Equipment

  • Body weight

Setup

  1. Stand upright with feet hip-width apart, placing one hand on a wall or sturdy surface for balance support.
  2. Lift one foot off the ground, bending the knee slightly so the foot is suspended behind you.
  3. Align your standing foot straight forward with your weight distributed evenly across the ball of the foot.

How to do it

  1. Exhale as you push through the ball of your foot to raise your heel as high as possible, squeezing the calf at the top.
  2. Inhale as you slowly lower your heel back to the floor with a controlled 2-second tempo.
  3. Once the heel touches, continue the motion by rocking back onto your heel and lifting your toes as high as possible toward your shin.
  4. Return to the neutral starting position and immediately begin the next repetition without resting.

Form checklist

  • Keep the standing leg's knee straight but not locked out to maintain tension on the gastrocnemius.
  • Avoid using the wall to push yourself upward; use it only for light balance support.
  • Ensure the ankle does not roll outward during the heel raise phase.
  • Maintain an upright torso and avoid leaning forward to gain momentum.

Pro tips

  • Pause for one full second at the peak of the calf raise to maximize muscle fiber recruitment.
  • Focus on 'pulling' your toes toward your kneecap during the rocking phase to actively engage the tibialis anterior on the front of the shin.

Make it harder

  • Perform the exercise without holding onto a wall to significantly increase the demand on your core and ankle stabilizers.
  • Hold a dumbbell in the hand on the same side as the working leg to add external resistance.
