Z, if conditions permit, it's best to do everything. Equipment belongs to anaerobic exercise, which can increase muscles. Running is mainly aerobic exercise, which is healthier. There are three kinds of exercise, besides aerobic exercise and anaerobic exercise, there are stretching exercises. Only when all three exercises are done can we talk about real bodybuilding. Do stretching exercise first, then run, but be careful not to be too tired, otherwise you can't practice the equipment. You should also warm up when practicing equipment. If you don't warm up, you will get hurt easily. Warm-up has two meanings: 1 adapt to your heart and lungs, and 2 adapt to your muscles. So it's good to run first and then practice the equipment. When practicing equipment, it is best to do two groups of exercises with relatively small weight first, which is considered as warm-up. Then use your own limit (8 *3 groups) to give the muscles a strong stimulation.
