I really push myself when I train. Sometimes I'll have days where I can only do a few sets, and other days I'm so ****ing psyched that I can bust out 5 more just because I have the determination to go on. Plus I like to lift heavy.
So I try to get in a lot of volume on my full-body routine. As much as I can each day; with reps mostly in the 1-5 range to get in the heaviest weights I can. I aim for 30 total reps per exercise on a good day.
Form follows function.
