Support is important! I had a good friend in high school twist a testicle during football practice. He did not get hit at all, it was just a conditioning day after a game. He got checked out at the local hospital and they took him by ambulance to lager hospital 35 minutes away. He had to be rushed into surgery to untwist it! The Dr. told him if he had waited another 45 minutes or so they would have had to take it!
That being said I wear boxers every day. The freedom of commando w/o the direct junk-on-jeans action.
I don't want skid marks inside my jeans. Commando is OK for bicyclists using the proper bicycling shorts, but other than that, it's tacky. This is coming from a man that wants support and hates having his equipment bouncing around. Formerly "whitey tighties", now they come in dark colors (which helped me at the office one day, forgot to zip back up and nobody noticed).
This kind of discussion has cropped up before, you'll see a full range of responses. That's the long and the short of it.
I once broke my leg. The paramedics ended up cutting off my shorts. I'm really glad I wasn't going commando.(DId i mention that this was on the side of a busy road?) I now try to avoid commando whenever possible.
I currently use boxer-briefs. I wish I could find a happy medium between briefs and boxer-briefs that did not give me wedgies and yet separated the boys so they don't get stuck to my leg as the day wears on.
"Thanks, but a built-in HIIT program (like Sprint 8) changes the machine's speed and elevation automatically as you move through the sprints and recovery intervals.
That is what I am looking for (with the HIIT intervals timer).
