Noticeably developed musculature that must have come from extensive training, body building or otherwise. The body has visually "bulked up" and has become obviously thicker.
If the physique is muscular with a belly like many wrestlers and bodybuilders, consider adding the plump tag as well.
Do not use together with the toned tag when describing one character.
If the character has an athletic build that’s not overly bulky, use toned instead.
For the actual muscle tissue under the skin (such as seen in anatomy pictures), please use flesh.
