I agree with the viewpoint of anaerobic fat reduction. Your coach is right. This is also the case with my current teaching ratio. But the biggest drawback of this method is that it is too slow. But if you want to change your body shape, you have to pay the price. You think your original body shape has developed for many years. Anyway, it takes one tenth of the time to change it.

In the process of reducing fat, the proportion of diet plan is 70% and training is 30%. Of the 30% training, 70% is anaerobic training and 30% is aerobic training. The planning cycle takes 3-4 months. There won't be too many problems in the general training plan. The key is diet. Let your coach start with diet and change his thinking about diet. I believe you will get good grades.
