Hey, I exercise 4-5 times a week at my local gym...and really enjoy it. I started up again a year ago this past April and haven't lost an ounce! (Gram? hahaha) Maybe I am not working hard enough...and that is why it is so enjoyable?! eriously, I find I am much better cardiovascular wise...and I took up weight lifting mid March and have had to up my weights so I must be getting stronger! I've goofed off this past week though...
What I was going to say is, even if I don't lose weight from exercise alone (diet is a big componant, and maybe this is just a cop out, butt I don't like drinking alone so my only vice to cope with this long distance relationship is by indulging in carbs and chocolate!) I feel stronger, healthier, more vital and energetic...and that is a good thing irregardless if I were underweight, "normal" weight or overweight!
Plus, exercising always helps me to cope with missing my honey...I just turn my walkman up REALLY loud and bebop along...
Anyway...glad to hear you're having a positive experience!
