If you have swole quads, you need to figure out your waist to thigh ratio. Take a measurement of your waist (relaxed, just below your belly button), and your thigh (right under buttocks, flexed). Half your thigh measurement. Then you'll have your waist/thigh ratio. Look for jeans which offer a lower ratio than you need.
