? When running on the indoor treadmill, the treadmill has the function of shock absorption, which will reduce the wear of the knee joint. There are different sports items to choose from on the treadmill, which will increase the fun of sports, regardless of the weather and time.
Running on an indoor treadmill is different from running outdoors, which is why many people feel very tired after running outdoors.
? Running outdoors can see the scenery and breathe fresh air, which is relatively less boring, but it will be more uncomfortable when it rains in winter. Running outdoors, running the same amount at the same time will consume more calories.
Outdoor running feet directly touch the ground without recoil of shock absorber, which is harmful to knee joint.
? ? Opinions vary. After all, different people have different opinions. But when you think about it, there is still a considerable difference: 1. Although the air outside is good, the smog is getting heavier and heavier due to atmospheric pollution. Although the gym is good, the carbon dioxide exhaled by people during exercise is heavier than usual, which leads to bad air. 2. The road operation environment is more complicated, so the probability of accidents will be higher, such as tripping over uneven roads. 3. Running posture will lean forward more on the road without knowing it will aggravate the impact on the knee joint. If the posture on the treadmill is slightly wrong, it will make noise and inadvertently remind you to pay attention to your running posture.
