I hit the gym after work between 3-4 times per week for cardio & weights (and soon, swimming too!), and I usually go hiking with friends on the weekends. I'll sometimes take walks with neighbors on weeknights as well. All the socializing on the hikes and walks, though, does make me wish my gym allowed non-member friends to join me. I do miss having a workout buddy. :o(
To the numbers issue: I find that the more consistently I exercise, the more consistent my BG is. I suffered from rapid swings and uncertainties with my blood sugar (with regards to exercise) more back when I was first diagnosed a year ago. It can tend to happen still, or course, if I slack off by not working out as regularly. In general, though, things seem to be levelling out these days. :o)
My emotions, however, are another forum entirely!!
