So usually I just squat with a free-weight barbell. But all those stations were taken up, so I had to use one of those squat stations where the barbell is attached to the rack. It looks like this: http://img298.imageshack.us/img298/6510/exercise185055826616em.jpg As I was squatting it seemed just as hard as usual. But after my legs didn't seem as worked out as usual. Is it just in my head or does using one of these stations make a considerable difference? The reason I ask is because I liked it since it forced me to keep perfect form. But I don't like it if it's not nearly as good of a workout.
