Around here, we're fans of The Biggest Loser. While we might not always agree with everything the trainers say, one thing that's tough to dispute is that having the right equipment can go a long way toward staying motivated. Just imagine trying to complete a long run without rocking out to your favorite playlist!

A few weeks ago, The Biggest Loser featured the Motorola MOTOROKR S9-HD headset (check out the video right here), which is a device that allows you to listen to music (or a workout) via Bluetooth while taking hands-free calls from most Bluetooth-enabled cell phones so you won't miss that call about the race coming up next weekend.

The S9-HD wireless stereo headphones offer high-def surround sound with noise-isolating ear buds. Plus, from a girlier standpoint, it goes around the back of your head, low enough that it shouldn't interfere with your ponytail. It also goes over your ears, so it won't slip or move out of place even during the most grueling workout. But it gets even cooler.

Now, you can go to NBC, where The Biggest Loser and Motorola are teaming up to give you the opportunity to get advice straight from trainers Jillian Michaels and Bob Harper -- you can download a series of podcasts telling you how to be a big loser!

Want your own S9-HD? You can buy it here (including a free iPod adapter) for $129.99. But, keep checking back, because we'll be giving away one of these beauties right here at That's Fit in the coming weeks -- and you could be a big winner!
