If sweat isn’t enough to prove a good workout, TrainingPeaks offers a way for the fitness-obsessed to get detailed rundowns of their athletic feats. The Lafayette-based company serves pro athletes and recreational gym rats alike with play-by-plays of their performances—everything from lap split times to creating a workout schedule.

Here’s how it works: Sync almost any monitoring device (like a Timex heart-rate monitor) with the program (the basic consumer plan is free); do your running intervals; then log on to trainingpeaks.com and instantly see your metrics.
