Looking through my gym i have noticed that the 2 biggest most lean guys only do high rep sets one does them slow and concentrated the other who is a freak burns out or pumps his muscles i bet he did 10 bicep sets in 10 mins. Both of these guys could compete only one guy at my gym who competes does real heavy weight is this a coinsidence? Also there are several strong guys benching 400+ lbs but they dont have the shape as others but you can definetly tell they are strong.
I guess my reason for this rant is how do you know how many sets reps days you need to do? whats the optimum for your body? I could be gettting progress one way but maybe id get more another. I might just be putting too much thought into it but sometimes i wonder how i will ever find the way i grow the best
