Here is the official Brian J. Noggle scale of a workout’s intensity:
Decent: You mutter to yourself.
Good: You mutter to yourself in a voice from out of The Exorcist.
Very Good: You mutter to yourself in a voice from out of The Exorcist in Latin.
Excellent Workout: You mutter to yourself in a voice from The Exorist in Latin and invoke curses from the dark tome Bellicis Artibus Idoneitatem et Veneficia.
Last night, I had an excellent workout, and I want to apologize to any instructor who is afflicted with painful boils or whose vehicle is destroyed by a hail of toads.
