If you practice a muscle group every day, it is best to finish it in about 50 minutes, not more than 60 minutes. You need to reduce the interval between groups, so that the muscles can get better and deeper stimulation. If you practice a large muscle group and a small muscle group a day, the time should be controlled within 70 minutes. The interval between groups is controlled at 30-45 seconds. Basically, you finish one group, take a break and then continue to prepare for the next group. The interval of leg muscle exercise in each group can be extended to one to two minutes.

If you really want to look good all over, you'd better adjust the training content. Practice five days a week, the first day is chest muscles and triceps brachii, the second day is back muscles and biceps brachii, the third day is shoulders, the fourth day is legs, and the fifth day is abdominal muscles. Then rest for two days. In this way, your muscle exercise will not conflict, and you can practice all over your body. You shouldn't exercise your legs before, but if you don't exercise your leg muscles, it's difficult to practice your upper body muscles, because leg strength exercises can stimulate a large increase in hormone secretion, which is good for the growth of your whole body muscles.

Every two months, we should carry out a week of small load recovery training, so that muscles can be fully cultivated and adjusted during this week, so that muscles can grow best and their strength can grow fastest.
