No I'm not autistic (not very at least) I just thought this was a pretty cool idea. I'm not obsessed with the movie or the book, (I mean I've only watched the movie 20 times and read the book 5 times, but still). I just tried this workout myself and my entire body feels like it's on fire. I doubt this is going to do very much when it comes to building muscle mass but it WILL build mental strength. A word of warning though, Bret Easton Ellis is an author and I'm pretty sure that he knows as much about lifting as my grandfather does about computers. This way of training WILL hurt you if you're a newbie or if you have shit form:

Stairmaster 20 minutes

Leg machines 5×10

Back machine 5×10

Weighted crunch 6×15

Bicep curl 7×10

20 minutes exercise bike

Leg extension 3×15

Leg curl 3×15

Leg press 3×15

Barbell curls 3×20

Rear delt flyes 3×20

Lat pulldowns 3×20

Cable rows 3×20

Deadlifts 3×20

Bent over barbell rows 3×20

Incline bench 3×20

Lateral raise 3×20

Dumbbell press 3×20

Close grip bench 3×20

Cable pushdowns 3×20

And some stretching to prevent Imaginary Lats Syndrome.
