Someone needs a fact checker. This math is so wrong. 1000 jumping jacks is only 500 calories burnt. That's only the calories of one pound of fat, 3500 calories. To burn 1 pound do 7000 jumping jacks. That sounds a bit more reasonable, eh?
I want to tell my boyfriend so badly. He'd get so upset. I promised him I wouldn't do it anymore. If I told him, he'd tell my parents, then they'd get mad at me and send me to a hospital. I can't. I want to. But I can't.
