The first month of fitness, the body is still in the adaptation period. In literary terms, muscles are still moaning.
In the second month, you can feel the change of physical quality, less sore, stronger and nervous.
In the third month, you can see the effect of muscle gain.
……
It will be two years before you can become a fitness instructor.
Don't be impatient, impatience may blindly increase the intensity of exercise and damage your health.
Secondly, there is nothing wrong with the practice plan, only what suits you.
I suggest you go to the coach of the gym and ask him what kind of exercise plan you are suitable for, what needs you feel every month in the future, or what is uncomfortable, and ask him to arrange the adjustment of your exercise plan.
The above is my suggestion, I hope it will help.
I wish you success in exercising your muscles.
