Theres a national level bodybuilder that trains at my gym, his name is daniel mcdonald. Iv seen him almost everyday for the last few years because hes there pretty much all day working with clients. This dude stays that lean year round, he seriously ALWAYS looks like hes contest ready. Its amazing. Dudes always in a great mood. One of the happiest and most outgoing people ive ever met. Although if i was on that level I'd probably always be in a good mood, too. Anyways, from what i hear, a lot of good pharma grade growth is probably what it takes to stay that lean, but who has that much cash for growth.
