A good figure must have a good body combination, which refers to the proportion of bones, muscles and fat in the body structure. Usually, "fat" means that there is more fat in the body combination, and "strong" means that there are more muscles in the body combination. If you just "can't feel muscles", you can strengthen muscle strength training.
