How to do a push-up
Hands under your shoulders, body in one line, breathe in as you lower and out as you press. Here is how, and how to scale it.

A good push-up is a plank that moves. Your body stays in one straight line from head to heels while your elbows bend and straighten. That sounds simple, and it is easy to get wrong: hips that sag, a head that dips, a half bend that does not count.
The fix is almost always to scale the move, not to push harder. Drop to your knees, or put your hands on a counter, and do the same careful push-up there. Stop while your form is still clean and rest before the next set.
The moves, one by one
The push-up first, then the knee push-up that scales it, and the plank that trains the straight line.
Push-up

Step your feet back until your body is one line. Breathe in as you lower and out as you press.
- Use a mat or folded towel on a non-slip floor. Get down to the floor slowly onto your hands and knees.
- Place your hands under your shoulders, a little wider. Step your feet back, hip-width apart, until your body makes a straight line from head to heels.
- Breathe in and bend your elbows, bringing your chest toward the floor.
- Breathe out and press back until your arms are straight but not locked.
- Do 4 to 6 push-ups. Stop while your form is still clean, then lower to your knees and rest.
EasierDrop to your knees (a knee push-up), or put your hands on a sturdy counter.
Take care
- Wrists: make soft fists on the floor, or choose an incline push-up with hands on a counter.
- Shoulders: use a smaller bend and stop short of any pinch.
- Back: if your lower back sags, drop to your knees.
Knee push-up

The same movement with a shorter lever. Use it to finish a set when the full push-up goes.
- Use a mat or folded towel on a non-slip floor. Get down to the floor slowly onto your hands and knees.
- Place your hands under your shoulders, a little wider. Walk your knees back until your body makes a straight line from head to knees.
- Breathe in and bend your elbows, bringing your chest toward the floor. A small bend is fine.
- Breathe out and press back until your arms are straight but not locked.
- Do 5 to 8 push-ups, then lower your hips and rest.
EasierPut your hands on a sturdy counter and do incline push-ups, or do fewer reps with a smaller bend.
Take care
- Wrists: make soft fists on the floor, or choose the incline push-up with hands on a counter.
- Knees: add a second folded towel under them.
- Shoulders: use a smaller bend and stop short of any pinch.
Plank

On your forearms, in one straight line. It builds the stiff body a push-up needs.
- Kneel on a mat or folded towel on a non-slip floor.
- Place your forearms on the floor, elbows right under your shoulders.
- Step your feet back one at a time, toes tucked, until your body is one straight line from head to heels.
- Squeeze your legs together and draw your lower belly in a little.
- Hold for 15 to 20 seconds, breathing steadily, then lower your knees and rest.
EasierLower your knees to the mat for a knee plank, or hold for a shorter time.
Take care
- Shoulders: keep your elbows right under your shoulders. Stop short of any pinch.
- Wrists: this plank rests on your forearms, so your wrists stay free.
- Back: if your lower back aches, lift your hips a little or lower your knees.
Practising three days a week
- Do a few full push-ups with clean form, then drop to your knees for the rest of the set.
- Hold a short plank after, to train the straight line.
- Add a rep, or lower for three counts, when you finish a set easily.
