Side Hop Ski

  • Intermediate

  • Lower legs
  • Upper legs

This dynamic lateral movement builds explosive power and agility while challenging the glutes, quads, and core for improved athletic stability. It mimics a skiing motion to enhance lateral force production and cardiovascular endurance.

  • Glutes
  • Quadriceps

  • Hamstrings
  • Hip flexors

Equipment

  • Body weight

Setup

  1. Stand with feet hip-width apart, knees slightly bent, and core engaged.
  2. Position your arms at your sides, ready to swing for momentum.
  3. Shift your weight onto your right leg, preparing to push off laterally.

How to do it

  1. Exhale and push off your right foot to jump sideways to the left, landing softly on your left foot.
  2. Inhale as you land with a slight knee bend, sweeping your right leg behind your left ankle without touching the floor.
  3. Swing your arms across your body in a rhythmic 'skating' motion to maintain balance and momentum.
  4. Immediately push off the left foot to jump back to the right, alternating sides continuously.

Form checklist

  • Keep your chest lifted and avoid rounding your lower back.
  • Land softly on the mid-foot, absorbing the impact through your hip and glute.
  • Ensure your landing knee stays aligned with your toes and doesn't cave inward.
  • Maintain a rhythmic, athletic pace without sacrificing landing stability.

Pro tips

  • Focus on the 'stick'—pause for a fraction of a second on the landing to maximize glute medius activation and balance.
  • Drive your arms aggressively across your torso to increase oblique engagement and rotational power.

Make it harder

  • Increase the lateral distance of each jump to maximize power output and eccentric control.
  • Reach down to touch the floor with the opposite hand on every landing to increase the squat depth and core demand.
