Andrew , I guess I'm trying to decide whether to go with Sunnto t6 or powertap.
In your opinion can "stress exersize index" be safely used as "overtraining" indicator and if yes at which levels?
With t6- it is simple if it goes to zone 4.5 or 5 one need to take next 1.5 days "easy" how about your index?
thank you for your answer
