In the last 10 years, I've had two private trainers and four gym-based trainers. I had to dump each private trainer. Each had, after a while, become unreliable. I know they all aren't. It was just my luck. I'll never chance my money and time on another. My current gym trainer is a young guy in his first full year of work. Without a lot of experience yet, he comes nevertheless directly out of the latest health and fitness education from a highly reputable college (George Brown, for those in Ontario, Canada). So he's up on all the latest REAL study and science. With 30 years separating us in age, we don't have a lot in common to talk about during workouts, but he's energetic, enthusiastic, not a part-timer -- this is his chosen career, not just something to do. So, I'm very happy. And getting results!
