Measuring what you do really works great as a motivator! While reading The 4-Hour Body I decided on much more actively tracking my workouts by using RunKeeper + iPhone 4, Ant + and a Garmin heart measuring device. It´s great! Bellow is a picture of how all this data is logged in RunKeeper by using their application on an iPhone 4.
Just to clarify, Ant + and the Garmin belt can be purchased from Whaoo Fitness and it was slightly confusing what was what in regards to this equipment. Instead of purchasing the equipment on Amazon I decided to buy it straight from their website which worked well. For some reason i managed to pick the Wahoo Fitness Pack 2 instead of 1 which is a mistake. I recommend getting the armband as having the equipment around your waste when running is not comfortable. So get Wahoo Fitness Pack 1. Download the RunKeeper app from the appstore and make a profile. Once you have done this you are able to sync you account with Facebook so you can post your activities directly to your wall and see if some of your friends are using RunKeeper. With the Elite account you get a full featured RunKeeper account that I have just started trying out.
To sum up take care of yourself so you can take care of your business.
