DJing hurts my neck and back!

 Well, I set up the Native Instruments S2 last night, and my neck and back hurt after 5 minutes! lol.  Apparently I may have to raise where the controller sits to alleviate my symptoms.  Much respect to DJs who can stand up like that for a 4 hour set or more.  I think I will spin my beats and instrumentals because I know my own arrangements so well.  I want to get into other genres, but it will take time.
