Maximum Intensity:"It is inevitable that this argument will never be resolved, because individuals respond to different stimuli and workloads. You can argue until your blue in the face that what you do is the best, but the fact of the matter is what works for you will not necessarily work for me. "
I would have to disagree with you on both of your arguments. If you mean stimuli to mean that different people need to use different poundages then you are correct. However everybody requires the same workload to stimulate growth. Here's the logic: Is the hardest rep of a set the first rep?the 5th?No it is the last rep, because it is that rep that requires more bodily resources to complete it. The last rep that takes you to + failure is requiring maximal intensity and contraction. If you could curl 120lbs for 10 reps but only did 4 do you think you would ever grow? No. If you did 8 reps would you grow? No, you must carry a set to positive failure if you are to stimulate an increase in strength and size.
Your second argument is what works for me may not work for you. That is also physiologically incorrect. Using the biecp as an example: Your bicep works the same way as mine. The sole purpose of the bicep is to contract. This is universal in all humans. Likewise, our bicep is composed of the same material, there is no human that is born with a bicep made out of fat, magnesium, or anything else wierd. Since we are similar in physiological structure, we also share the same stimulus needed to produce growth and size (training to + failure).
