Exercise repetitions to loose weight on thighs?

Doing all those squats and lunges will grow the muscles in your thighs and make them larger. To lose weight, you need to eat a proper diet and do lots of cardio. I know that's not what you wanna hear, but that's how it is. If you really wanna take the unpleasant route and try to lose weight through squats and lunges, you need to do 20+ repetitions of each for at least 40 minutes. You will not be able to walk properly and be in constant pain throughout the duration of this sadistic exercise regimen - you're better off running, biking or swimming.
