While doing dishes, do calf raises

• Do at least 20 calf raises, where you stand with your feet shoulder-width apart and raise up onto the balls of your feet, then lower back down to the floor.
• After 20, take the towel and start drying while you squat—pretend you’re sitting in an imaginary chair, or put a real one behind you and touch your butt to it; then stand back up.
• After 20 reps, go back to washing with calf raises until the dishes are done.

Your leg muscles—calves, glutes, and quads—will start to tone after about a week.
