Diamond Push-Ups and Tricep Development

The diamond push-up — hands close together forming a diamond shape directly under the sternum — is the most effective bodyweight exercise for tricep isolation. Here's how it fits into a calisthenics program.

Muscle emphasis: by narrowing the hand position and keeping elbows tracking close to the body, the triceps take the majority of the push. The chest involvement decreases significantly compared to standard width push-ups.

Where they fit: as an accessory movement after main pushing work, or as a finisher for a pushing session. They're not a primary strength movement — too much direct tricep work can aggravate the elbow — but as supplemental volume they build the lockout strength that carries over to dips, handstand push-ups, and ring work.

Form: elbows track close to the torso throughout. The hands can be fingertip-touching or slightly apart. Don't let the elbows flare — that shifts the load to the shoulders.

Progression: standard diamond push-up → diamond push-up with feet elevated → diamond push-up with slow eccentric → weighted diamond push-up (book or plate on back).
