Should we run or practice equipment first for fitness?

Fitness suggests doing strength training first. Generally speaking, there are three stages: aerobic ~ strength ~ aerobic The purpose of aerobic exercise is to warm up, so the time is short (5~ 10) minutes, to move the limbs, boost the spirit and enter the strength in a good state. Generally speaking, the strength is 6~8 movements, each movement is 3~5 groups, and it usually takes 40~60 minutes to complete the training. The purpose of aerobic exercise is to reduce fat, so it takes (20~40) minutes or even longer. This is a complete training plan. Running on the treadmill for 30 to 40 minutes or more, how much energy can be put into strength, and strength is a highly concentrated exercise, and I am afraid I have no energy to deal with it at this time.
