1. Single-Arm Press-Up 

Muscles Worked: Pecs, Triceps, Delts, Traps, Lats, Core
Sets: 2-4
Reps: 1-6 (work up to 6)
Rest: 60-90 secs

Note: Your strength will dictate whether you will do this using a wall, a bench or from the floor. The toughest of the three options is from the floor.

  • Begin in the usual press-up position with your feet in a wide stance.
  • Turn one hand so that your middle finger is now at approximately 45 degrees, and put your other hand behind your back.
  • With control, slowly lower yourself until your chest touches the back of your hand and your hips stay just off the ground.
  • Pause briefly and then drive yourself back up to the start position.
  • You can now either keep repping on the same arm or alternate arms depending on your current strength. Ideally, do all your reps on one arm, then switch sides and smash out the reps on the other arm, all without putting your knees down.
