Most middle-aged people work at their desks. Like modern white-collar workers, life pressure is too great, and working hours are too boring and too long. So they can choose to exercise after work, or in the office or at home, expand their chests and stretch their backs, use the trapezius muscles on their heads, and leg press will go to leg press. Both are good exercise methods. You can walk as many steps and climb as many steps as possible on your way home and to work. In daily life, as long as you consume energy, you can exercise. Of course, it is also a good choice to go to the gym outside on weekends. Maintaining a good diet and sleep and avoiding overwork and fitness training will only be counterproductive.
