The market is over crowded with Personal Trainers. Some highly qualified and unfortunately an ever growing number barely qualified. As a Professional Personal Trainer who took the degree route with 4 years of my life dedicated to learning every aspect of human physiology, exercise psychology and body mechanics, I think I deserve the right to be a member of the highly qualified group of trainers. The following link is a great article on what to look for when hiring a Personal Trainer. The only part the writer misses out is the effectiveness of boxing pad work for fat burning, fitness and overall client and Personal Trainer interaction. No writer gets it 100% right but this guy is pretty close and well worth a read before you hire a Personal Trainer.
