Honestly I don't think they do. Sure they are all in shape, but I remember when I had a trainer for half a year. I gained 5lbs, the whole time. I told him my expectations, I told him I needed size. This does not go to all trainers. Private trainers that cost a whole bunch sure know their stuff... 24 Hour trainers only know how to lose weight.
BTW I gained 45lbs in a year after I dropped my trainer and started doing My own routine.
it really depends on who you are working with and for what purpose. to say nearly every trainer is garbage is ridiculous. could it be that the people saying this have never seen what a real good trainer could do? more probable than the every trainer is shit comments.
Some trainers know what they're doing and some don't. Some of them are in shape and some are not. I see one particular trainer at 24 hour fitness that has been getting fatter every month. Obviously he, and some other trainers, don't understand the concept of a diet. I believe the minimum requirement to be a personal trainer at 24 hour fitness is to just go take a 1 day class.....its something really simple like that.
thats the problem. it is a joke. id say about 75% of them will fit into this class. im sure in years to come that number will get up in the 90's. regardless there is no real need for a trainer for most people.
