Hi, my son is a very fit; he s been doing gymnastics for years. He wants to raise money for a children s charity to celebrate his 11th birthday and has come up with a plan to do 1100 push-ups in 2 hours. Seems a lot to me, but then I m not as fit as him!. He comfortably does 250 per day in training. The plan is that he ll do them in sets of 10 (at about 1 per second), then rest for the remainder of the minute, etc. Are there any health implications?
