I think I want a HRM but not sure what they entail!
I like the look if the Polar watches but I keep looking at them and it lOoks like there is a chest strap with it? Do you need both parts for it to work? Is the chest strap restrictive?
Id ideally like one that's just a watch that measures my wrist pulse, is this an actual thing or shall I just give up? I'd like it to do calories calculation too. Do I even have any idea of what I'm talking about?
Thanks!
