One thing is very obvious, Brian trains like a noob kid.
Obsessed w/ mirror muscles. Admits he's too lazy to load up plates in the gym (SQ/DL etc).
The brutal work = heavy back & legs (and no, not "leg extensions").
Millions of poses enjoying his own reflection.
When he turns around, he disappears. No hams, no back, zero thickness nor width, etc... The hard work is skipped...
Pump & pose...
