Still waiting for your explanation for why you used the example of the sprinter to prove that low volume works with heavy weights work for mass since bodybuilders have more mass than sprinters and sprinters do a lot of volume with their sprinters.. Oh brother, that was dumb even for you. 
Anyways, 6 sets for arms is 21 days is not strengh training. I have Mike Mentzer's Heavy Duty, and he doesen't even advocate training arms. His routine is nothing but deadlifts, military presses and dps. Do you really think powerlifters do barbell curls and triceps kickbacks, genius? Again, six sets for arms with reps in the 6+ range is hypertrophy training and not strengh training. You: stupido.

You change your arguments every time you rebut someone's argument. You have to do this because you get owned by everyone on here. You specifically stated that that 6 sets for arms over 3 weeks is NOT LOW VOLUME (these are the words you used). Yes that is low volume. High volume trainers would hit 6 sets of arms in each workout.
If your panties are still in a wad over my sprinter example then I am not sure what to tell you. I already explained it so a 5-year old would understand, but you still seem to be grasping.
Let me try one more time: sprinters have fast-twitch muscle fibers (remember the explosive ones); they maximize these by performing olympic lifts and also low rep squats, deadlifts, and push press. Their weight training program is typically 2 or 3 times per week which is low volume. In accordance with this type of weight training they build muscular size as well as strength and power.
I never claimed sprinters have the size of bodybuilders. This was another one of your desperate twists, kind of like when you started counting every step a sprinter takes as part of their lifting program.
