Does anyone use a heart rate monitor?
Last time I went surfing I had an action cam strapped to my neck, and looking at the footage afterwards I can clearly hear my pulse pounding away, and from that I worked out that paddling out, my heart rate was between 150 and 160 beats a minute.
There are lots of different ways to work out maximun heart rate, but that rate of 160 bpm worked out to be around 80% of my maximun heart rate, it is important as at that rate you are only burning calories from about 15% fat or something, I only mention it as if you want to lose weight and burn off fat, you should be doing exercise at around 60-70% of maximun heart rate, in that zone the body burns calories from 85% fat.
I'm no expert but thought I'd mention it anyways.
