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.

Read on to learn how I accomplished this...

About two weeks ago I pledged to lose weight using my iPhone, AppleTV and Mac. Well, I'm happy to report that I've lost a whopping 6 pounds since then using my iPhone 3GS. Below is a short list of the apps I used as well as a mini-review of each.

LIVESTRONG

This iPhone app has a great feature set for calorie, exercise and weight tracking, although it is not without its problems. Overall, it needs a little "spit and polish." The foods I logged often failed to save correctly when I initially entered them. Instead, I'd have to save them, then go back and edit them in order to adjust time of day, or servings eaten. It wasn't a huge deal, but calorie tracking should be quick and easy to encourage me to keep doing it. If every entry takes twice as long because of editing, well, I'm probably going to give up eventually. Which I did.

In addition, the exercise trackers seem very skewed. LIVESTRONG tells me that a 2-hour bike ride burns about 1,600 calories, while Trailguru gives a much more conservative 750 for the same time and distance. When trying to lose weight, you should overestimate calorie input and underestimate calorie burning in my opinion. I learned pretty quickly to ignore however many calories it said I was burning.

I've struggled with my weight for a long time. In my free-wheeling post-college days I lived with my two best friends, sitting around playing video games, drinking beer and eating Taco Bell. I put on a lot of weight in a short amount of time with that diet and exercise schedule, topping out at 260 pounds. I decided enough was enough, and I strapped on my running shoes, straightened up my eating habits, and lost almost 90 pounds.

In the years that have followed, my weight has gone up and down several times, and I'm at the point now that I need to get serious about losing weight again. According to my BMI, at 6'3" I should top out at 199 pounds, and right now I'm at 225.

This time my weight loss should be easier since I have 3 secret weapons: my iPhone 3GS, my Mac and my AppleTV. Read on for my weight loss plan and how these Apple products will help me achieve my goals.

Since its introduction in May 2006, the look, feel and features of the Nike+ website have undergone relatively minor changes. Which makes the redesign (still in beta) of the site all the more noteworthy. By putting familiar faces in different places, as well as adding some new faces, Nike has added some polish on an already great and revolutionary fitness motivational tool.

When the second generation of iPod touch was announced, one slide on the presentation included built-in support for the Nike+iPod sensor. The cool thing was that you no longer needed the unsightly dongle hanging off your device. The touch just "sees" the Nike sensor and you could add it to the device quite easily. Plus, the app looked great on the bigger screen of the touch, and allowed you to multitask -- not that you should play Dizzy Bee while jogging, OK?

I hadn't thought about it until I got my phone home, but the sensor works just fine with the 3GS. As expected, the app is identical to that on the touch, although Apple posted a tech note regarding answering calls while using the Nike app, something you don't worry about on the touch. If you've never tried using the Nike sensor with either a touch or the iPhone, read on. Oh, and I don't have a Nike remote watch doohickey, but apparently those will work on the 3GS as well. If the Nike thing isn't your bag, we ran down some competitors a while ago.

To pair the device, go to Settings > (in App-specific settings) Nike+iPod and flip the switch to ON. At the bottom (you can see in our gallery) choose either Sensor or Remote, depending on what you've got, and you'll be prompted to move around (sensor) or press a button (remote). That's all there is to it -- the proprietary wireless connection kicks in and pairs the two devices instamagically.

Just like previous iterations of the Nike system, you can change the PowerSong, voice, and units. One new twist: a new Lock Screen pref that will alter the locked-screen display to read in portrait or 2 available landscape modes. Very handy if you have a mount on your treadmill. What, you don't have a mount on your treadmill? Me either.

Now, after pairing, you should have a shiny new app on your screen that has the Nike logo and a plus sign. Unfortunately, my sleepy morning eyes couldn't find the app, but a Spotlight search found it for me. Here's Apple's notes on setting things up.

Keep reading for a short round-up of how the unit works while running.

As promised, we're launching a new series called Road Tested where we try out various products for a month or more, see how they hold up to extended "real world" use, and report back our findings. To kick things off we're looking at the EcoRunner from Marware [thanks to our friends at Dr. Bott for the review unit].

