Place your left foot in the center of the Bosu with your right foot parallel to your left on the floor. Bend down into a squat position, clasping your hands in front of you for balance.
In one quick motion, jump sideways to your left, over the Bosu, so your right foot replaces your left in the center of the Bosu. Your left foot should be parallel to your right but on the floor. Keep your body low in a squat as you plant your foot on the ground. Jump back over the Bosu, returning to the starting position. This completes one rep.
