Very impressive. If you lose weight to 42 pounds mainly by exercise and ensure that you can stick to it every day in the future, you probably won't rebound. If you lose so many pounds quickly by exercising and dieting, I'm a little worried about your health, because whoever loses 42 pounds in two months is not good for your health, and the chances of rebounding will be great. Lose weight step by step. We should not only look at the slow weight, but also pay attention to ensuring weight loss without affecting our health.
