Does anyone remember the old Callanetics videos that claimed you'd look 10 years younger in 10 hours? I don't know about all that, but I did buy one when I was a freshman in college, and it did help me tone up a lot! It's kind of like pilates type moves, but many of them include pulsing or bouncing.
Anyway, I just read that the founder died about two months ago, but I wonder if anyone still does those workouts? They have updated versions, but I'm afraid those won't be the same as the old school things.
