First of all, I never did get my heart rate up into the working zone, even during the fastest songs. But one thing that did happen, before I even got up to "Great Balls of Fire" and The Twist, was a pain in my left knee, in the back, behind the knee joint. Just lifting my leg would cause it to twinge. At that point I knew I wasn't even going to attempt to Twist and just modified the movements.
Tomorrow it's back to Leslie. I may not do my treadmill time today to give my knee a rest.
I've never injured myself doing any of the Walk at Home videos, but over the decades I have injured myself doing Richard's videos. I dislocated my shoulder while doing a toning video about 15 years ago; more than once I injured one or both knees; my lower back got twisted a few times. I guess it's time to put these videos aside and go back to doing what I've been doing with them - using them just for the music while using my exercise bike.

Go to the Kelly Olexa blog and read this post. She sums up exactly what I've been whining to my husband and doctors about for a while now. I see I'm not the only one frustrated with all the conflicting information out there.
