It depends on your own physical fitness. You know, not everyone has that kind of big guy after exercise. For example, the special forces in China look thinner than the soldiers in Europe and America. General exercise will increase strength. If you have to pay attention to your muscles, I suggest you add more weight to do strength exercises, pay attention to supplementing protein and eat more beef. If possible, you can buy some protein powder and muscle-building powder, provided that you have a heavy load of strength exercises.
