Prime X Factor I wanted to show you how to build muscle fast in as little as 7 minutes. No, I don't mean 7 minutes to put on all that muscle because that is biologically impossible. What I'm saying is how you can do it in a short 7 minute muscle workout that focuses on the important aspects of building muscle rather than the misinformation most people follow on their day to day routines.
