Some people are not heavy, but why are there "bye-bye meats"?
In fact, our meat worship is due to muscle atrophy and fat accumulation caused by long-term lack of adequate exercise of the triceps brachii behind the arm.
So you can do strength training to stimulate the triceps brachii, thus tightening your arms.

Common push-ups and flat support require the whole arm to exert strength, which can stimulate the triceps brachii very well. If you can't, you can do it on your knees first, which will be much easier.
After a period of time, the basal metabolism is improved, the cardiopulmonary function is strengthened, the muscles are more elastic and balanced, the muscle strength and endurance are improved, the body fat rate is reduced, and the body shape is getting healthier and stronger.
