High Knees

How to do it

1. Stand tall with your feet hip width apart, chest up and core engaged.
2. Drive one knee up toward your chest until your thigh is at least parallel to the floor, pumping the opposite arm as if sprinting.
3. Quickly switch legs, landing lightly on the ball of your foot as the other knee drives up.
4. Continue alternating legs at a fast running cadence, staying on the balls of your feet and keeping your torso upright.
5. Maintain the rhythm for the desired amount of time.
