I was watching my favorite bodybuilding movie today, Kevein Levrone is Maryland Muscle Machine. When I was watching his bicep training Kevin goes on to discuss what is needed to be a succsessful bodybuilder and it really hits home on the fact that everyone should lift hard and heavy to gain an impressive physique.
He also discusses how people get confused and are always looking for the quickest way, and everything today is so scientific. I can't say it as good as him so I'll post up a link to it on youtube.
Go to 9 minutes 15 secs on the first tape and it leads into the second tape. Or you could watch the whole thing.
