ok im goin off line now so ill answer that one for you!
your legs have 2-3 times more muscle than your chest so if you train around 20 sets for your chest you must do 40-50 sets for your legs!!does that sound right,no it doesnt.
you are doing way way way too much which tells me
1.you dont know how to train properly
2.you are going very light
3.you are taking the piss.
keep listening to your mate you cant go wrong
i didnt wanna come across like that but looking at your recent responses you have no clue at all mate.
