Best Answer: Boxers tend to be loose and shaped like shorts. Briefs are more of a snug fit and have no leg. A compromise between the two styles has been developed, called boxer-briefs that has qualities of both. Boxers are great for feeling some freedom, but briefs are good for keeping support. I like boxers for when I am relaxing but briefs when I run.
If you are going to wear underwear when working out, look for fabrics that are non-abrasive and that have flat seams. Men should wear boxer briefs for sports with medium intensity and jockstraps for high intensity sports.
