Muscles worked
Setup
- Stand tall with your feet shoulder-width apart and a slight bend in your knees for stability.
- Extend your arms out to your sides at shoulder height, keeping your palms facing forward.
- Engage your core and pull your shoulder blades down and back to stabilize your scapula.
How to do it
- Bring your arms forward until they cross in front of your chest, keeping your arms straight with a very slight 'soft' bend in the elbows.
- Perform small, rapid 'pulses' by moving your hands 4-6 inches apart and then crossing them back over each other.
- Alternate which hand crosses on top (left over right, then right over left) with every pulse.
- Maintain a fast, rhythmic tempo while breathing steadily; do not hold your breath.
Form checklist
- Keep your arms at shoulder height throughout the entire set.
- Maintain a proud, lifted chest to ensure the pectorals are doing the work.
- Avoid shrugging your shoulders toward your ears.
- Keep the movement small and controlled to maintain constant tension on the chest.
Pro tips
- Focus on the mind-muscle connection by imagining you are trying to squeeze your biceps against the sides of your chest.
- Maintain a slight 'hollow body' position in your torso to prevent your lower back from arching as you fatigue.
Make it harder
- Slow down the tempo to a 'slow-motion' pulse to increase time under tension.
- Perform the pulses at the end of a set of push-ups as a mechanical drop-set finisher.
