About the video:
The longer you’ve been on the fitness journey, the more you realize building muscle is quite slow and difficult. This is especially true if you want to stay lean while adding size. And most guys don’t know how to do this. Their lean bulks turn into dirty bulks, or they get stuck in “permacutting” and go back into a calorie deficit which prevents them from gaining muscle. In this video, I share 5 rules for building muscle without getting fat, which I’ve learned after 15 years in the gym. Implement these I’m confident you’ll see faster results with gaining muscle while minimizing fat gain.
