Hey, cex2y! I've heard so many times this problem, and i really want to suggest you couple of things! First of all, you should wake up early and do some physic exercisies. Start with small things. The secret is simple, when you'll decide to go to the gym, it will be hard, but when you start to practice it, it will become your pasion. Please, don't think too much, don't be lazy! It's your health, it's your all, do it!
