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 object at chest height for balance if needed.
  3. Distribute your weight evenly across the balls of both feet, ensuring your ankles are neutral.

How to do it

  1. Exhale as you press through the balls of your feet to lift your heels as high as possible.
  2. Hold this peak contracted position for the target duration, keeping your calves under constant tension.
  3. Maintain steady, rhythmic breathing throughout the hold; do not hold your breath.
  4. Inhale as you slowly lower your heels back to the floor with control once the time is up.

Form checklist

  • Keep your knees straight but not locked out to prioritize the gastrocnemius.
  • Ensure your weight is centered over the big toe and second toe to prevent the ankles from rolling outward.
  • Maintain a tall, upright posture with your core engaged and shoulders back.
  • Keep the heels at their maximum height for the entire duration of the hold.

Pro tips

  • Focus on 'pushing the floor away' to maximize the mind-muscle connection and peak contraction.
  • If you feel the tension shifting to your toes, shift your weight slightly back toward the balls of the feet while maintaining heel height.

Make it harder

  • Perform the hold on a single leg to double the resistance and increase the stability demand.
  • Hold the position while standing on the edge of a step to increase the balance challenge and prepare for a greater range of motion.
