Do any of you guys (and gals) ever get a "rush" from doing compound lifts?
For example; I was doing deadlifts yesterday with the 10x3 scheme. Did a few warm ups at 225 (I'm small, I know), then started into the workout out, with 275. After set 4 or 5, it's almost like a switch flips and I get really focused/excited/pumped/whatever, and my lifts get much better. I finished off the last 5 sets at 300. I'd like to be doing the entire scheme at 315lbs within the month.
So to paraphrase, I feel sort of lazy on the first few sets, then I get a rush and away we go. Same thing with front squats. This never seems to happen when I'm doing say, shoulder presses or curling in the squat rack (hehehe...I kidd, I kidd)...
If this adrenaline or the CNS getting excited or just normal?
