Skipping rope, although not as much as 15 kg, is still possible for about three months 10 kg. If the base number is large, it will be easier. However, it should be noted that it is necessary to step by step, not to rush, slow down at first, jump for a few more days, and then slowly increase the number of skipping! Generally, you should jump 3000 times a day, and do a good leg massage after jumping, so you don't have to worry about your legs getting thicker! Come on!