The EcoRunner is a "green" product in that the primary material is not neoprene, but "a revolutionary environmentally friendly material." I'm not sure what that is, but I can say I like it better than neoprene -- it feels just as soft, but the cells are smaller and thus the material is more supple. The EcoRunner can be worn on the wrist or arm (using an extender strap, included) and is designed for the 4th-gen iPod nano. There's the requisite vinyl window for controlling playback and viewing the screen, plus the case can be used with the Nike+ Sport kit attached (there's a strap to keep everything in).

Does it work? Well, there's one caveat to our test: we used a 1st-gen nano, the white model that was infamous for being easily scratched. It's increasingly tough to find cases for this model, but we found the EcoRunner is stretchy enough to accommodate the slightly thicker model. The side effect of this, possibly due to thickness or the more squarish design: the vinyl window busted (see gallery), leaving the unit exposed and capable of falling out. Call it a "stress test." It's definitely a design challenge to secure the vinyl in a way that won't get too stressed, especially in cases where everything else is so stretchy.

The softness of the case can't be understated. It is really smooth and lightweight and stretchy. I'm partial to wrist straps, because I tend to skip around my playlists depending on my workout. If you find yourself monkeying with your nano during a workout, this is a terrific wrist strap. The extension strap to use it on your arm adds virtually no weight, and holds up well, but bulging biceps might strain that window. The Velcro used is very high quality, but the stitching on the end can sometimes be a little tricky to thread through the grommet -- so I recommend not removing it entirely. Just pull it off your wrist. One upside is that you can charge the nano in the case, so the entire unit becomes home to your nano. If you only use your nano for working out, you'll never have to remove it from the case.

After a month (OK, nearly 2 months) of solid use -- we're talking about near-daily use on the treadmill and at the gym -- the EcoRunner holds up well. As I said, using a 1st-gen nano isn't recommended by us or the manufacturer, so I don't know if the thinner nanos would bust the window after prolonged use. Other than that, there's very little visible wear-and-tear, and I'd recommend this especially if you a) prefer your nano on your wrist, and b) need a case that'll hold the Nike+ Sport kit. Your choices are pretty limited when it comes to both of those criteria, but the EcoRunner is a good bet either way. If you've had experience with this particular model, let us know in the comments.

UPDATE: Great questions in the comments! As far as sweat retention, since my wrist doesn't sweat too much, I'd have to say no problems there. You might have an issue with a very sweaty bicep, but I feel the material's tighter cells (as opposed the larger, more open cells found in neoprene) would guard pretty well against this. There's no signs of staining, either.

The extender strap adds a little over 6 inches to the overall strap length. Total that's 11.5 inches (see added gallery image). My puny biceps fit fine, but if you have some massive guns then yeah, you might have a problem.

Ahhhh, New Year's resolutions. You promise that you're going to take better care of yourself, improve your life, and then you usually break all of those resolutions by January 2nd. This year's going to be different, right? Here are some gift ideas to help you keep your 2009 New Year's resolutions.

Weight Loss

Unless you're the lean and mean marathon Mac man and real-life action figure Adam Engst, you could probably afford to lose some weight. Resolving to lose a few pounds is a classic New Year's resolution, and one that's very easy to break. Fortunately, there are some Mac and iPhone applications that can help you to stay the course:

CalorieKing Nutrition & Exercise Manager for Mac OS X -- This US$45.00 application has a huge food database and makes it simple to drag-and-drop caloric information into a food diary. Exercise tracking and a weight log are included as well.

BeFit -- TUAW covered the debut of this US$15.95 Mac application earlier this year, and it remains a good program for tracking what you put in your mouth. Remember, you can get BeFit at half-price if you're a current Jon Brown Designs customer.

In early September, TUAW published an article about iPhone exercise-tracking apps that use the built-in GPS of the iPhone 3G to track walks, hikes, runs, and bike rides. One of the apps, RunKeeper, provided instantaneous feedback of speed through a bar chart display and had a $9.99 price point.

