Ok, I do deep knee bends as an exercise, but I call them "Sinus Rhythm" because it sounds cooler, plus it's based more or less on this...

(Sinus rhythm starts at 0:41)

But, instead of the music they use, I found one that works much better for me. However, it is probably not the best choice as far as title...

But, it motivates me to AVOID one!

Have yourself a great day!
