I won’t comment on the safety of a kid doing thousands of pushups because I have no idea (doesn’t sound like a great idea though) but I would be more concerned about how the kid is being treated by his parents. His training regime must be pretty gruelling.
Someone should tell Kilian Jornet, the greatest mountain runner ever, who was doing 3 week backpacking trips through the mountains when he was four years old, and who was biking 200 mile races at age ten
@dawn16 Well there is a difference to be physically fit and all the stress that's been put on the joints of the little fella because of the push-ups I guess?
