I herniated mine july 1st doing suspended goodmornings. I herniated L4/L5 and to a lessor extent L5/L6. I finally started squatting again two weeks ago and my back is feeling good.
I took the first 5-6 weeks off of legs entirely and then started doing leg presses, leg ext and leg curls as they didn't aggravate my back. When my back felt good again I started squatting, first week was fairly light and the second week I did a reg squat routine going up to a 1 rm. I haven't done deads yet as I'll wait another month to do those but so far so good.
