And I am pretty confident when I say that nobody but Richard Simmons would have an exercise move called "Sizzle". ( To "Sizzle", all that is required is shaking your hands in a flashy way as you bring them from over your head down past your shoulders to your waist- as you march in place, of course.)
All in all, it is an entertaining way to get an hours worth of exercising in. And flashing back to all the aerobics classes I took in my 20's is not a bad thing. I just hope nobody is peeking in the windows as I sizzle.
