Setup
- Place your hands shoulder-width apart on the long edge of a flat bench.
- Step your feet back until your body forms a straight line from your head to your heels.
- Position your shoulders directly over your wrists and engage your core.
How to do it
- Drive one knee toward the bench, exhaling as you pull it in toward your chest.
- Inhale as you step that foot back to the starting position.
- Immediately repeat with the opposite leg, alternating sides at a steady, rhythmic pace.
- Maintain a controlled tempo, focusing on keeping the hips level throughout the movement.
Form checklist
- Keep your back flat and avoid letting your hips sag toward the floor.
- Ensure your weight stays over your hands, not pushed back into your heels.
- Keep your gaze slightly ahead of the bench to maintain a neutral spine.
- Avoid bouncing your hips up and down as you switch legs.
Pro tips
- Think about 'crunching' your abs every time a knee comes forward to maximize lower abdominal recruitment.
- Press firmly into the bench to keep your shoulder blades stable and prevent your chest from sinking.
Make it harder
- Increase the speed to a 'sprint' pace to elevate the heart rate and cardiovascular demand.
- Drive your knee toward the opposite elbow (cross-body) to increase oblique activation.
