The subject wants to ask me why I can't add an updated version when I download skipping rope and join another team every day, but my mobile phone can't? Just add two classes to the APP as an administrator.

1, skipping rope is not allowed to join two classes every day, and you can only sign up for one class. Follow the progress of the class and practice every day.

2. Skipping rope is the best slimming exercise. The test shows that jumping 10 minutes and jumping 140 times per minute is equivalent to jogging for half an hour. Skipping rope can not only help you lose weight, but also make your muscles well-proportioned and strong, and at the same time, your respiratory system, heart and cardiovascular system will be fully exercised.
