Hiring a personal trainer is the best investment I've ever made. Here's what I got:
Accountability: It wasn't so easy to skip workouts when I knew my trainer was waiting. So I did it, and kept doing it. Those appointments helped me develop excellent long-term habits.
Facts: My trainer helped me sort through all the conflicting information about weight loss, fitness, and nutrition. He tailored a safe, reasonable training routine based on my schedule and things I like to do.
Motivation: We all need to hear that we're doing a good job, especially when we're pushing ourselves. My trainer celebrated my successes and counseled me through my setbacks, helping me figure out where I went off track and how to get back on.
Results: I've lost 115 pounds and dropped from a size 24-26 to a size 10. That's a 3X to an M. And in June I ran the 20K Dam to Dam race. The most important result is harder to quantify, and that's how much better I feel, both physically and emotionally. The time, the money, and the effort I've spent getting into shape have all been worth it.
