Fitness is a sport to gain muscle and lose weight, which is suitable for the public. I used to exercise for more than a year, and my experience is probably like this. Fitness starts with big muscle groups and small muscle groups. Large muscle groups include: chest muscles, back muscles and leg muscles, while small muscle groups are muscles in all parts of the body. My suggestions are as follows:

1 First of all, you need to know your own situation.

2. You have this situation mainly because you haven't practiced before and haven't developed explosive power.

3, now you have to clear your mind, don't practice too much at first, just one or two, mainly because the posture is correct, can you reach several groups, and how many groups must be regular, so as to be effective!
