Wide push-up on knees
- Start on your knees, bring your hands out slightly wider than shoulder width.
- Lower yourself to the floor, keeping your spine straight with your abs pulling in.
- If your lower back is dipping, or your butt is in the air as you are doing the push-up, this means you aren’t engaging your abs correctly. Suck your belly in to your spine and if you can only go down halfway keeping this good form then do this until you build up the strength to go further.
