Natasha watts: I workout at 5am.. it gets me very energetic during the day.. after having a long day of doing everything else, working out is the last thing I want to do.. exercise gives you energy, so I don't get tired during the day at all.. at night I can relax and sleep good.. the hardest part is getting up at 4:50a to get ready.. but at the end of the day, u are going to be glad you got it out the way..
