Are you allowing yourself enough recovery time? It is as important as the training.
That's sort of what I thought - not necessarily over-training, but that a rest day is needed.
What's this 20%, guys? How to stay in the wimp zone? When your tongue hits your knees, you're almost there - wait for your vision to start graying around the periphery. Then you've found your max HR. Isn't 80% of max considered the 'dead zone?' where it doesn't let you gain strength, recover, or condition your cardio system?
