The related training methods can be consulted by the gym instructor, or you can download and watch the tutorial yourself. When the time comes, eat more high-protein food and protein powder (there are many on the Internet, and specialty stores can consider PQfitness, etc. ) to assist muscle production.
As long as you persist, you won't lose weight. It's fair to exercise to lose weight (provided that you don't eat indiscriminately). As long as you pay, you will get something back ~
