If you practice well, once a week is enough for a part of the big muscle group. If you are energetic, practice twice, once to load the limit and once to increase muscle endurance, such as chest, back and legs. Small muscle groups can be practiced twice a week, and the time can be arranged after the large muscle group, or one day can be arranged separately, such as biceps brachii, triceps brachii, shoulders (some people say it is a large muscle group, but I think it should be a small muscle group, including the front, middle and rear bundles of deltoid and trapezius), and abdominal muscles can be practiced every day, but at least once every other day.
For example, you can refer to it, but it may not be suitable for you:
On Monday, I mainly practice chest-assisted triceps (optional) abdominal muscles.
On Tuesdays, I mainly practice biceps (optional) and abdominal muscles (optional).
On Wednesday, I mainly practice shoulder and abdominal muscles.
On Thursday, I mainly practice the abdominal muscles of my legs (including my calves) (optional).
Friday biceps triceps and forearm abdominal muscles
You can practice your abdominal muscles once after two days off on Saturday and Sunday (optional).
When I just have a good rest, I have big muscles on Monday and Tuesday, and I will be a little tired. There are many small clusters in the back, and I'm tired, so I just relax a little. It is also appropriate to take two days off. Of course, it is not necessary to practice for five days in a row, and arrange a day off in the middle.
