So whenever I dead lift (standard, sumo, straight leg) my hamstrings are excessively sore for a few days. I can squat heavy with no problems but if I a do D/L's I limp around like an old man. I am sure I am a little tight in the hamstrings but I do stretch and do stuff I see on the mobility WOD. My general mobility isn't that bad I can squat to the ground easily and in good form and I am more limber then anyone I know. I have gone through times of D/Ling around twice a week to see if it would help but it didn't seem to. When I do D/L I am doing it in a 5x5 program so I am not going to my max every time or anything.
So what's up why do my hamstrings hurt so much?
Is this normal?
Is there a lifting program that may address this?
