Exercising is just a small portion on gaining muscle. Your diet is more important. For instance I'm currently clean bulking by eating 3,320 calories per day and going to the gym 5 times a week going pyramid sets. An example would be like my workout today. Just google things and look up exercises you can do. Figure out what your goal is, like my goal is I am training for 2014 bodybuilding competitions, so my exercises and diet will be different from someone elses.
