There are many kinds of healthy fat-reducing exercises, and cycling in the gym is a good choice. However, we should pay attention to the time of exercise, neither too little nor too much. In the gym, stationary bicycles are the most popular, because not only can you sit on them and watch TV and listen to music during exercise, but even horizontal stationary bicycles are equipped with backrest, which is really comfortable. When bodybuilders do aerobic exercise through fixed bicycles, they consume glycogen converted from food in the human body within the first 20~30 minutes of exercise. After 30 minutes of exercise, the body begins to break down body fat. Fixed bicycle exercise for less than 40 minutes can exercise the heart and lungs to a certain extent, but it can't consume more fat. If you ride a bike for more than an hour, your body will metabolize more muscle than the fat that the bodybuilder wants to lose. But the more muscles there are, the more calories are metabolized, so it is not easy to get fat. Riding a stationary bicycle or riding a bicycle for a long time is the same as sedentary, which will cause local congestion in the "lower body". If the seat of the fixed bicycle is not well adjusted, there may be perineal numbness and discomfort, perineal pain and so on.
