Step-by-step form

  1. Setting up

    Set up in a high plank with the hands under the sternum, thumbs and index fingers close enough to form a diamond/triangle shape. Keep feet about hip-width apart, legs straight but not aggressively locked, and the body in one line from head to heels. Keep shoulders away from the ears and lightly push the floor away so the shoulder blades start active and controlled.

  2. The movement

    Lower the chest toward the hands under control while keeping the elbows close to the torso. At the bottom, the chest approaches the hands; pause briefly without letting the hips sag or the head reach forward. Press the floor away, extend the elbows strongly, and return to the starting plank line. The torso should move as one unit on every rep, not as a separate arch through the lower back.

  3. What stays in line

    Elbows should stay close to the torso at roughly 20-45 degrees; flaring them wide reduces the triceps emphasis and can pinch the front of the shoulder. If the wrists feel sharply bent, the hands are probably too narrow; keep the diamond shape while distributing pressure evenly through the palms. Keep the ribs down and pelvis lightly controlled in posterior tilt; shorten the range if the lower back starts arching. Neck stays neutral with the gaze slightly ahead of the hands.

  4. Breathing

    Inhale through the nose for about 2 seconds during the lowering phase, then pause briefly at the bottom without holding your breath. Exhale through the mouth over 1-2 seconds as you press up and keep abdominal pressure steady while the elbows extend. Do not hold your breath under fatigue; use one breath cycle per repetition.

Common mistakes

1) Placing the hands too narrowly: if wrist pain appears or pressure shifts to the outside edge of the palm, widen the diamond slightly. 2) Flaring the elbows: if elbows drift toward shoulder height, the movement stops behaving like a diamond push-up and shoulder load rises. 3) Dropping the hips: if the lower-back arch becomes obvious, trunk stability has failed; regain the straight plank line first.

Recommended sets and reps

Recommended sets and reps
Beginner: knee-supported 2 sets x 6-10 reps. Intermediate: standard 3 sets x 8-12 reps. Advanced: feet-elevated or slow-eccentric 4 sets x 8-15 reps.
Tempo
Beginner: 3-1-2-0 (3 s down, 1 s bottom pause, 2 s press, no top hold). Intermediate: 2-0-1-1 (2 s down, no pause, 1 s press, 1 s lockout control). Advanced: 4-1-1-0 (4 s eccentric, 1 s bottom pause, 1 s strong press).
How often
Can be trained 2-4 days per week; leave at least 48 hours between sessions if triceps or front-shoulder sensitivity is present. Low-volume technique work can be repeated after 24 hours. Do not add high-volume diamond push-ups immediately after a heavy chest/shoulder day.
What it trains
Builds measurable triceps strength and improves elbow lockout power for narrow pressing patterns. Trains chest, shoulders, and core on the same plank base, making it a strong no-equipment upper-body strength drill. Compared with a standard push-up, the narrower base of support demands more trunk stability and scapular control.

If something hurts

Knee
Knee pain is uncommon in the standard version and usually comes from hard toe pressure or, in the knee-supported variant, kneeling on a hard surface. If using the knee version, place a pad under the knees and keep the body line without sitting the hips back. If pain is sharp or persistent, stop and consult a healthcare professional.
Lower back
Lower-back pain usually comes from the hips sagging and the lumbar spine moving into hyperextension. Immediate modification: squeeze the glutes, pull the ribs down, and switch to a knee-supported or incline version. If pain does not resolve within 1-2 reps, radiates into the leg, or feels sharp, stop and consult a healthcare professional.
Shoulder
Shoulder pain usually appears as front-shoulder pinching when the elbows flare or the hands sit too high above the sternum. Move the hands under the sternum, keep elbows close to the torso, and shorten the range to the pain-free zone. If pain is sharp, radiates down the arm, or includes numbness, stop and consult a healthcare professional.
When to skip it
Avoid this exercise with acute wrist sprain or carpal tunnel flare, active anterior shoulder impingement, recent rotator cuff surgery, triceps tendon irritation, or sharp pain during elbow extension. The narrow hand position can stress the front of the shoulder in people with marked shoulder instability. In those cases, incline standard push-ups or wall push-ups are safer choices.
