This practice will only make your body more uncoordinated. The proportion of upper body and lower body is out of balance.

I suggest you make a fitness plan according to your physical condition:

If you are obese, you can train more, but not more than 1.5 hours (warm-up).

If you are thin, it is recommended not to warm up for more than 60 minutes.

But your requirement is fitness, so aerobic exercise can be strengthened.

Training should be regular: on the first day, you can't practice anything else.

The suggested initial training plan is: Saturday 1: chest.

Second week biceps brachii

After the third week, shoulder

At the 4th week, triceps brachii

5 th week leg

Take a day off and take turns cycling.

The training plan that has been implemented is:

Week 1 week: chest and triceps brachii

Tuesday: Back of biceps brachii

Wednesday: Legs

Thursday: Abdomen

On Friday, the whole party will pass the customs (not too heavy)

Take a day off.

The above requirements require 3 movements per day, with 8- 12 movements in each group (the requirements are standardized, the movements are in place, and the load and deformation of the movements are prohibited).
