He could tell that to our nomadic/agricultural ancestors who hauled around rocks or other heavy objects and walk for distances. Fear of injury is moot if you're listening to your body in my humble opinion. They're just afraid of having a scene happen. C'mon, I mean there're people getting injured for the dumbest of reasons and what they're worried about is someone who actually bought a belt and uses it? As if it never come across the user's mind the shit that would entail if he did it wrongly. It's like how years back where people screwed over those who said that barefoot running was beneficial, whining about potential injuries and what not. Guess what. It's all good now in 2011. And the asian build is quite nonsensical. There's no real unique build from one race to another. Body structure is more or less a randomised equation that's based on your own inherited genetics. If we had to put it in a crude manner, just look at your asian bodybuilders. Imagine what they'd tell the clubfitt instructor if he brought up that build issue? Even local fitness coach jon himself does dips with a belt <_<
Here's an incident why i feel clubfitt instructors have no idea what they're talking about. A yoga instructor from clubfitt, who also serves as a regular gym instructor there in a place where I shall not name, likes to make blind comments regarding exercises and form. This was what he once said, "All those people who do olympic squats are wrong." WTF? It's an OLYMPIC squat. If he's about to tell me about squat depth and knee health or spine safety I would mess him up real good because he lacks the appropriate training or knowledge. Seriously, no offence, but I personally feel that clubfitt instructors are made up of a portion of egoistic seniors who believe they know more than what the world has to offer. Other than these 'select' group, the others are actually really nice people.
