Just wondering how common it is for a gym to keep changing coaches within the gym. Last season we had a great coach and my daughters did very well , for summer my girls have different coaches, and when fall starts up the coaching will change again. We aren't getting new coaches in the gym, just rotating coaches within the gym. I really don't see this as a benefit and have seen my daughters "hold back" in training. What is the benefit to doing this? Is this common?
