In time to work off the stress and creeping pounds that often come with the holidays, Trimble and AT and T have announced the availability of the AllSport GPS application that lets users track their exercise activity on select GPS-enabled AT and T wireless phones.

From the handset, the application monitors time, speed, calories burned and distance traveled during outdoor workouts such as running, walking, biking and snowboarding. Users can store workouts to monitor progress, view weekly activity logs, map their favorite routes and share activities with friends.

Through the Trimble Outdoors Web site, subscribers can also:

+ Browse an online library of professional and user-generated trips.

+ Upload and recommend routes and customize trips taken by others.

+ Download maps in topographic, street and aerial views to their wireless phone.

+ Send guided workouts to their phones and "race" against the person who originally uploaded the workout.

"This is a terrific example of how third-party applications are helping our customers get the most from their mobile phones," said Mark Collins, vice president of Consumer Voice and Data Services, AT and T Mobility and Consumer Markets.

"AllSport GPS is an application that is ideal for customers who embrace fitness and want easy-to-use, close-at-hand tools for tracking their goals."

Rich Rudow, managing director, Trimble Outdoors, said: "Now that GPS is becoming a hot feature in cell phones, users are looking for a variety of ways to take advantage of the technology, including using them for fitness and recreation. With AllSport GPS, AT and T customers now have access to a full-featured fitness training application for their GPS cell phones. In combination with the Trimble Outdoors Web site, users can now manage all their content with a simple trip editor or download and experience thousands of professionally created trips. AllSport GPS provides an incredible opportunity for users to plan workouts and monitor their training progress using the cell phone they carry every day."
