The first of the Polar range to have tracking abilities as well as a wrist-based heart rate monitor, the A360 is a game changer for Polar. You get access to personalised training guidance through the use of ‘Smart Coaching’ which tracks fitness levels, plans goals and encourages you to maintain the correct intensity. It even buzzes with an inactivity alert if you’re having trouble putting down the beer and picking up the barbells. You can also receive notifications of calls, messages, and social media updates.
