see, with my routine, i do deads and hypers day after i squat - that's the only way i can get so many heavy days in a week.
also, the whole exercise in itself feels too harsh on my poor lower back (i feel more comfortable with deads). plus, it seems you only get about 3-4 inches in the whole range of motion where there is hard work for your hams. the rest is just extra punishment on the back and joints. any advice (other than to do the exercise correctly... push butt back, etc)?
