Wait so just that it's clear, she used her power of transformation to transform herself into a stronger person?

Indeed. It's another way of saying she's got a sub-power of general "strength speed" boost, directly related to her power rather than thrown in. And, the way it was explained, it's established that she can't get any more due to mental blocks, and that it takes a long time to work her way up. Currently, she can sidegrade her power and perform tricks, but not directly amp up her strength and speed anymore.
