Tried and tested:
Fitbit Flex, £79.99
The Fitbit Flex wristband wirelessly links to your iPhone (when you download the app) and via a dongle to your laptop or computer, easily updating your progress online. It tracks your steps taken, calories burned (based on the stats you input when you start), hours slept, distance travelled, active minutes and quality of sleep making it pretty conclusive. Annoyingly you cant see your daily progress on the band - you need to be on your computer or app - however lights on the band go from 1 through to 5 (5 lights means you have reached your target for the day). At £79.99 its good value.
Nike+ Fuelband, £129
Nikes Fuelband tracks your steps taken and tells the time. It also gives you daily Fuel points. These points are gained the more activity you do. The points are universal so you can compare with your friends or partner regardless of your height or weight good if youre competitive. Whats handy is you can see your stats via an LED screen on the band so you dont need to check the app to see your progress. Considering the Fuelband doesnt track your sleep the battery life isnt as long as other bands that do more, you need to charge this every three days or so.
Jawbone Up, £99.99
The wristband, endorsed by Gwyneth Paltrow, looks stylish and tracks a lot - steps, calories burned, active minutes, idle minutes, active calorie burn and resting calorie burn. It also tracks your sleep pattern. The clever Up can even wake you up with a vibration (within a window of time you set) when youre at your lightest sleep. Additionally you can set an Idle Alert for your wristband to vibrate at intervals throughout the day to remind you to get up and walk around (great if youre deskbound). Although, were not sure how accurate that alert is, since during a bout of sit-ups at the gym the wristband vibrated! You can also log your daily food intake on the app (if you can be bothered). The app, over time, helps you identify patterns in your life such as how sleep quality affects energy levels and offers regular reminders that relate to you. One downside: there is no screen or lights to show your progress at a glance.
Full Fitness App, £1.49
If, after disembarking the treadmill, you struggle in the gym then this app is for you. It is pre-programmed with different workout programs for you to at the gym such as Complete Body Workout and Body Toning for Women each exercise comes with images and/or videos to show you how to get it right whether its using free weights or gym equipment. There are also tons of exercises that you can wade through and the app allows you to build your own programs. Other features include weight and measurements trackers, calorie counter and the ability to share your workouts with friends. Its like having a personal trainer in your phone but at a fraction of the price.
