mixed on this one, I see people working out daily with their online printouts or magazines in their hand. During the course of my training session I DO NOT stop to correct someone. I have been asked a question during training, but I respectfully inform person am training but would be happy to assist when done. On the flip side if I am working out in the gym and someone is performing an exercise mechanically incorrect, I have approached and shown them “another” way to perform to get possibly more effective results. This is also a great opportunity to develop a relationship and dialogue for a new client.
