I'm the type who lost weight successfully. I lost 30 pounds in half a year. I keep running for an hour every day and take a day off every week. I don't often use my bike to lose weight, but I have been riding an exercise bike for a while, and the effect is ok, but I don't lose weight as fast as running.

Cycling and skipping are aerobic exercises. Aerobic exercise lasts more than 45 minutes at a time to lose weight, because the sugar in the human body is consumed 30 minutes before aerobic exercise, and then the fat is consumed. Therefore, no matter what kind of exercise, we must persist for more than 45 minutes.

The problem is that skipping rope works well, but who can insist on jumping for 45 minutes at a time? If you keep jumping for 45 minutes, your knees will be unbearable, so considering the length of time, I recommend riding a bike.

Some people say that the combination of the above two sports, I do not advocate this, because these two sports have a greater impact on the knee, in the long run, the knee will be strained, so it will not pay off, compared with riding a bicycle, the impact on the knee is smaller.

To sum up, I personally think it is safer to ride a bike. I hope I can help you.

Note: Don't control your diet. Exercise to lose weight needs nutritional supplements. You should eat three meals a day. Just pay attention to other periods, especially before going to bed.
