www.ExerciseRoutinesBlog.com – How to Build Muscle: Rusty Moore’s Method. If you don’t know who Rusty Moore is, you should check out his 4 free videos. He goes against the bulky “meathead” look and shows how to build lean muscle. He uses the principles of sarcoplasmic and myofibrillar hypertrophy to not only build muscle fiber, but to make it expand so the muscles look large and well defined. Anyway, if you want to know how to build muscle, just watch his videos. He explains it much better than me.
