constant tension. stop squats 3 to 4 inches below lockout and hold between reps for 3 to 5 seconds. leg press (single and double leg), do the same. single leg db squats do the same. try it and watch the growth happen. i dont go over 175 on the squat or 4 plates total on the leg press and the pain is through the roof. dont comment on its effectiveness till you try it. also, check out tom venuto's quad blaster apparatus for a jacked up version of roman chair squats that wont allow lockout - mindnumbingly painful.
