What it works

What it should feel like

You should feel it in your triceps, chest, and a bit in your shoulders. It should not be felt mainly in your wrists or lower back.

Most common mistake

A common mistake is letting the elbows flare out. Keep them close to your sides and brace your core throughout the movement.

Keep your elbows close to your sides to place more load on your triceps. The narrow hand position makes the exercise more challenging than a standard push-up.

The diamond push-up places a strong emphasis on the triceps.
