Many trainers are extraordinarily gifted bodybuilders, with beautiful, chiseled muscles.
A lot of that has to do with genetics. Some of these guys I think just have to show up at the gym in order for their bodies to grow into gleaming perfection. Unfortunately, none of that helps them train someone who has to fight for every ounce of muscle he can achieve. I also see lots of trainers, including many women, who are extremely knowledgeable, focused and disciplined. I have so much respect for these trainers, but I can't help noticing that sometimes they can be too correct, too focused.
