The Key word here again is “Challenge.”
Pick a number from 6 to 20. Then the challenge is to do that number of reps for each Push-up exercise below. In between each Push-up exercise (or whenever really), you are not allowed to rest, but you are allowed to do one of the following “filler exercises” for as long as you need to.
FILLER EXERCISES:
Scissor Kicks Leg Raises Rowboat Cross Toe Touches V-Sit PUSH-UP EXERCISES: Push-up Uneven Push-up Plyometric Push-up Psycho Push-up Close Grip Push-up Aztec Push-up Twist Push-up Sidestep Push-up Scorpion Push-up Grasshopper Push-up PB Push-up (1 or 2 PB) Military Push-up Spiderman Push-up Plyo Spiderman Push-ups Pike Push-up Hindu Push-up PB Explosive Push-up Spinning Push-up 1 Leg Push-ups Medicine Ball Psycho Push-ups Note: Any Push-up that involves only 1 side, do not do your reps for each side. So for example, if you are doing 10 reps, only do 10 Twist Push-ups, not 10 each side. Another Note: If you are just plain too fatigued to do any Push-ups anymore, try doing some of them on your knees. It is not cheating. This is a challenge, not a mandatory all or nothing workout. It may take you several tries to do this.
