Diamond Push-Up

Move · Resistance Training · Movement, Typed Supps

Moving the hands together does not add weight — it moves the effort onto the triceps by taking leverage away from the chest.

Stage by stage

Set-up (Narrow base, wrists extended): Hands under the sternum narrow the base of support and place the wrists in more extension, which is often what limits the set.
During the set (Elbow moment arm increases): Deeper elbow flexion and a longer elbow moment arm raise triceps demand while limiting the pectorals' horizontal adduction contribution.
Immediately after (Lockout fails first): Failure at the extension end of the range is the signature of a triceps-limited press rather than a chest-limited one.
Months later (Triceps size and lockout): Triceps hypertrophy and lockout strength improve, transferring directly to bench press and dip.

Muscles trained

Primary: triceps
Secondary: abs, chest, serratus anterior

Intensity

8 METs (Calisthenics (e.g., push ups, sit ups, pull-ups, jumping jacks), vigorous effort).

Time to effect

Weeks: Wrists and elbows typically need a couple of weeks to adjust to the narrower hand position and the steeper angle it puts on the elbow joint.
Months: Triceps size and lockout strength build noticeably faster than with a standard push-up, and that carries over directly to pressing movements like the bench press and dip.

Common myth

"Diamond push-ups are an advanced move you have to earn the right to attempt." In reality: The extra difficulty comes from the narrow hand position increasing the triceps' share of the work and reducing the chest's mechanical leverage, not from needing elite strength. The same regressions that make a standard push-up easier — knees down, hands elevated on a bench — work just as well here.
