The benefits of riding a bike
1. Bicycle is one of the best tools to overcome heart function problems. More than half of the people in the world die of heart disease. Cycling can not only compress blood activity through leg movement, but also draw notes from the end of blood vessels, but actually strengthen microvascular tissue at the same time, which is called collateral circulation. Strengthening blood vessels can protect you from the threat of age and keep you young forever.
2. Habitual cycling can expand the heart.
Otherwise, the blood vessels will become thinner and thinner, and the heart will get worse and worse. When you get old, you will experience the troubles it brings, and then you will find how perfect riding is. Cycling is a sport that needs a lot of oxygen. There was once an old man who finished riding 460 kilometers in six days.
