Hello, I personally suggest you use skipping rope. It is a full-body exercise, and it can also enhance the jumping ability of the lower body. No special guidance is needed, and no big venue is needed. Not limited by time, space and climate. When you have time to exercise, you can pick up the skipping rope. Walking race is a professional sport. It is best to have a good effect after guidance and have a suitable venue. Of course, walking faster at ordinary times also has a good effect.

I hope my answer can help you, thank you!
