How many calories do i burn by doing 100 jumping jacks everyday 7/week?
Far less than you think. About 100 in a week. Thst is 1/35 of a pound. Exercise for tone not weight loss. Eat less and better for weight loss.
725 jumping jacks = 100 calories, if you want to lose weight with jumping jacks, try doing ten minutes of them at 1.25 repetitions per second! :)
