Well, even without using any weight, if my feet are close together at all then when I start to go down I get sharp pain in the front of my hips. I know that I could just widen my stance, but I would also like to solve the problem.
Casual hardgainer magazine has been preaching similar methods for over a decade. There are thousands of people that have prospered from such a routine.
If I had no flexibility problems, I would do the full range squat and trapbar deadlift.
