It takes about 60 minutes to run or brisk walk or a mixture of the two. I don't know about your physical condition, but it will take at least 30-45 minutes to have an effect. Then there is anaerobic exercise, because I heard that anaerobic exercise can help you burn fat faster, but mainly aerobic exercise. Actually, I don't do much about this, but I heard that the weight loss effect is quite good, so I need to exercise less and less.
As for classes, I usually exercise and yoga more often. Spinning is very intense, and the slimming effect is said to be the best, but I didn't shoot it very much, because the music in it is too big for my wife, and I will get tinnitus after class, hehe. These courses depend on your time and hobbies, and I can't say anything more.
As for diet, I think people who lose weight know to eat less calories, fry less and so on. , but it is often not easy to do. If it's easy to do it, they won't get fat, hehe. But it's better to control it. Think about it. The fat you consume after exercising in the gym for two hours may make you lose all your efforts to eat sorbet. That's a real pity. Eat less and eat more, skip meals at night, and lose weight with apples, which can be found online. The key depends on your own control.
Haha, the above is my little idea, you can refer to it! Wish you success!
