tone up
Firm your muscles
To tone up is to become firmer and more defined, usually referring to muscles through exercise: I've been going to the gym to tone up before summer.
The phrase suggests modest improvement rather than dramatic transformation—less about building bulk than reducing softness.
Can also mean to improve or invigorate more generally: The new management toned up the whole operation.
