Muscles worked

Primary

  • Calves
  • Deltoids

Secondary

  • Hamstrings
  • Hip flexors

Equipment

  • Body weight

Setup

  1. Place your hands shoulder-width apart on the long edge of a flat bench.
  2. Step your feet back until your body forms a straight line from your head to your heels.
  3. Position your shoulders directly over your wrists and engage your core.

How to do it

  1. Drive one knee toward the bench, exhaling as you pull it in toward your chest.
  2. Inhale as you step that foot back to the starting position.
  3. Immediately repeat with the opposite leg, alternating sides at a steady, rhythmic pace.
  4. 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.
