@JB: agree and disagree. I kind of agree because your core should be worked religiously when doing these lifts, though the lifts themselves. If you hit a sticking point, however, it could easily be because you lack the core strength necessary to move forward. I rarely do either any more because my chiro asked me not to in order to avoid the risk of reinjury (he's an ex powerlifter and works with the D1 college in my hometown), so I feel I should begin supplementing it again. I still do them occasionally but I go very light, and not for any particular reason - I just don't want to be that bitch that never does legs so I'll hit them once every two or three weeks. I have to be careful because they are definitely my strong point and become disproportionally large in a hurry. Deadlifts I like a ton (easily my favorite exercise), but it's virtually impossible to go quite heavy and keep perfect form (i.e. no rounded back). c'est la vie I suppose... And really any excess ab work is usually pointless. edit note: working core a lot doesn't necessarily bring you better abs when you take your shirt off at the beach. I feel it's a performance / health issue to keep a strong one, but for vanity it's kind of a wash for me. I look no better with or without the exercises, but I feel "safer" so to speak having done them so I don't have to go through another 8 months of not being able to stand up straight to walk.
