Knee push-ups, built up slowly
The floor push-up with a shorter lever. Keep the line from your head to your knees, and build from a small bend.

A knee push-up is a real push-up with a shorter lever. Your knees stay on the floor, so the load is smaller, but your body must still hold one straight line. It is the step that makes the floor feel familiar.
A small bend is fine to begin with. Lower only as far as you can keep your hips in line, and press back smoothly. Wrists complaining? Make soft fists on the floor, or go back to the incline push-up for a while.
The moves, one by one
Set up on a mat first, then see the plank that supports the move and the full push-up that follows.
Knee push-up

Hands under your shoulders, knees walked back until your body makes a straight line from head to knees.
- 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.
Knee plank

A plank with your knees down. It teaches you to hold your body in one line.
- Kneel on a mat or folded towel on a non-slip floor.
- Place your forearms on the floor, elbows under your shoulders.
- Walk your knees back until your body makes a straight line from head to knees.
- Draw your lower belly in a little and hold, breathing steadily.
- Hold for 15 to 20 seconds, then lower your hips and rest.
EasierHold for 10 seconds, or rest your hands on a counter and lean in (a counter plank).
Take care
- Shoulders: keep your elbows right under your shoulders. Stop short of any pinch.
- Knees: put a folded towel under your knees.
- Back: if your lower back aches, lift your hips a little or rest sooner.
Push-up

The goal. Try it for a few reps and drop back to your knees when your form starts to slip.
- 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.
A simple week
- Three days: a few knee push-ups, then a rest, then another set.
- Add a short knee plank at the end to practise the straight line.
- Move to the full push-up on one day when the knee version feels easy.
