Rock Squats
The term coined by the greatest band on earth, Tenacious D, as an exercise maneuver so exhilerating, it can increase your rock performance and stamina. The exercise is so complicated (has been known to cause minor spinal damage), it has yet to be performed in public by the band nor have the instructions been disclosed.
"Are you willing to make the commitment to deep-knee Rock Squats. Seven or Eight at a time...in a row!" -Jack Black, Tenacious D
