As I was looking through the recent Dover catalog, I saw a contraption called "shoulders back" - apparently some type of vest that riders can wear to help ensure proper posture?
Has anyone tried such a device and if so does it work?
I've developed terrible posture from slouching over a computer for the last 15 years. I've been doing all kinds of exercises on a daily basis to improve my posture but even when I think I'm sitting in perfect alignment my instructor swears I'm still slouching. So I'm considering ordering this product but don't want to waste money on something that doesn't work.
