Comming from a psychological background I am just wondering what type of mental state do most of you train with. When I was younger I blasted the "angry tunes" like Mettalica, Danzig, Iron Maiden, DMX, etc. to get me pumped and focused on angry energy to blast through weights and sticking points. My old quote was "I PUNISH MYSELF TODAY TO PUNISH OTHERS TOMMOROW" which created an angry get thr F out of my way attitude when training (without being a dick about it in the gym). Lately countless articles have highlighted that this so-called negative energy is wasted and drains physical limitations. Supposedly you should focus on positive energy and mental rehearsal of lifts before doing them, such as "I can do this wieght and envision yourself doing it before you attempt it" blah blah blah, as taught in sport pyschology priniciples. I still believe to this day that when I blast the "pump up" tunes and get a little aggressive and angry I fight harder on my lifts. Just wondering if anyone has thought about that aspect and how do you set yourself up mentally before and during workouts....Please comment
