  • Reps are per leg in each direction
  • Keep core locked; legs together
  • Bend knees to absorb force
FULL DIRECTIONS +
  1. Stand tall, balanced on one leg with your arms bent at your sides. Lock your core, pull your shoulders back, and relax your neck.
  2. On one foot, hop to one side. Land softly, with your knee bent to absorb force.
  3. Upon landing, immediately jump back in the other direction. Continue alternating until all reps are complete. Reps are prescribed per leg in each direction, so 6 reps means 12 total hops side-to-side on one leg. Then repeat on the opposite leg.

Ice Skater

BW × 6 reps each
ACTUAL MOVEMENT DEMO

KEY COACHING CUES

  • Control the landing before jumping again
  • Load all weight on the outside of one foot
  • Gain ground vertically and laterally on each jump
FULL DIRECTIONS +
  1. Stand tall with feet shoulder-width apart. Load the hips by pushing the butt back slightly, then bring one leg back behind the body to fully load the hip of the standing leg. Prepare to jump as far as you can in the opposite direction of the standing leg. The opposite foot may or may not touch the ground for balance.
  2. Keeping the core tight, explosively jump laterally as far as possible, landing softly on the opposite leg while swinging the other leg behind you for balance. Control the landing before beginning the next jump.
  3. After landing, jump back explosively to your starting point, minimizing your time on the ground and trying to jump as far and high as possible.
  4. Do not allow the spine to bend and the back to round. Keep your weight in the outside of the jumping foot to utilize the glutes and maximize jumping distance.
