Muscles worked
Setup
- Stand tall with your feet hip-width apart on a flat, level surface.
- Place your hands on a wall or sturdy piece of furniture at waist height for balance.
- Distribute your weight evenly across the balls of both feet with your toes pointing forward.
How to do it
- Exhale as you push through the balls of your feet to lift your heels as high as possible.
- Pause at the top for one second, focusing on a hard contraction in the calf muscles.
- Inhale as you slowly lower your heels back to the floor under total control.
- 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.
