Regarding the back pain, I'm really surprised at how weak my core is, since doing the training specifically targeting the core. I've had lower back issues all of my adult life and I think that a weak core may be the issue.
I wouldn't have guessed this about myself. I walk daily and do yard work, etc. My job occasionally requires some vigorous activity, so I'm no couch potato, still in core strength exercises I'm weak. Maybe the lower back pain is a result of a more vigorous lifestyle, bolstered by the weight loss, but without (at that time) the corresponding increase in core strength?
My trainer is constantly giving me tips on how to avoid injuring my lower back when telling me how to do this exercise or that. Without that guidance, I'd be certain to throw it out of whack.
In terms of the date... I'd define the terms a bit more. My experiences with dating co-workers echo eck's assertion. If it goes poorly it's uncomfortable.
