HOW: Begin by placing a BOSU ball on the ground with the ball side down. Center one foot in the middle of the BOSU. Slightly bend your knee and hinge forward at the hips finding your balance. From here, straighten the other leg out and reach forward with it tapping the floor in front and then tapping the floor behind you all while maintaining this single leg squat position.
FEEL: You should feel the muscles in your glutes, thigh, and lower leg working.
COMPENSATION: Don’t arch your back, keep it flat. Keep your knee bent in a squat position.
