Start in a high plank position with your hands close together under your chest, forming a diamond shape with your thumbs and index fingers. Keep your body in a straight line from head to heels. Lower your chest toward your hands by bending your elbows, keeping them close to your body. Push back up to the starting position while engaging your core and maintaining proper alignment throughout the movement.
The diamond push up is the hardest common push up and the best bodyweight triceps builder: the narrow hand position keeps the elbows tracking along the ribs and shifts the work from the chest to the triceps and the inner chest. Program 3 to 4 sets close to failure on push days, either as a finisher after pressing or as the main triceps work when training without equipment. For most lifters that means somewhere between 8 and 25 reps per set, and the set ends when the hips sag or the elbows flare, not when the count gets impressive.
Progression runs in both directions. Too hard: do them from the knees, or with hands on a bench, keeping the same diamond and body line. Too easy: elevate the feet, slow the descent to 3 seconds, or add load with a weight plate on the upper back or a loaded backpack, treating 5 kg jumps like any other lift. If the wrists complain about the turned-in position, widen the diamond a few centimeters or do them on push up handles.
They are nearly the same exercise; the diamond is simply the narrowest version. If the full diamond bothers your wrists or elbows, hands at shoulder width with elbows tucked delivers almost identical triceps work with friendlier joints.
The narrow, turned-in hand position puts the wrists at an aggressive angle under most of your bodyweight. Widen the hands slightly, grip the floor hard, or use handles or dumbbells to keep the wrists neutral.
Stop chasing reps and start loading: feet elevated, a plate on the back, or a band across the shoulders. High-rep endurance sets stop building muscle long before they stop burning.
