HOW: In a standing position, hinge forward at the hips and shift your weight to one leg. Kick the other leg straight back and raise your arms up straight overhead at the same time. When you are forward as much as you can tolerate, rotate your body towards the leg you are balancing on. Return to the starting position and repeat for the prescribed amount of reps.
FEEL: You should feel your hamstring, glute, and core muscles working.
COMPENSATION: Keep your back straight, even as you twist. Don’t slouch. Kick straight back with your leg.
