train with high reps I get delayed onset muscle soreness in the low reps not as much at all. I mean thats some proved hard facts right there, that 20+ reps per is the sweet spot. Triceps, chest, traps and legs always get sore, why, because I always use high reps with those muscle groups. Finally I make some real scientific breakthrough with my training and keeping all these notes payed off, I know it would come down to experience.
So what does that mean, we only do 20+ reps for everything. Fact.
