I know there are loads of threads about this floating round but im a bit confused and want to confirm what fits best with my training regime re Marthon / Ironman Endurance.
What is the formula for calculating HR zones? Is it?
220 – age (34) = 186?
Ive got that bit ok I think but then get confused how to work out my training zones and what they are? Does the training zone % e.g. 65-75% MHR got from the 220 or 186 figure?
Should my zones be:
Recovery 60% MHR or less
Easy 60 – 70% MHR
Steady 70 – 80% MHR
Tempo / Hard 80 – 90% MHR
Could someone post an example at what heartrate zones I should be training, im particularly interested in the endurance building zone i.e. ‘easy’.
