Hi Cat/Bethany...Thanks for switching me onto the Myzone MZ-3. I used to own a Wahoo HRM until it broke only a couple of months after I bought it and my workouts have suffered since. But now i'm back on track and my "inner geek" is loving this new bit of kit. And now, because I can monitor my effort during my workouts, I feel it's time to bring on the SWEAT :-). I;ve just registered with you guys and downloaded my first 3 classes (trying my 1st one tomorrow YAY...I think :-). I hope to sign up for my A.A.P. soon, as soon as I sort some streaming issues out. But in the meantime, I think the classes I have will be more than enough to keep me occupied, Thanks again.
