This may be a ridiculous question but here it goes: I seem to get nasty DOMS in my hamstrings (particularly after doing RDL's), but I don't suffer it anywhere else. After squats or deads I may feel tired, and maybe slightly sore the next day but it's minor, and definitely gone the next day. However after I do RDL's my hamstrings are wrecked for days. I last did them on Friday, and they are still tight as hell and sore. Is it particular to hamstrings (I know, ridiculous) or is it just mine are weaker then normal? Thanks for any feedback.
