I'm just doing it on feel at the moment and going the hardest I can for the specified duration.
HR is so slow to respond though - maybe it's ok once you get there but, if you try to hold it, you'll have to back off the power to stop it climbing higher.
I'm just doing it on feel at the moment and going the hardest I can for the specified duration. Even when going at the same pace for an hour, my HR continues to increase during the recovery period afterwards so my experience of using HR as an indicator of how hard i'm going just seems bizzarre...
I don't get it. Please enlighten me. How do you use it during intervals? Perhaps there is an effective way of doing it but, as i've only ever used a HR device once or twice, I have no idea how it would work properly. Am I missing out on something by not having any HR gadgets?

I try to do 2 X 20 min sessions but have never managed it. I try to keep a steady modest 180 watt (not sure of the accuracy) but after 10 mins my BPM has increased from 80% to 95% of MHR and I have to ease off is this just an indication of unfitness?
