In some ways that's a good thing, i get there before it gets especially crowded, and leave about the point there's a ton of people climbing. On the other hand, that means i miss out on a lot of the buff eye candy *cough*.
But anyways, my schedule for exercisey days seems to have become leave work at 4, get to gym about 5, spend 30-40 minutes climbing, spend 20-40 minutes on the pull-up machine, spend 45-60 minutes on the cross trainer machine. So with the changing clothes and a couple short breaks that generally means leaving sometime between 7 and 7:30. Get to the mall 15 minutes after that, wander around for a bit, then get dinner at Daphne's. (Which is either 900 or 1200 calories, depending on if i get the fire feta or not, but that's calculated as part of my regular daily diet, it's not bonus stuff for going to the gym.) And then generally get home sometime between 8:30 and 9.
If i can believe the cross trainer machine's math i generally burn 800-900 calories on it, though i eat probably about 100 calories of "sport" (ie caffeinated) jelly beans, so it's a net gain of 700-800. That should mean that all else being equal, about every four trips to the gym equals one pound of fat lost. Of course biological math never works out that neatly in reality =P
