During his session yesterday, "Jason" told one of our trainers stories that used fear as a motivator instead of love. One example was his trainer threatened to take a $1 out of his wallet each time that the walked on the side of the treadmill. Using (hopefully) empty threats and using fear as a motivator doesn't earn the respect of your clients. Sure, they may comply and you will see the behaviors that you want decreased be reduced. But in no way does it lead them to wanting to come back or to be active outside of their scheduled sessions.
Instead, motivate with love. We (Specialty Athletic Training team) believe that our clients should always leave wanting to come back. We strive to make exercise fun, use positive reinforcement during our instruction, aim to increase the self esteem and confidence, and make sure that they leave with a smile.
