With the new year approaching, managing your health has probably been added to your list of resolutions. As an entrepreneur, you can be working any time of the day or night. You try hard to squeeze in a workout when you can. But when crunch time comes, it's easy to lose track of time and your fitness regimen.

With the best of intentions, you plan to do your workout first thing in the morning. But a business priority comes up that moves it to the afternoon. The afternoon hours slip by because of another high-priority task. And before you know it, the evening has come and gone, and you haven't had a workout.

When entrepreneurial tasks call to you from every corner of your business, your hours blend into one another and days go by with little attention to your fitness goals. Wouldn't it be nice if you had some way of tracking your fitness activities and goals so you could stay on top of them? Chances are you use web analytics for your website. Why not use analytics to track your health and fitness?

Everything that can be measured can be managed. Here are some simple and fun ways to track your health and wellness activities. Once you see the data, you can honestly assess how well you are doing. And you'll be motivated to make improvements.

Nike+ iPod/iPhone Sport Kit ($29): This kit includes a sensor and an iPod adapter. The sensor goes into your running shoe. Nike sells Nike+ shoes that have a pocket especially designed for this sensor. People have used the sensors on non-Nike+ shoes as well. The adapter connects to your iPod Nano. IPhone 3GS and iPod Touch do not need the adapter. If you are into running, this kit is a good, simple way of tracking your runs and challenging your friends. You can upload your data to nikeplus.com to create a journal of your runs and start training for future runs.

Fit Bit is a tracking device that monitors your fitness and sleep. The device has a motion sensor similar to Nintendo Wii that can pick up your motions in three dimensions. It claims to measure various aspects of your activities, including intensity, duration, steps taken and calories burned. In addition, it can track the quality of your sleep: how much you slept and how many times you woke up during the night. The device comes with a base station that will wirelessly and automatically upload your data if you are within 15 feet of it. It sells for $99. The company started taking orders at the end of last year but has had problems with fulfillment. We hear the product is shipping now, but the company has a backlog.

Run Keeper: This is a great iPhone app that keeps track of your activity and creates a workout history. You can also share your activities with others. It works off the iPhone GPS. You have to start and stop it manually, and it provides stats for your run and a handful of other activities. The basic version is free, and the Run Keeper Pro sells for $9.99.

Zeo is a sleep-monitoring system that works off your brain waves. It consists of a headband and a bedside display that looks like an alarm clock. You wear the headband to bed. It has three sensors that monitor your brain waves and send the data to the bedside display. The bedside display has an SD card that you take out and plug into a PC or a Mac to upload the data to the Zeo website. Zeo has online tools that allow you to analyze your sleep and create charts and journals. The base model goes for $249. A bundle that includes guided coaching goes for $349.

Bodybugg is an armband that claims to track calories burned. The armband has four sensors that measure motion, heat flux, sweat and skin temperature. You also can get a digital display that looks like a sports watch that connects wirelessly with the armband and shows your data real time. You would upload the data from the armband to your computer and to Bodybugg's website. You can also manually enter your food intake. The online system can analyze your calorie intake and output. Bodybugg is only available through 24 Hour Fitness and Apex Fitness.

Virgin Health Miles: This is a service offered by gyms or employers. If your gym or your company offers this service, you join by first buying a pedometer, called Go Zone. The pedometer tracks your walking/running activity. You upload your data to the Health Zone website. There's also a kiosk, called Health Zone, that can track your weight, blood pressure and body fat. There are two subscription services. The basic version is free, and the premium version costs $9.99 a month. For additional motivation, you get Health Miles as you increase your fitness level and reach your goals. A similar service, ICount, is available from WalkStyles.

Many other devices and applications can help you stay in shape and manage your health. For mobile devices alone: iPhone has more than 2,400 mobile health and fitness apps. Android Market has about 320, and Blackberry World has a little more than 100.

Gotcha's: Simplicity and practicality are key to making these work. You have to figure out which apps or devices fit your lifestyle. For example, the Zoe device is interesting, but wearing a headband at night might be best if you're alone. With any device, you have to realize that you need to carry it with you.

Bottom line: Monitoring your activity is a great way to get started on managing your health and fitness. With so many options on the market, you can find one that meets your needs. Managing your health can be as precise, data-intensive and results-oriented as managing your business.
