Always work out at your own level. If a standard pushup is too challenging for you, or you can’t get a decent number of reps that way, use one of the intermediate levels (they go up in difficulty from 1 to 3). It’s OK to stretch yourself, but there are no bonus points for hurting yourself.

Exercise: Pushup - a man doing pushups on the floor

Rest on hands and toes. Keep your body straight and your core muscles engaged. Do as many pushups as you can.

Exercise: Pushup level 1 - a man doing pushups against a wall
Intermediate Level 1

Stand about 3 feet from a wall, then do your pushups standing up against the wall.

Exercise: Pushup level 2 - a man doing pushups resting on his knees and hands
Intermediate Level 2

Get down on your hand and knees, then do your pushups with knees on the ground.

Exercise: Pushup level 3 - a man doing pushups with his hands on a bench or low table
Intermediate Level 3

Place your hands on a bench and your feet on the ground, then do your pushups. Lower the bench to increase the difficulty.
