Hack Squats

The hack squat machine is without doubt the king of all weight machines. Every self-respecting gym must have a hack squat, as it is the best quadriceps building exercise that exists. No other squat or leg press machines can replace the hack squat. The best hack squats have an angle of about 45° and must be plate loaded. The feet plate must be big enough (about 80 x 80 cm), have a rough surface against slipping, and preferably have an adjustable angle. The success of the hack squat is its simplicity.
