Setup
- Place your hands shoulder-width apart on an elevated surface like a bench, bar, or sturdy table.
- Step your feet back until your body forms a straight line from head to heels in a high plank position.
- Engage your core and squeeze your glutes to create a rigid frame.
- Position your shoulders directly over your wrists to start.
How to do it
- Inhale and slowly bend your elbows to lower your forehead toward your hands, keeping your upper arms stationary.
- Lower yourself until your elbows are fully flexed, ensuring they stay tucked in and pointed forward.
- Exhale and push through your palms to extend your arms back to the starting position.
- Maintain a controlled 3-second lowering phase and a powerful 1-second push.
Form checklist
- Keep elbows tucked in and parallel; do not let them flare out to the sides.
- Maintain a perfectly straight spine; do not let your hips sag or your lower back arch.
- Ensure the movement occurs only at the elbow joint, not the shoulders.
- Keep your neck neutral by looking at the space between your hands.
Pro tips
- Think about 'pushing the world away' from you to maximize triceps recruitment at the top of the rep.
- Intentionally squeeze your triceps at full extension to achieve a peak contraction.
- The lower the surface you use, the more bodyweight you transfer to your arms, increasing the load.
Make it harder
- Perform the exercise on the floor from a full plank position to maximize the weight load on the triceps.
- Add a two-second pause at the bottom of the movement to eliminate momentum and increase time under tension.
