This is an interesting idea, a mobile phone that also helps to keep you fit. It is called miCoach and is being marketed as the latest “must have” accessory for your mobile phone. Basically it monitors your heart rate, tells you how fast you are running and how many calories you are burning during your workout. The device allows you to find your own fitness level and a goal to generate a series of workouts. It also has helpful motivational comments to let you know how you are doing and lets you customise a music playlist to match your workout.
