It’s early morning, and you arrive at the gym to discover a voice message from your 8:00 am client, Mary. She has called to let you know she will be unable to make her appointment because she has strained her back and is laid up in bed—for the third time this month.

These so-called trainers are giving reputable and ethical personal trainers a bad image. As a former college instructor of exercise science, I used the show’s trainers, Bob Harper and Jillian Michaels, as examples to my students of what not to be and how not to train.
