For reasons I don't want to list, I haven't done squats in years. Recently, I have started doing these lever front squats (I can't post links, but its on exrx.net. It is the same movement as a squat, but the weight is more distributed on your shoulders and a "forward" angle compared to regular squats).
How much less effective are those than regular squats?
I also do deadlifts.
Thanks in advance.
