trainers or professional bodybuilders opinion needed
I have read that the body can only produce 2-3 pounds of muscle a month and up to possibly 25 pounds a year? Im sure after 5 years this is still a true proven fact, right? I have a friend who swears that he worked out 3 weeks straight, 4 days a week and gained 19 pounds of pure muscle then claims he had to stop working out…
