Rest is an important thing, but if I have added time for training and feel as though I am recovering well is it a good idea to increase the time training as long as I stick with 80\20, or is it better to abstain from further training to avoid overtraining?
I have always followed my own plans but really want to maximize the 80\20 training philosophy. That being said, if I am on a planned 1hr30min zone 2 bike ride and have the time to continue for another 30 min is it better to stop and stick with the plan or can I continue on and add on some additional training?
