Heart rate zones - Struggling to stay in a low zone!
I recently bought a heart rate monitor to complement by Edge 800. I have found that whilst our on my rides, I struggle to stay in a low heart rate zone. Now, I'm a bit overweight still (79 kg aiming for around 65-70 kg) and a bit unfit too, cycling regularly is my first proper exercise for a long time!
I find that my heart rate is always around the 149-186 mark for the majority of the ride, around 80% or so.
Is this something I should be overly concerned with? This link http://www.bikeradar.com/us/gear/article/heart-rate-monitor-training-for... suggests for endurance and weight loss to usually be in zone 1-2, perhaps 3 (so for me between 115-157 bpm).
I find I get bored if I go slower, but will going slower really drop me into those zones? I don't go extremely fast (again, because I'm unfit). Should I just keep doing what I'm doing? Or look to go easier?
Sorry if this isn't the correct place to ask. Hope someone has some advice Thanks
