HOW: Keeping your hands on the wall for balance, hop on both legs. Don’t allow your knee to collapse in, most of the motion should be coming from your ankles. Think of yourself as a rubber band or a spring loaded coil. Be bouncy!
FEEL: You will feel the calf muscles working with this exercise.
COMPENSATION: Do not let your ankle “roll out”. You should feel even pressure between the inside and outside of the balls of your foot.
