I love the iPod nano for working out because it's small enough to bring to the gym and it doesn't get in the way. In fact, I usually just tuck mine in a small leather case an toss it into my pocket. The problem is that having your iPod in a pocket requires you to take it out to change songs/volume, etc. Also there's the risk that it was either fall out or be crushed if it's in a back pocket.

My solution was to grab an arm band for it - the XtremeMac SportWrap (US$30) fit the bill perfectly.

The SportWrap is a neoprene case the wraps around the iPod nano and leaves access to the scroll wheel and screen (although both are covered by a clear, protective membrane) so that you can operate them on your arm. It comes with two different sizes of arm straps to fit everyone from Lindsay Lohan to Hulk Hogan. Although its adequate to keep it connected to arm, I wish that the SportWrap has a bit more Velcro on the flap end of the strap.

I use my iPod upside-down when strapped to my arm because it's a little more natural to read the display, but either way, it takes a little getting used to. I suggest starting your workout or running playlist before strapping it to your arm.

One of the surprises with the SportWrap is that it can easily be used while doing a bicep workout - something I wasn't sure about. As long as you attach it high enough on your bicep, i.e. above the peak, your able to do most arm exercises without a problem. Another nice feature is that it is water-resistant. I sweat pretty good last night at the gym and my nano was no worse for wear.

The XtremeMac SportWrap is comfortable, easy to use and recommended for anyone who lifts, runs or bikes with their iPod. It's available in black (pictured), purple for the iPod nano or mini for US$30 from XtremeMac.
