What is the difference between indoor and outdoor rides

Indoor exercise and outdoor exercise will be affected by external factors and there are some differences, I think the main points are as follows: a. Weather factors. Indoor is not affected by the weather, you can play table tennis, badminton, swimming, basketball, mini-football and so on. And in the room if you encounter rainy days, then these activities can not be carried out, as well as if you encounter the sun fierce or three-volt days, outdoor activities are also difficult to carry out. Second, environmental factors. Indoors is more closed, the air is less circulated, so more exhaust fans and ventilation equipment to help remove carbon dioxide, at the same time, because the ventilation equipment has been in use, so it costs some money. Outdoor space is open and the air is good, so you can breathe fresh air anytime, anywhere, and you can also get close to nature and enjoy the beautiful scenery. Third, the site limitations. After all, the indoor venue is certain, so for the number of people, then there are restrictions, more people have to queue up or to be booked in advance of the venue. Outdoor exercise, such as ten thousand people hiking, climbing, etc. is not subject to the limitations of the site. Fourth, the cost factor. Many indoor venues need to charge a certain venue fee, such as gyms, badminton halls, swimming pools and so on. If you set up a venue in your own home, then you still need to spend money to buy equipment and equipment, which is a lot of expenses. And some outdoor exercise does not need to invest in costs, such as outdoor public **** fitness equipment, running and so on. Fifth, the difference between the activities of the program. As an example, like square dancing, this kind of participation in the number of people more dancing activities, are generally carried out outdoors. Indoor such as boxing, kickboxing, etc., indoors can make people more focused, not affected by external factors. Indoor workouts can be done at home, such as yoga and calisthenics. Outdoor exercise, you need to find a venue, find companions together, a little more trouble.
