Why not make it 20,000 i can do this in 21 days any challeger.
But is it good for health to do so many crunches?
I accept the challenge! Let me know how you do :)
I'm going to try doing 100 pushups and 200 squats to go along with it... hopefully it'll go well
Have fun everybody
Its all about what strength and sports you do. Example i do yoga, walk and bodyweight workout watch include press up so on.
