Fit is the new skinny. Just ask Rebecca Black (no, not the Friday girl). Black is a national fitness model and the owner and personal trainer of Bexa Body Fitness in Westerville. She has her own interesting weight loss, health gain story, and she’ll probably tell you about it today if you ask nicely. Black is guest bartending at Camelot Cellars this evening from 6 to 9 p.m. I hope someone who has had one too many glasses of pinot challenges her to a push-up off. I also hope the event raises a lot of money for Dress for Success Columbus, which proceeds of tonight will go toward. Grab a glass from the pretty lady after you hit up the Short North Summer Sale.
