THE BASICS: Nike+ lets athletes log runs and workouts (using Nike fitness products, of course) and connect with others of similar ability. With new training modules, it has expanded to include metrics for basketball players, gym-goers, and even moms and dads looking to get more active.
COST: Free with purchase of a Nike SportWatch ($170), FuelBand ($150), or other compatible device.
SOCIAL SKILLS: Virtual running groups abound, you can compete against others on a leaderboard, and an Xbox feature lets you train remotely with friends in real time.
BEST FOR: Finding training partners and new routes, especially if you're a runner. Based on your history and workout log, Nike+ suggests similar places for you to run and people to run with.
