How do I build muscle in my arms, chest and abs? And I heard that eating power bars can help gain muscle?
Friday, April 23rd, 2010Im 13 years old and have almost no muscle in my arms. I need a nightly workout plan that will build muscle in my arms, chest and abs. I already have a six-pack but im am most focused on my arms. And should I eat power bars before or after my workout. In the summer, I am going to the gym almost every day. A nightly routine would be great also.
