The Tanita CJ688 Calorie Jump health monitor is a great piece of equipment for getting you fit and losing weight. The skipping rope will count your every jump and calculate the calories you burn doing so. It uses your weight to provide more precise calories readings so you can stay up to date on the progress of your session, and it works for forwards, backwards and 'criss-cross' skipping. This device is light and it turns quickly so you can maximise workouts, and it is made using plastic that is both strong and doesn't twist. Adjust the length of the cord to suit your height and see jumps and revolutions displayed up to 9999 and calories to 4108.
