Input:
The workout is very good.  It is very challenging and I always feel like I got a great workout when I'm done.  The problem is Mr. Kest.  I have to turn the volume all the way down because he is so very annoying!  His vocal tone, poor use of the English language, and accent really grate on me.  It actually keeps me from wanting to do the workout!!
