The diamond push-up is a close-hand variation of the standard push-up in which the hands are placed together beneath the chest to form a diamond shape with the thumbs and index fingers. This narrow hand position dramatically increases triceps involvement while still engaging the inner chest and shoulders. It is an excellent equipment-free exercise for building pressing strength and arm size once standard push-ups become easy.
Muscles Targeted
- Primary: Triceps brachii
- Secondary: Pectoralis major (especially the inner/sternal fibers)
- Tertiary: Anterior deltoid, core, serratus anterior
Starting Position
Begin in a high plank with your hands together directly under your chest, index fingers and thumbs touching to form a diamond shape. Extend your legs behind you with feet together, and set your body in a straight line from head to heels. Brace your core, squeeze your glutes, and keep your shoulders set down and back.
Execution Steps
- Brace your core and keep your body rigid in a straight line from head to heels
- Bend your elbows to lower your chest toward your hands, keeping the elbows tracking back rather than flaring wide
- Lower under control until your chest lightly touches or nearly reaches your hands
- Pause briefly at the bottom while maintaining full-body tension
- Press back up by extending the elbows until your arms are fully locked out
- Repeat for the desired reps without letting the hips sag or pike
Form Cues
- Keep the elbows tucked: Let the elbows travel back along your sides rather than flaring outward
- Maintain a straight body line from head to heels—no sagging hips or raised glutes
- Keep your hands directly under your chest, not under your face or stomach
- Lower under control and press explosively to maximize triceps work
- Keep the core and glutes braced throughout to protect the lower back
Common Mistakes
- Flaring the elbows wide: This shifts load off the triceps and stresses the shoulders.
- Sagging hips: Letting the hips drop breaks the plank line and strains the lower back.
- Partial range of motion: Not lowering far enough reduces the stimulus to the triceps and chest.
- Hands too far forward: Placing the diamond under the face lengthens the lever and overloads the shoulders.
- Rushing the reps: Using momentum instead of control reduces tension on the target muscles.
Variations
- Knee diamond push-up: Performed from the knees to reduce load for beginners
- Incline diamond push-up: Hands elevated on a bench to make the movement easier
- Decline diamond push-up: Feet elevated to increase difficulty and upper-chest emphasis
- Close-grip push-up: Hands shoulder-width but close, a slightly easier triceps variation
- Tempo diamond push-up: Slow lowering phase to increase time under tension
Tips for Progression
- Increase reps: Build to 12-15 strict reps before progressing to harder variations
- Elevate the feet: Move to decline diamond push-ups to add load
- Add tempo: Slow the lowering phase to 3-4 seconds for greater intensity
- Add a pause: Hold the bottom position for one to two seconds each rep
- Add weight: Use a weight plate or vest once bodyweight reps become easy
Training Notes
Include diamond push-ups in your push or arm training one to two times per week, typically as a triceps-focused accessory after heavier pressing. They work best for 8-15 reps performed with strict form and a controlled tempo, resting 45-90 seconds between sets. If standard diamond push-ups are too difficult, start from the knees or on an incline and progress as strength improves. Because they emphasize the triceps while still training the chest, diamond push-ups are a convenient way to build pressing strength anywhere without equipment.
