Launched in 2006, the Activio Fitness System is the company's group exercise solution: a large screen at the front of the class showing a heart rate 'dial' for each class participant, all of whom wear chest belts, with heart rate data transmitted wirelessly and in real time.

These dials are anonymous – only the participant knows which relates to them – while the colour-coding allows both instructor and participants to easily keep track of their output.

Being in the white zone, for example, means your heart rate is at less than 60 per cent of maximum – ideal for warm-up and recovery – while the red zone, at the other end of the scale, denotes 90-100 per cent and therefore maximal exertion.

Launched in 2009 and expanding on this offering, the Activio Total Solution comprises a network of receivers located throughout a club or leisure centre. Able to pick up data from up to 200 metres away, this means that anyone working out in the facilities – from the gym and group exercise studios to the tennis courts – can wear a heart rate belt and have their data picked up. Catering for an unlimited number of simultaneous users, the system only recognises Activio belts.

This data is then instantly sent to the individual members' password-protected web pages, via the Activio Feedback Solution.

To allow members to extend this monitoring option to out of club activities, Activio is also launching a range of memory-equipped heart rate watches later this year, to be available for retail through clubs.
