@pdbcm 38F. I've been in CrossFit for 2 years, 3 months. I've slowly/steadily gained weight in my 30s, but I've gained ~15lbs since I've been in Crossfit, gone up a size in shirts (damn lats!), and 2-3 sizes in pants (mostly my ass). About a year ago I started replacing most of my wardrobe. I think weight changes have stabilized...god I hope so.
(When I started CrossFit I aimed to lose 10-15 lbs...ha! I've resolved that's...not happening...).
I've made some loose efforts to increase protein intake and reduce alcohol, but overall haven't made major dietary or nutritional changes.
I look at the scale far less, in part because my weight seems to vary much more dramatically. A big weights day will cause swelling and higher weights for 2-3 days. It confuses me.
BUT, I'm far more confident in my body and I look better in the mirror. I think if prior-to-CrossFit me saw a photo of me now...I would absolutely not believe I weigh more.
