Muscle Growth
When your muscles are growing bigger. Especially relevant if the character doesn’t have much musculature to start with. This can involve muscles being grown conventionally (i.e., hard work at the gym), but usually there’s something more going on that gives the growth a push.
Compare Muscle, which can be just about having big muscles, and Size Growth, which involves getting bigger overall.
