Oh... my... god...
I watched about the first 16 seconds of that and couldn't watch anymore. That is god fucking awful. That is just BEGGING for a serious injury; herniated disc, torn ligaments, strained muscles, you name it. Fitness should always be about FUNCTIONAL strength and movement. If you can't move the weight through a proper range of motion with proper core support and mechanics, the weight is too much. Sure there is a role for high-weight/low-rep strength training, but it has to be done right or you're not developing anything, just causing damage. I hope that place either gets a competent coach or shuts the fuck down before someone is seriously hurt. That was horrifying...
