this is a description of a girl who is unusually strong for her sex but does not have huge bulging muscles, usually from spending time casually lifting weights in a gym.
"Whoa did you see what that girl just power-cleaned? She doesn't look big enough to be lifting that much!"

"Oh, that's just one of the trackies. They're all super girl-ripped."
