Several online communities allow you to track your progress along with others using online databases. Sites vary in the depth of their database-driven features, fields available, quality of the user interface, reporting options, and pricing plans. Take a close look before you sign on. It takes a significant commitment to work out, and an even greater commitment to record every calorie and push up.

ActiveBody (free) offers a solid relational database for cycling, running, swimming, walking, and gym workouts, including customizable fitness routines. You can build your own reference tables for items such as "swim stroke type," "pool type," and "swimsuit," allowing you to discern whether the Speedo LZR Racer actually makes you faster. Similar reference tables are available for the other supported activities. The site supports individuals and teams and provides reports on body metrics, distance/time completed, and other useful reports.

introPLAY (free) tracks your hours sleeping, working, and training; your happiness, stress, energy, and soreness; weight, resting heart rate, body fat, number of cigarettes, and alcoholic drinks; and other vitals that you care to enter. Log your exercises into the database to compare with others and receive "trophies" for reaching various milestones.
