I might be the only person not rocking a Fitbit nowadays. But after watching the brand's first-ever 60-second TV spot, that could change. The ad begins by following sporty men and women tracking typical running workouts. Things get extreme fast, with a man scaling a large boulder -- sans rope, but with Fitbit. This little gadget can track the movements of a lovey-dovey powerlifting couple, a paddleboarder, ping-pong players, a skydiver, or just someone aggressively running up a flight of stairs with groceries. "Find your fit" closes the ad, seen here, and created by Argonaut. Daniel and Katine Mercadante directed. And that voice in the ad is Brett Anderson, lead singer of The Donnas.
