The fitness instructor doesn't continue the class. What should I do if I need a new coach for the rest of the class?
See how the new coach works. If you want to compare the previous coach. I'm still used to the training methods of previous coaches. You can drop out of the gym or find a former coach to train. If it really doesn't work, exercise for a period of time to try the effect and see the rationality of the training plan. I hope it will help you and I hope it will be adopted.
