Thank YOU for the feedback. I can use the info myself to improve my training. I am still sorting out this training thing and have had concerns with accurate training zones. When I first started training, I was not working hard enough to make a difference. I was afraid to overtrain and began reading some material. This gives me a bit more to chew on. I am new to the forum and hope to learn a lot from the posts. Anything you feel might be helpful will be greatly appreciated.
