Setup
- Sit on a chair or bench with your back straight and feet flat on the floor.
- Place a medicine ball on the floor directly in front of your right foot.
- Position the ball of your right foot on the top center of the medicine ball with your heel suspended.
How to do it
- Exhale and push the ball forward by extending your ankle into full plantarflexion, squeezing the calf muscle at the end of the range.
- Inhale and slowly roll the ball back toward your body, allowing your heel to drop toward the floor to feel a deep stretch in the calf.
- Maintain a controlled 2-0-2 tempo, ensuring the movement is fluid and driven entirely by the ankle.
Form checklist
- Keep your working knee tracking directly over your toes to avoid ankle collapse.
- Ensure the movement is isolated to the ankle joint rather than using the hip to push the ball.
- Keep your non-working foot firmly planted on the floor for stability.
Pro tips
- Press your foot firmly into the ball throughout the movement to increase the active tension on the calf muscles.
- Focus on the stretch at the 'back' of the movement to improve long-term ankle dorsiflexion and mobility.
Make it harder
- Perform the exercise while standing on one leg to add a significant balance and stability challenge to the calf.
- Place a dumbbell or weight plate on the thigh of the working leg to increase the resistance during the roll.
