Setup
- Stand with your back flat against a sturdy wall and feet shoulder-width apart.
- Walk your feet forward approximately 2 feet from the wall.
- Slide your back down the wall until your thighs are parallel to the floor, creating a 90-degree angle at the knees.
- Ensure your ankles are positioned directly underneath your knees.
How to do it
- While holding the seated position, lift your right heel as high as possible by pressing through the ball of your foot.
- Lower the right heel back to the floor with control and immediately lift the left heel.
- Continue alternating heel taps at a steady, rhythmic pace (approx. 1 second per tap).
- Maintain a steady breathing pattern, exhaling on each heel lift and inhaling as you switch sides.
Form checklist
- Keep your entire back and head pressed firmly against the wall at all times.
- Ensure your knees do not cave inward; keep them tracked over your mid-foot.
- Do not rest your hands on your thighs; keep them at your sides or crossed over your chest.
- Maintain the 90-degree knee angle without letting your hips slide upward.
Pro tips
- Focus on pressing the small of your back into the wall to engage your core and prevent lower back arching.
- Pause for a split second at the top of each heel lift to maximize the peak contraction in the calf muscle.
Make it harder
- Hold a dumbbell or a weighted plate on your lap to increase the resistance on the quads and calves.
- Extend your arms straight out in front of you at shoulder height to increase the demand on your core and balance.
