-Currently in PR shape (just under 15:00) 5K
-resting HR around 45
-HR between intervals 4and5 during 6x1K (60sec rest) in 2.58 was 80.
-HR on 12x45sec hill sprint session at maximum work level was 159.
-never taken HR measurments before
Is there anything to this? Does it mean anything significant.. ie im not maximising potential or could it just be a low max HR?
insight welcome... thanks.

So how can you say your HR is "low"?!?
isnt 140-160 meant to be aerobic running? Clearly I dont know all the details!
That's why im asking... if you have an answer, please enlighten me oh great one...
Lying on your couch is aerobic.
Two things, maybe your maximal heart rate is 165 - 171.
Another possibility is overtraining. At a certain point your "heart can't keep up anymore". If you feel tired a lot i would think the lather.
Then there is one more possibility that is that you have an unusual thick heart wall. That does not always have to correlate with low maximal heart rates.
training heart rates are even more individual then training paces. Everyone will have different maximal heart rates and even that might differ over time with you. If you work out a lot your maximal heart rate tends to decrease by 10 bpm (because it has grown and big engines don't need to rotate as fast) It also decreases a bit every couple of years just by aging.
Some people have maximal heart rates of 140 by the time they are 60. So would they still training aerobically at that heart rate?

Yes they would. VO2max is maximum aerobic capacity.
Each exercise would still be aerobic but not in the letsrun sense besides vo2max is lower at maximal heart rate then slightly below maximal heart rate.
If you're looking for someone to say 'Wow, you're HR is really low you can run much faster...' forget it. 45 is nothing special for a runner.
Runners have had resting HR's as low as 32. Try to get below that. Best to keep it above 0, however.
Are you underweight? bradycardia (low heart weight) is a symptom of anorexia. I'm not saying you have an eating disorder, but maybe you should gain some weight if you are borderline.
