physical pain while listening to AM6 - normal?

[achtung81]

Hello all,

I am currently on my second run-through of Alpha Male V6, and the program is kicking my ass. Stage 2 has been absolutely brutal, and it seems that this second run-through is just as bad - if not worse- than the first.

I've been experiencing physical pain - in my back, arms, neck, and sometimes hands. Has anyone else also experienced this? I'm a bit freaked out...
