Q: I keep reading that the shape of your biceps is genetic and you can’t change it, but in the X-traordinary Arms e-book that came in my Anabolic After 40 package (which I love, by the way!) you say you can change the shape of your biceps. I’ve even seen respected scientists say that changing the shape of a muscle can’t be done. How do you respond?

A: What those scientists are referring to is the length of a muscle. For example, if you have a short biceps, with a gap between the lower part of the muscle and the elbow joint when it’s flexed, you can’t fill in that gap. You’ve simply been born with a high biceps insertion point (like a high calf muscle). To fill in the gap would require muscle reattachment surgery, which we obviously don’t recommend.