Jason Jacobs of Fitness Keeper, the developers of RunKeeper, announced yesterday that the company is going to make the application available for free in the App Store (click opens iTunes). As noted in Jason's email, "Although we have been featured recently in TechCrunch and NY Times (and TUAW, of course!), and we have several thousand paying customers and a vibrant community, we are making a bold move and making the app free. We are doing so in order to forgo short-term revenues with the hope that our community will get to massive scale."

Fitness Keeper definitely listens to user feedback -- our September post mentioned that RunKeeper didn't track total rise or elevation vs. speed, and now both of these items are available on the tracking Web site.

Please note that Apple must approve Fitness Keeper's price change request before the new pricing goes into effect.

Dedicated runners, bikers, hikers, and walkers like to keep track of their efforts, dutifully logging miles (or kilometers), time, weather conditions, elevation gain or loss. That's why there was a lot of excitement after the Nike + iPod Sport Kit was announced in 2006, since the same device you were using to listen to music could be used to tell you just how far and fast you ran.

Unfortunately, many competitive runners quickly realized that the accuracy of the Nike + iPod Sport Kit wasn't all that great. TidBITS Publisher and marathoner Adam Engst wrote a post last year in which he pointed out how inaccurate the Sport Kit is, even when carefully calibrated. Adam thought that the Sport Kit had some possibilities for fitness runners, but not for those who need accurate measurements of distance and time.

When the iPhone 3G arrived this summer, I wondered how it would work as an exercise tracking tool. After all, the device has GPS built in and should be able to accurately measure distances, time, and even elevation. I looked at

• Trailguru
• RunKeeper
• The Running GyPSy
• iTrail

To see how these apps and the Nike + iPod Sport Kit compete, read on.

Since January of 2007, Montebello Software has shipped Ascent, an application that analyzes data from exercise computers. If that exercise computer has built-in GPS, the analysis includes a plot (static or animated) of exercise paths over satellite, topographic, or street maps.

Version 1.9.4 of Ascent now includes automatic syncing with Garmin Edge 605/705 cycling computers, drag and drop importing of .gpx, .tcx, or Polar .hrm files, and the ability to split or combine activities. I've been considering a Garmin Colorado for geocaching, and found that it syncs directly with Ascent. That may actually get me off my rear end and onto my bike again, since I can now do something with all of that ride data! Runners and hikers will also find Ascent to be useful.

A function-limited trial download is available, or you can purchase a full license for $40.

You're one of those crazy people who enjoys working out ... and reads tech blogs. It could happen. You've got the Nike+ sport kit and lots of great Nike Sport Music [iTunes link]. What else could you need?

How about free workout videos? Lifehacker points out a series of four free workout videos from Men's Health, optimized for the iPod. Take your pick of

• The at-home muscle plan
• The Marine Corps workout
• Pack on muscle like a pro
• The ultimate strength-boosting workout

Once you've downloaded* the videos, either double-click the files or just drop them into iTunes. Now you're ready to get pumped!

*A free registration is required or, as LH mentions, just click your browser's stop button before the page loads completely and you'll see all the download links. You're welcome.

When you're horribly out of shape (like I am) and are trying to get fit (like I am) you need something to spice up those long hours in the gym. This article suggests that an iPod might be the perfect gym companion, and virtual trainer. The article speaks to a few people who have downloaded 'personal trainers' to their iPods that give them encouragement as they work out.

Strangely the article does not mention the Nike + iPod Sport Kit, which is designed to do just what this article suggests. I'll be getting myself an iPod nano, and a sports kit, after the Sept 12th event (just to be sure, you never know) and I'll report on my experiences as a fat man with a sensor in his shoe.

TrailRunner is a neat application that turns any iPod into a workout planning machine, in a way. The application allows you to interactively plan a route, whether it be for running, inline skating, bicycling or what have you, and export those directions to your iPod. This way you'll never be lost on a workout again (I avoid that problem by never working out).

TrailRunner suggests a donation of 21 €.
