Suunto's new M4 sports watch acts as a heart rate monitor and a personal trainer, giving you the ability to set fitness targets by entering simple information about yourself.
It starts off by conducting a basic fitness test that involves a brisk 1km walk, and it configures the data from this exercise to create a customised fitness plan for the user.
We found the heart rate strap (included in the box) to be a comfortable fit and were impressed with the simplicity of the watch’s setup and functionality. But it doesn’t have room for a huge amount of data.
It’s a good value option for beginners and intermediates, but if you’re a more advanced athlete it may pay to look elsewhere.
