It takes at least 30 minutes for each exercise to have a good effect. If the time is too short and the calories consumed are not up to the standard at all, then losing weight will be very slow. Stick to it for more than 30 minutes, and then you can have a rest and adjustment of 5- 10 minutes. Pay attention to stick to it for a while, if it takes a day or two, it will have no effect.
