HOW: Start by looping a resistance band around your legs just above your knees. Grab onto a medball with both arms and hold against your body in a standing position with slight tension on the band and a small bend in your knees. From here, take a step to one direction, shifting your weight to that side as you rotate your upper body as far as you can to that side all while looking down at the ground. Repeat on the other side alternating from one side to the other for the prescribed amount of reps.
FEEL: You should feel your core and hip muscles working to rotate the upper half and hold your body mostly on the leg you step to.
COMPENSATION: Don’t lean forwards or backwards, maintain a stable position as you go from side to side.
