Squats, glute bridges. I recommend doing leg raises to the side between the squats. Also when you're doing glute bridges, when you raise your hips press your knees together. Doing these exercises you train your thighs front, back, sides and insides. Good luck

Personally, I believe lunges are the best. Lunges really make me feel the burn of ezcersizomg my thighs when most others don't. Same with riding quickly on my Ripstik
