HR Zone Trainer helps you to focus on indoor training when on your turbo trainer or other home training equipment.
Looking at your small Polar HRM readout is no fun and holding efforts can be difficult. HR Zone Trainer tries to help by giving you a time-line of how long you have been working and how long you have left to go. Your workout history is saved so you can analyse your saved data at will.
Use a Polar HRM with the SparkFun HRMI
to interface your HRM with your PC.
Then load a predefined workout, click start and try to keep your heart rate in the specified zone.
