Exercise guide

Side Shuttle

  • Intermediate
  • Compound
  • Timed hold
  • Lower legs
  • Upper legs

The side shuttle is a dynamic lateral movement that builds agility and lower body power while engaging the core for stability. It effectively targets the glutes, quads, and calves through explosive side-to-side transitions and constant tension.

Equipment

  • Body weight

Setup

  1. Stand with feet hip-width apart and knees slightly bent in an athletic stance.
  2. Clear a lateral path of 5-10 feet and lower your hips into a partial squat.
  3. Keep your chest up and hands held in front of your body for balance.

How to do it

  1. Push off your trailing foot to take quick, short lateral steps in one direction.
  2. Maintain the partial squat height throughout the movement without crossing your feet.
  3. Upon reaching the end of the path, tap the floor and immediately push off the outside foot to reverse direction.
  4. Breathe rhythmically, exhaling forcefully each time you change direction.

Form checklist

  • Keep your feet parallel and avoid clicking your heels or crossing your legs.
  • Maintain a flat back and avoid rounding your shoulders when reaching for the floor.
  • Stay on the balls of your feet to ensure quick, reactive transitions.
  • Ensure your knees stay tracked over your toes during the lateral push.

Pro tips

  • Imagine there is a low ceiling above you to force yourself to stay low, keeping constant tension on the quads and glutes.
  • Focus on the 'plant and go' mechanic—minimize the time spent at the turnaround point to improve explosive power.

Make it harder

  • Hold a light medicine ball at chest height to increase the demand on your core and stabilizers.
  • Increase the speed and decrease the shuffle distance to focus on rapid acceleration and deceleration.
