Muscles worked
Setup
- Place a step on the floor and stand with your non-working foot firmly on the center of the step.
- Place a medicine ball on the floor to your side and rest the arch of your working foot on top of it.
- Keep your standing leg slightly bent and your torso upright, placing your hands on your hips for balance.
How to do it
- Inhale and slowly roll the ball away from your body by extending your working leg out to the side in a controlled manner.
- Exhale and engage your inner thigh muscles to pull the ball back toward the step until your legs are back to the starting width.
- Maintain a steady 2-second tempo for both the outward and inward phases of the movement.
- Complete the full set on one leg before switching to the opposite side.
Form checklist
- Keep your torso upright and avoid leaning toward the rolling leg.
- Ensure the standing knee remains stable and aligned over the toes.
- Initiate the pull from the hip and inner thigh rather than just the foot.
- Maintain a slight bend in the rolling leg to avoid locking the knee joint.
Pro tips
- Press down firmly into the medicine ball as you pull it back toward your midline to increase adductor recruitment.
- Focus on a 'scissoring' sensation between your thighs to maximize the mind-muscle connection with the adductors.
Make it harder
- Increase the range of motion by rolling the ball further away, ensuring you can still pull it back with proper form.
- Hold a light weight at chest height in a goblet position to further challenge your core and balance.
