Recently got back into the sport after about a 8 yr break; but I did stay with the sport on the couch. Anyhow, hit the track really hard last week trying to catch those fast kids on the 80s. Noticed my lower and mid back sore the next few days. I used to wear a kidney belt back in the day. I'm gonna buy one today, but I was wondering if anybody still wears 'em. Seems like the pros abandon them or put them on under their jersey. What gives? You guys wearing the girdle?
