To answer the original question, YES Flex was lazy.
I've seen his first video, Hard Body, and it's rediculous. He doesn't push himself, never going to failure. It is never looking like he is really strugglin to get the weight up. And if you see the numbers he puts up, i'm seriously tellin you. 80% of the people on here could do that.
Whenever I see that vid, it doesn't make me wanna train. I just get green with envy because Flex is one on the best looking BB'ers ever.
Flex was weak and lazy, but he had the genetics to get away with it.
Peace
