We all know that skipping rope is an aerobic exercise. If you want to lose weight, you must burn fat. When skipping rope achieves the effect of burning fat, it usually takes about 30 minutes to jump. Whether skipping can achieve the effect of losing weight depends not on the number of skipping, but on the time you insist on skipping. If you jump 100 times per minute for half an hour, you will jump about 3000 times at a time. Under normal circumstances, it is difficult for people to do this, and continuous skipping is very bad for their knees. So I personally suggest that skipping should be combined with other sports. You can walk for ten minutes, then jump rope for ten minutes, then jog for ten minutes and then continue jumping rope for ten minutes, so that aerobic exercise can reach forty minutes without feeling too tired.
