For the most part, I've been disappointed with iPhone fitness applications. I'm not talking about Nike+ but rather the third party apps found in the Health & Fitness section of the App Store.

Apps that track your routes tend to be battery-killers (not really their fault, more due to the way the SDK insists they work). The ones that create exercise playlists depend on time-exhausting Mac-based solutions that have to analyze your iTunes tracks for their beats-per-minutes, creating a heavy investment with a minimal payoff. Genius on the iPhone does a decent job, without that time commitment.

I don't quite get the food and exercise logging apps -- I find that it's simpler to do all that on my primary Mac, using a physical notebook (you know: paper, pen, old tech) when I'm on the go. As for the stretching and exercise guides, I find them awkward. I'd rather use a DVD or a Wii-based game (I adore Gold Gym's Cardio Boxing, for example) where I don't have to keep referring to a 4-inch screen all the time and the sound is clear, and the instructions are easier to follow.

So what am I missing here? What are the really good iPhone-based fitness apps? I feel like all the ones I've tried just keep missing the point: to make exercise better or funner(™ Apple). Yes, they make exercise more portable, but do they provide a better win over Nike+, a bike computer or a garmin?

Please do chime in in the comments. Let me know what iPhone Apps I have been missing, and which ones will improve my exercise experience, whether in the home or on the jogging path. Surely, there have to be some winners out there, and I'd love to hear about which apps are working for you, and why.

Earlier this month, I wrote about connecting my old Mac mini to my television . My mini offers a great Apple TV-style lifestyle with none of the Apple TV limitations. It's a real Mac running real Snow Leopard, albeit on an older, admittedly limited mini. I have Front Row, EyeTV, QuickTime, and more, all ready to entertain me on demand, as well as standard system access to mail, web browsing, etc.

The sound in my living room is powered by a couple of speakers that shipped with an ancient computer monitor. Their audio works fine for close-up TV watching and Wii playing. Move across the room and those speakers prove how limited they are. Add in a treadmill with its motor noises, and the sound decreases to virtually nothing.

So how can one listen to those great shows that are playing back on that lovely large screen across the room, especially when walking or jogging on the treadmill? I messed around with several solutions until I stumbled across one that really worked well for me. Using my home's 802.11g Wi-Fi network, I could call my iPhone from my Mac using Skype. With only the most minimal of lags, I was able to transmit live audio and watch my favorite shows on the Mac while listening on the iPhone from my treadmill.
