Anything under about 5 minutes, I'd typically just ignore your heart rate and go as hard as you can, but only as hard as you can for each and every interval.ibexbiker said:I use heart rate to train because I don't have a power meter. If an interval is 2 minutes long and it takes me 40 seconds to a minute to get my heart rate up to the level it needs to be am I cheating myself? I know the heart rate lags behind effort and it will still stay higher for a little bit after stopping the interval. But if the program says a 2 minute effort at 88-90% of max for example, and I am only at that level for 1-1 1/2 minutes I am sort of cheating aren't I? Should I not start counting the two minutes until my heart rate gets to the desired percentage? Even if I am busting butt to get there?
I know this is a beginner question but I am starting to actually train a bit for races as opposed to just riding and entering the occassional race.
Little harder to do using Perceived exertion, but more important so when using a heart rate monitor that you do intervals properly. Aka, don't 'sprint' at the start to push your heart rate up then fade off. This article can help answer some questions
