Training: firstly, aerobic training reaches 3 hours, and secondly, enough protein is taken in the diet. If you lose weight normally or safely for one month according to scientific fitness training methods, you should be able to reach 2-4KG. This is just a relative figure. If people who lose weight are heavier, they can lose more through proper training and diet.
To lose weight, I suggest you run on the treadmill 10 minutes to warm up, and then do strength training, which can consume glycogen in the body. After strength training, you can do aerobic training for 30 minutes, that is, running, swimming and skipping rope, so that you can directly consume fat when glycogen is exhausted, which can improve the effect and shape your body while losing weight.
