GREAT Post Lisa! what the Curves ladies can't tell is when someone has a higher or lower resting beat than "average" which is what the sign represents. So it's REALLY hard for me to hear them tell me that I'm too high when just standing on the recovery square gets my rate up to 22! LOL I have a heart monitor and so I do get an actual average of what it's been at for the time I've been working out and I've been going WELL over what the chart says since I started my new "intense" workout that another trainer showed me last week. I get red in the face, sweat more, but I tell you what, I FEEL GREAT! I'm going to do this until my next weigh in and see what difference it makes, because if I lose more weight or body fat or inches, i'll continue to do it this way, knowing that my heart will be strengthened too, which is the most important muscle of all ;)

Thanks for all the references. I've done a little research myself, but it's always nice to find more backup!

Have a wonderful workout!
