Setup
- Sit upright on the edge of a sturdy chair or flat bench with your back straight and core engaged.
- Extend one leg forward with your heel resting on the floor and your toes pointed upward.
- Plant the opposite foot firmly on the ground for stability and grip the sides of the chair for support.
How to do it
- Press your heel firmly into the floor and pull it back toward the chair by flexing your knee.
- Exhale as you pull, maintaining constant downward pressure to create resistance against the floor.
- Squeeze your hamstring hard at the point of maximum knee flexion.
- Inhale and slowly slide your heel back to the starting position using a 3-second controlled tempo.
Form checklist
- Keep your torso stationary; do not lean forward or backward to assist the movement.
- Ensure the heel stays in contact with the floor throughout the entire rep.
- Focus on pulling with the back of the thigh rather than pushing with the toes.
- Keep your hips level and glued to the chair seat.
Pro tips
- To maximize activation, imagine you are trying to scrape something off the bottom of your shoe as you pull back.
- Perform this on a carpeted surface for more friction, or use a towel on a hard floor to focus on eccentric control.
Make it harder
- Add a 3-second isometric hold at the peak of the contraction (when the heel is closest to the chair).
- Loop a resistance band around your ankle and a stationary object in front of you to add external load.
