How to do the Push-Up

  1. Start in a plank, hands slightly wider than your shoulders.
  2. Brace your core and squeeze your glutes so your body is a straight line.
  3. Lower until your chest is just above the floor, elbows ~45°.
  4. Press back up without letting your hips sag or pike.

Frequently asked questions

What muscles do push-ups work?

Push-ups work the chest, triceps and front deltoids as the primary movers, with the core (abs and serratus) working hard to keep the body rigid throughout.

Are push-ups enough to build a chest?

For beginners, yes — push-ups build real chest and triceps strength. As you get stronger, add reps, elevate your feet (decline) or add resistance to keep progressing.

Why do push-ups hurt my shoulders?

Usually the elbows are flaring straight out to the sides. Keeping them at roughly 45° from your body puts the shoulders in a safer, stronger position.
