The F55 is the top of the Fitness Range from Polar. It is the upgrade to the Polar F11. The upgraded features include Polar Ownrelax, Polar Bodyworkout for gym work and Infra red data transfer to your PC.

Polar Ownrelax is a fantastic feature that will let you know how mentally relaxed your body is. Have you ever had a training session that for some reason doesn't go very well? You don't feel as strong or as energetic and you can't put your finger on why this would be? Well a lot of this has got to do with your mental state - if you have got a lot on your mind, your heart rate variability will not be very consistant, and therefor you will not be able to perform as well in the gym as you normally do. This test is all about finding out how mentally able you are to face a training session.

Polar Bodyworkout is great for people who want to know which exact exercises are best for achieving the required results. It will tell you which exercise to perform, how many sets and how many repetitions to perform to achieve your goals e.g bigger arms, solid abs etc.

The IrDA Data Transfer to your PC is a lot quicker than the sonic link that is available on the cheaper models. The F55 has a built in IrDA transmitter (as well as sonic link if necessary). If you have infrared inbuilt in your PC, or you have an IrDA USB receiver then the watch will be able to transfer data super quick.
