(crossfitmach5.com) crossfit mach5 R&D in 1234 Niagra Bl. in Burbank CA is a horrible gym. The coach is copleatly unprofessional and since this is an extreme sport..proper form and technique must be followed at all times. Also it is very important to scale your weight accordingly. Fresh off the bat they make you use weights that most people can't handle and have you doing advanced weights and movements that lead to my injury. I puts all my trust and faith in my coach there and what i got in return was a nasty injury. He decided to open a gym after a year or 2 of training in crossfit with no experience at coaching and no knowledge of anatomy and physiology of the body.Makes you sign a disclaimer to prevent law suite and hides behind it when he injures someone. Also its a makeshift gym out the back of his house in a garage and pool area which is ghetto and unsafe.He charges cash and doesn't pay taxes as it is not an official business, almost like a yard sale gym. progress is supposed to be mesured in a book after each work out, but what happens when you are injured and cannot complete the workouts..he screams and hollers at you and blames you for listening to him. Now i go to a real crossfit gym that is professional and has world class coaches and athletes that train you and teach you as you go. You start with weights that fit your level and move forward based on performance.
