Call me stupid but I really don't want to take a rest day during my workouts. I'm concerned I'll take a rest day and then don't get back to the gym. How necessary is this?
Sure sleep is important, but just sleep isnt enough. If you do excercises to work out muscles the muscles that got strained and are repairing themselves take around fourty eight hours to repair, but if your workouts aren't too intense maybe take one or two days off after two or three days of excercising in a row. Remember over training can have bad effects.
