1. Muscle growth is to break the muscle under load, so rest is very important.

2. The gym coach will make a plan every week. Professional exercisers go to the gym at least five times a week and exercise two parts every day, which can be roughly divided into: chest, shoulders, back, legs and hands, such as pectoral muscles and biceps brachii.

3.48 hours or how many hours vary from person to person, because everyone's exercise quality and recovery quality are different, which is inseparable from your age, physique and quality of life.

4. Final conclusion: Every time you train a part, there will be a normal sore state, so generally speaking, muscle soreness disappears, and you can re-exercise that part when your mental state is good.

To answer your question comprehensively, you may still need to communicate with others in the gym. There are so many things in it that it is difficult to tell the whole story by words alone. In a word, three points depend on practice and seven points on cultivation. This is my personal opinion.

By the way, it is unscientific to say that you can practice every day as long as you are in good spirits, but I believe no one practices part of it every day. It is best to take a day or two off every week. There will be results in the early stage, and the key is to break through a growth bottleneck in the medium term.
