Touching your thumbs and index fingers into a diamond forces the elbows to track tight and the hands to sit under your sternum, making this the most triceps-dominant hand position in the family. It also concentrates stress on the wrists, so lifters who find it uncomfortable usually get similar work from the regular close grip push-up.

How to do the Diamond Push-Up

  1. Start in a high plank position with your hands close together, forming a diamond shape with your thumbs and index fingers.
  2. Keep your body in a straight line from head to toe, engaging your core and glutes.
  3. Lower your chest towards the diamond shape formed by your hands, keeping your elbows close to your body.
  4. Pause for a moment at the bottom, then push yourself back up to the starting position.
  5. Repeat for the desired number of repetitions.

Tip: Screw your hands into the floor as if turning the fingers outward to set the shoulders before each set.

Muscles worked

Primary

Triceps · Arms

The triceps finish the rep by locking the elbows, and they do more work the narrower your hands are.

Secondary

  • Pectorals — The chest drives the arms together as you push, and it is loaded most in the bottom half of the rep when the elbows are bent.
  • Delts — The front delts assist the chest, especially on decline variations where the feet are elevated.

Common mistakes

  • Hips sagging or piked — the body should stay a straight line from head to heels; squeeze the glutes and brace the abs before each rep.
  • Elbows flared to 90 degrees — flaring the arms out wide loads the shoulder joint; keep the elbows tucked to about 45 degrees from the torso.
  • Cutting the bottom short — chest should come to within a fist of the floor; if that means fewer reps, do fewer reps.
  • Head dropping first — the chin reaching for the floor makes it look like a rep when it is not; keep the head neutral and lead with the chest.

Where it fits in a workout

Push-ups work as a warm-up before bench press, as a finisher after chest work or as the main push exercise when training with no equipment. Superset them with inverted rows or a band pull-apart for balance.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
