If you are just starting fitness exercise, the first step to take every day is to warm up, usually running on the treadmill for 3 kilometers or 10 minutes, sweating slightly, in order to make all joints of the body move. Take a break (about 5 minutes), and then do equipment exercise according to your own goals. Do two kinds of strength training every day, not too much, and then do other exercises a week later.
One principle: the exercise should be balanced, the time should be relatively fixed, and the number of groups of each instrument should be qualitative and quantitative, because muscles also have memory function. When you start practicing, you can measure it a little bit, step by step.
