You should tell the coach in advance that you need a three-day full-body exercise plan to avoid making some strange long-term plans for you to buy more classes. Remember, whether it's equipment or movements in fitness, the simplest is often the most effective. Therefore, we should practice in a down-to-earth manner, standardize kinematics and do basic things well. When practicing, don't blindly follow others to lift weights, which is easy to get hurt. You should set short-term goals for yourself and compare with yourself, so that you have the motivation to stick to it.
