Knuckle Push Up
- Body weight
1) Get in the plank position - start on all fours and extend your legs back behind you. Put your arms directly under your shoulders.
2) Close your fists so your knuckles and fingers are in contact with the ground.
1) Slowly lower your chest to the ground - make sure your elbows are behind your shoulders.
2) Pause at the bottom, then 'push up' (think as if you're pushing the ground away) until you're back in the plank.
