If you do this for a long time, your knees will gradually wear out, which will lead to injuries step by step, and even more serious will lead to problems in your own actions. Therefore, it is not recommended that overweight people choose skipping rope.
If you are overweight, but want to exercise, this is good, and I personally agree with your idea. At the same time, it also supports you to exercise and lose weight, knowing that you have great potential. But I don't recommend skipping rope.
There are many ways to exercise or lose weight. I suggest that overweight people can choose fast walking, running or spinning and other sports that are less burdensome on their knees. If I seldom exercise myself, I suggest starting with a brisk walk. Because there is not much calf exercise at ordinary times, if you start running, you will soon feel calf muscle pain. First, maybe you will give up soon; Second, if you suddenly increase the burden on your knees, you will be easily injured. So you can walk for a while, get used to it, and then slowly transition to running, walking and jogging.
