How to do it
Push-up with the hands together forming a diamond under the chest to load the triceps. Body in a straight line and elbows tucked; lower until you graze the hands and press without flaring.
Muscles worked
Main muscle: triceps. Also worked: chest. When it plans weekly volume, the generator counts each set of this exercise as one full set for triceps and half a set for each secondary muscle (what is known as fractional counting).
Diamond push-up vs weighted dips: no gear, no added weight
The diamond push-up gives you triceps work with your own bodyweight, with no barbell or parallel bars. Compared with weighted parallel bar dips, your shoulder stays in front of your body and the movement is a horizontal push, kinder to the joint than deep dips, but the load is lower and you cannot add weight as easily. With your hands almost touching, the chest helps less and the triceps takes on more of the work. The narrower the hands, the harder it gets.
Choose it at home, when the plain push-up no longer challenges you at 15 reps, or as a finisher after a push day. It also works to warm up the triceps before heavy lifts. If your wrists complain about the position, turn your fingers slightly outward, spread your hands a bit or use push-up handles. If the full diamond is too hard, place your hands on a raised bench and lower the height little by little.
A detail specific to this exercise: set the diamond under your sternum, not under your face, and build the triangle with your thumbs and index fingers touching. To progress without added weight, go from hands elevated to the floor, then to feet elevated, then to 3-second slow descents with a pause. When you own sets of 15 to 20, move to weighted dips or the close-grip press.

Recommended sets and reps
As a compound lift, it fits in 3–5 sets of 5–12 reps leaving 1–3 reps in reserve (RIR). Prioritize it at the start of the session, when you're fresh.
Common mistakes to avoid
- Letting your hips sag or arching your back: the whole body lowers as one piece, like a plank, from head to heels.
- Sticking with the same version once you can do more than 20 reps: move to a harder variation or add load.
- Doing reps too fast, without controlling the eccentric (lowering) phase.
What the research says
This is a multi-joint lift, and with these the rep range matters less than it seems: Schoenfeld and colleagues (2021) concluded that muscle growth is similar with heavy or moderate loads as long as sets end close to failure, while maximal strength improves more with heavy loads.
You do not need to reach failure on every set: according to the meta-analysis by Refalo and colleagues (2023), stopping one or two reps short gives very similar growth. The generator prescribes it with RIR for that reason.

How Diamond push-up compares with other triceps exercises
Of the 11 triceps exercises in the catalogue, ranked from least to most fatiguing by the values the generator uses, Diamond push-up is number 8.
It sits in the middle of its group: it works as the day's main exercise or as a second or third one.
With different equipment, the same movement pattern offers 2 alternatives, such as JM press and Close-grip bench press.
| Exercise | Equipment | Fatigue | Technique |
|---|---|---|---|
| Diamond push-up | bodyweight | Moderate (0.8 out of 2.2) | Basic |
| JM press | barbell | High (1.3 out of 2.2) | Advanced |
| Close-grip bench press | barbell | High (1.5 out of 2.2) | Needs coaching |
| Weighted parallel bar dips | bodyweight | High (1.6 out of 2.2) | Advanced |
Bodyweight. In the trial by Kotarsky et al. (2018), four weeks of progressively harder push-ups significantly improved bench press 1RM, just like training the bench press itself. It is a strength result, not a hypertrophy one, and the condition is the word progressive: the exercise has to keep getting harder.

Frequently asked questions
What muscles does Diamond push-up work?
Diamond push-up mainly works the triceps muscle group, plus synergist and stabilizer muscles depending on the variation.
How many sets of Diamond push-up should I do?
Between 3 and 5 sets per session, adjusting the total weekly volume for triceps to your level (about 10–20 sets per muscle per week).
Do diamond push-ups work the triceps more than regular ones?
Generally yes: they shift more of the work to the triceps and less to the chest, because with your hands close together the chest helps less. In exchange, they are tougher on the wrists and elbows. If they bother you, try a hand width between the diamond and the classic push-up, still keeping your elbows close to your body.
