For example, running and cycling should last at least 45 minutes at a time.

The first 20 minutes are just a warm-up. If you don't do it for 45 minutes, it is basically a waste of practice. Even if it works, it won't be too obvious.

Don't overdo your exercise. Don't run or ride a bike too hard. The most important thing is to continue.

Besides running and cycling, Latin dance and pedal dance are also good ways to lose weight.

Remember one sentence, the most important thing to lose weight is to keep exercising for a long time. Not a short explosive force. If your sister has time, you'd better let him exercise for more than 2 hours every day. Combine running with cycling. You can take a break in the middle, 5- 10 minutes.

It will be effective in a month. Another simple and safe way is to practice yoga.
