If you exercise for a long time, the fitness effect will definitely be better. The stair climber in the gym has a good fitness effect. I believe that if you can keep exercising for more than two hours every day, you will definitely have a significant effect soon. At the same time, don't exercise for too long, because extremes meet, and you need to arrange your time reasonably. At the same time, you should also arrange your diet reasonably during exercise and eat more high-protein foods, such as eggs, tofu, milk and so on. I hope I can help your suggestion.
