Although I have long understood the importance of avoiding aerobic exercise with CFS, this article provides some very specific tips about how to figure out where your limits lie, how to monitor heart rate, and how to use this information to stay within your limits (which will, hopefully, help you to eventually increase those limits). It's filled with excellent, specific advice. I certainly plan to put some of this into action immediately!
Hmmm...I wonder where my old heart rate monitor is? Of course, the last time I used it, I was trying to increase my heart rate! I'm definitely going to dig it out of my old exercise stuff.
