It's not that you don't eat, but that you should control your diet by eating miscellaneous food, eating nutritious food and eating everything but not too much. Especially during exercise, it is necessary to supplement dairy products and protein, which will help to reduce fat and gain muscle and improve metabolism.
Aerobic exercise is the best, and it is completely suitable for doing at home. You can choose aerobics, such as aerobics in Duoyan Zheng or aerobics in Pan Ruodi. The former is easier and the latter is more difficult, but both of them are very effective for body slimming, including local slimming actions. For example, Duoyan Zheng 4 is a mat exercise, dedicated to thin belly and waist. You can choose to do it three days a week and stick to it for one month.
For the chest, it is suggested that after 30 minutes ~ 1 hour of aerobic exercise, another 30 minutes of anaerobic exercise, such as chest expansion exercise and muscle exercise, will have a good and quick effect, and at the same time eat more high-protein things such as protein powder and egg white.
I hope it helps you.
