.
