The diamond push-up is a bodyweight exercise that primarily targets the triceps, while also engaging the chest and shoulders. The unique hand placement forms a diamond shape with the thumbs and index fingers, increasing the intensity on the triceps compared to a standard push-up.

1. Start in a standard push-up position with your hands close together, forming a diamond shape with your thumbs and index fingers.
2. Keep your body in a straight line from head to heels, engaging your core.
3. Lower your chest towards the diamond shape by bending your elbows, keeping them close to your body.
4. Push through your palms to return to the starting position, fully extending your arms.
5. Repeat for the desired number of repetitions, maintaining proper form throughout.
