I love them.  Kind of.  At least seem to like them way more now than I ever have, which is possibly because I wasn't able to do them for so long.  Either way, they are back and I'm having so much fun...minus the part where 170 feels like 400lbs on my back, but hey.  I still have to be smart, because there are definitely times where I can feel instability and weakness/pain seeping through, and I address accordingly.  Usually by stopping immediately and doing some ab work to correct/compensate for my anterior pelvic tilt, which could very well be the culprit to all of my problems...along with a wicked tight piriformis.  ANYWAY.
