You could turn fat into fit by running up mountains and punching sides of beef – but that isn't the Stuff way.
Us dedicated gadget fans have a technological solution for everything – and all of these bits of kit let you quantify every bit of health data you can imagine, from your heart rate to your golf swing.
Whether you want to give yourself the edge in competition or shed a few pounds, these electronic coaches will get you fighting fit, but only one of them survived round after round - the triumphant Jawbone UP24.
Winner: Jawbone UP24
Without the willpower to use them, fitness gadgets are about as useful as those unworn running shoes hiding under the bed. The beauty of Jawbone’s Bluetooth-equipped UP24 is that you don’t really need any willpower to use it: you just put it on and it gradually makes you feel guilty about not doing enough exercise. It’s essentially a willpower generator. Seeing how lazy you are turned into numbers, graphs and cold, hard facts on your phone screen will do that. Luckily it alerts you to help you towards your daily goals, plus it’ll work with apps such as MyFitnessPal, Runkeeper and Withings. Oh, and it’s compatible with those trainers too. Just pair them with your legs.

Runner-up: TomTom Multi-Sport Cardio
The latest version of TomTom's triathlon-focused timepiece adds pulse sensors to the strap, opening the door to the zone-based training. It's a great addition to an already impressive feature set that includes dedicated swim, run and cycle modes, and automatic syncing to your phone via Bluetooth. Time to work on that Brownlee impression.

Runner-up: Game Golf
Fairway hounds love nothing more than obsessing over their game’s minutiae, and Game Golf is a brilliant new source of lovely stats. A GPS unit with tags for each of your clubs, it can tell you true distances for each shot, driving accuracy and, like Strava, how your figures compare to the rest of its community.

Runner-up: Polar M400
A cross between a fitness band and a GPS running watch, the M400 a fine all-round exercise buddy. Not only does it gather basic running stats (distance, pace, calories), the accelerometer also tracks your life away from pavement-pounding, including your sleep. It's all wrapped in a very tempting price tag too.
Runner-up: Jabra Sport Pulse Wireless
Heart-rate training usually involves wearing a chest strap or a pulse-sensing watch. But these Bluetooth earbuds offer an innovative third way, taking a reading from your inner ear while piping in your choice of music plus some real-time voice coaching. Use them with the accompanying app and you'll never (unintentionally) veer outside your workout zone again.
