Muscles worked

Primary

  • Calves

Secondary

  • Glutes
  • Hamstrings
  • Quadriceps

Equipment

  • Body weight

Setup

  1. Stand tall with your feet hip-width apart on a flat, level surface.
  2. Place your hands on a wall or sturdy piece of furniture at waist height for balance.
  3. Distribute your weight evenly across the balls of both feet with your toes pointing forward.

How to do it

  1. Exhale as you push through the balls of your feet to lift your heels as high as possible.
  2. Pause at the top for one second, focusing on a hard contraction in the calf muscles.
  3. Inhale as you slowly lower your heels back to the floor under total control.
  4. Maintain a controlled tempo of 2 seconds up, a 1-second pause, and 2 seconds down.

Form checklist

  • Keep your knees straight but not locked out to focus the tension on the gastrocnemius.
  • Move vertically toward the ceiling rather than leaning forward into the wall.
  • Ensure your weight stays centered over the first and second toes to avoid ankles rolling outward.
  • Keep your core braced and your shoulders back to maintain an upright posture.

Pro tips

  • To maximize muscle fiber recruitment, imagine you are trying to push the floor away from you as hard as possible.
  • Focus on the 'peak contraction' at the top; the higher you lift your heels, the more the calf muscles shorten and engage.

Make it harder

  • Perform the exercise unilaterally (one leg at a time) to double the resistance on the working calf.
  • Perform the movement with your heels hanging off the edge of a step to increase the range of motion and add a weighted stretch.
