The effectiveness of using a skipping rope depends on a number of factors, such as the intensity and timing of your workout, your skipping technique, and your individual skills and training goal. In general, if you want to gain health and fitness benefits, it is recommended that you jump with a skipping rope for at least 10-15 minutes a day, 3-5 times a week. You can do this in one session or divide the workout into several shorter sessions throughout the day.

If your goal is to burn fat, you can increase the training time or increase the intensity of jumping. However, remember to always start at a moderate intensity and then gradually increase the pace and training time as your fitness improves. Also, don't forget to warm up properly before training and stretch afterwards to avoid injury.
