when to do dead lifts??

[B.E.N.]

I understand your practice what you preach mentality and respect it.
But who is to say the dude doesnt know what hes talking about because his methods are different?

I haven't fully understood the purpose of deadlifts. If they are just for the lower back. I really don't concentrate on the lower back. There are also stiff-leg and regular deadlifts. I thought one hit the back and the other the hamstrings.
