Of course, this is not good. First of all, you can't fully exercise some muscles. The number of exercises each time must meet the requirements, such as arm training and simple barbell bending, which can't play the role of muscle gain every time. In addition, if you do this, it will easily lead to excessive exercise, fatigue and physical strain, which will affect your exercise quality. In the case of excessive fatigue, you may even get tired of exercise, resulting in a fitness plan giving up halfway.

The scientific way is to exercise your legs on Monday and Friday, your chest and triceps on Tuesday and Saturday, your back and biceps on Wednesday and Sunday, and rest on Thursday. As for abdominal training, it can be added at the end of each exercise.
