With FitnessBuilder ($19.99, available here) for the iPhone and iPod touch, iPumpOne aims to make the need for a personal trainer obsolete. That's because the app places a library of exercise and workout images and videos right in the palm of your hand. The software features over 400 complete workouts and a growing collection of over 4,000 exercise images and videos that users can drag and drop to create their own workouts.
