In the 70's trainers were trying to turn people into bodybuilders.
In the 80's trainers were trying to turn people into aerobics junkies.
In the 90's trainers were trying to turn their clients into trained seals on unstable surfaces.
In the 2000's trainers were trying to turn their clients into rehab (i.e., corrective exercise) patients.
Now, in the 2010's trainers are trying to turn their clients into powerlifters.
I wonder what the next decade's "best" training method will be?
I also wonder if it will ever become "in style" for trainers to actually fit the training methods to best accommodate the client's goals.
