Fitness start-ups flex muscles
Fitness technology promises to be the next big boom for start-ups
My trainer is taking me through a new routine, dipping low into a squat jump and up again. "Keep those reps up!"
This is not a normal living-room workout or an outdated fitness DVD. A heartbeat tracker, strapped to my chest, pips along to my progress. My calorie burn appears on screen, and reps (repetitions) add up as a notification on the TV screams: "New personal best!" My smartphone tabulates the data and ranks my performance.
