Cool success story, Tim! The thing is, weightlifting requires rest to allow for your muscles to recuperate and grow. So more time spent lifting isn't necessarily better! It can lead to overtraining.
28 lbs of solid muscle is a lot to pack on in just two months, especially when you're only getting 2.5 hours of sleep per day. Difficult to believe at first, but nothing's impossible. Tynan says he's legit so I was looking for him to spit knowledge backing it up, provide a link or something. I was previously under the impression that polyphasic sleep and building muscle mass are imcompatible.
