ACTUALLY, THROUGH EDUCATION AND RESEARCH, THE MAJORITY OF THE MUSCLE FIBERS IN ALL HUMANS IS ONE THAT RESPONDS BETTER TO HIGHER REPS, BEING THAT OUR LEGS CARRY US EVERYWHERE WE GO, STAIRS, ETC. THEY CAN HANDLE A LOT OF WEIGHT, AND CAN DO SO FOR A LONG PERIOD OF TIME, HENCE THE HIGHER REPS. SO, I AM NOT ASSUMING, JUST SHARING ACTUAL FACTS ABOUT MUSCLE FIBER TYPES AND WHERE THEY ARE LOCATED. THEN AGAIN, JUST DO WHAT WORKS FOR YOU, THAT IS WHAT I'VE DONE ALL MY LIFE, AND WELL, I'D SAY I'M PRETTY SUCCESSFUL WITH IT AND THOSE I HELP AS WELL.
if a persons legs have substantially (and i mean substantially) more slow-twitch fibers in them, then yes, a lighter weight with more reps as you suggested will give them better growth. however, if they have a decent amount of fast-twitch fibers in their legs, as many people do, heavier weights with more reps will be far more effective.
SEE ABOVE ONCE MORE.
the optimal way to see what works for your legs is to go heavy with low reps first, and if you fail to see growth from that, then and only then lower the weights and up the reps and see if you get better results.
I DON'T SEE THAT AS OPTIMAL AT ALL, BUT YOUR ENTITLED TO YOUR OPINION AS EVERYONE IS.
