Q. Hi Fitz! I'm trim, but I think my back is flabby. I can't stand the way my back fat smooshes out over my properly fitting bras. I know they fit well, because I've been fitted! What do I do for that flab? Karolyn

A. Hi Karolyn. Men want their backs to look like a cobra, and women just want to make sure fat doesn't squoosh over their bra straps. The issue is super common and the fix is quite simple. If you were overweight, I'd tell you to lose the fat first, but you've already told me you're trim. These three exercises will help you develop the muscles casually called "lats." They're quite precise in making your back feel strong firm.

If you don't have Gliding Disks to train with, use paper plates instead! Building strong lats just requires consistent efforts, Karolyn. You might want to try this pull-up workout shown in this second video here as well, shot with Anthony Field of The Wiggles.

Now get to work!
