High knees

Stand tall, as if jogging in place. Arms bent, hands loose.

High knees
  1. 1Drive one knee toward hip height, then switch.
  2. 2Land on the ball of the foot, under the hips.
  3. 3Stay tall. Don't fold forward just to meet the knee.

Easy to miss: Leaning back, or barely lifting the feet off the floor.

Muscles

Copper on the figure is a prime mover. The softer tone helps.
