Bro this is worse than the guy who does says "1 upvote=10 jumping jacks" How are you even going to handle burning all those calories? A human can only handle 40,000 calories per day, and if you do do a russian twist one minute straight, you will already burn 4 calories, combined doing that 10,000 times and you are already at your max, and not to mention the pushups and squats
