Setup
- Place your hands shoulder-width apart on the edge of a stable stepbox or bench.
- Step your feet back into a high plank position, forming a straight line from your head to your heels.
- Position your shoulders directly over your wrists to ensure proper joint stacking.
How to do it
- Drive one knee toward your chest in a controlled motion, exhaling as you contract your abdominals.
- Return the foot to the starting position while inhaling, then immediately drive the opposite knee forward.
- Maintain a steady, rhythmic pace, alternating legs while keeping your hips level with your shoulders.
- Focus on a 1-1-1 tempo: one second in, one second back, with no pause between legs.
Form checklist
- Keep your back flat and avoid rounding your shoulders or arching your lower back.
- Ensure your hips do not bounce up and down as you switch legs.
- Maintain a neutral neck by looking at the top of the stepbox rather than your feet.
- Keep your core braced as if preparing for a punch throughout the entire set.
Pro tips
- Imagine pulling your belly button toward your spine to maximize deep transverse abdominis engagement.
- Keep your weight shifted forward over your hands rather than pushing back into your heels to keep the tension on the core.
Make it harder
- Increase the speed of the movement to a 'running' pace to elevate heart rate and metabolic demand.
- Perform a cross-body variation by driving your knee toward the opposite elbow to increase oblique recruitment.
