Suunto's heart rate monitoring system is said to lead to more effective results and higher overall satisfaction for members.

The new Suunto Fitness Solution system is designed for use in group exercise and cardio training environments.

It shows up to 72 participants' heart rates simultaneously in real-time in the class, either through a PC in front of the instructor or projected on the wall.

The colour-coded training zones - light blue for low heart rates, green for medium and red for high - inform the instructor on individuals' fitness levels.

The instructor is then able to guide members and adjust the session accordingly.

At the end of each class, the system automatically generates members' personal performance reports with summary data.
