Setup
- Stand with your feet shoulder-width apart and toes pointed slightly outward.
- Engage your core and maintain a neutral spine with your hands held at your chest or extended in front for balance.
- Lower your hips back and down into a squat until your thighs are parallel to the floor, as if sitting in an invisible chair.
How to do it
- Hold the bottom of the squat position statically, ensuring your weight is centered.
- Exhale as you drive through the balls of your feet to lift your heels as high as possible off the floor.
- Pause for a split second at the peak of the calf raise, squeezing the gastrocnemius.
- Inhale and slowly lower your heels back to the floor while maintaining the exact same squat depth and hip height.
Form checklist
- Keep your hips at a constant height; do not let them rise as you lift your heels.
- Ensure your knees stay tracked over your toes and do not cave inward.
- Maintain a proud chest and flat back throughout the entire set.
- Distribute weight evenly across the balls of your feet during the rock to avoid rolling the ankles.
Pro tips
- Focus on driving through the big toe during the heel raise to maximize calf activation and improve arch strength.
- Imagine there is a low ceiling just above your head to force your quads to stay under constant isometric tension.
Make it harder
- Pulse the squat slightly (1-2 inches) while simultaneously performing the calf rock to increase the metabolic demand.
- Hold a light weight in a goblet position to shift the center of gravity and further challenge the core and quads.
