What is the physical quality of people who can jump rope for 50 minutes every day?

If you run for 50 minutes in a row, I don't think it matters. As long as you are physically fit, it is no problem to run at a normal pace for 40 to 50 minutes. But if you jump rope for 50 minutes, I think this physical strength is beyond the range of normal people. Even some professional long-distance runners may not be able to achieve this, because long-term skipping not only tests your leg strength, but also tests Xiao Lu's knees. Even in all joints of your body for a long time, you will feel particularly heavy all over. There is a saying here that there is no light debt at a long distance, which means that if you exercise for a long time, your small weight will affect your overall operation.
