My primary lifts are usually squats, but... for hitting the quads what does everyone prefer? Belt Squat or Leg Press or Hack Squats
I just bought the westside ATP belt squat machine, but I still love my basic little hack squat machine for hitting quads. What is everyone's favorite machine and exercise(s) to hit the quads?

As I mentioned I like the hack squat to do hack squats and also sissy squats. My favorite uses for the belt squat are hip-loaded calf raises (donkey) and simply walking (for the hips).
