I'm now doing moderate weight with higher reps. The only reason I'm doing it now is because of a couple injuries. Most of the newer research coming out seems to be pointing towards higher reps for muscle, but I personally think I was getting better gains when I lifted Dorian style.
I usually start out with lighter weight and higher reps. But as I move through my sets I increase the weight and decrease the reps. I feel like this method gives me a little bit of both worlds
