what would you guys said about this schedule? its what top sprinters in argentina are doing right know, crazy volume!!! 
warm up
leg extensions 4x8
leg curls 4x8
front squat 2x6/2x4/2x2
back squat 2x6/2x4/2x2
1/4 squat 6x6
three days a week + upper body + conditioning...
you must be on roids to finish this and make gains
Hm, I think the volume might be pretty high depending on whether all those are actual work sets. If the weight gets ramped up from 2x6 to 2x2 in big jumps then that would change the perspective a little. I wonder about the exercise selection though. Not a fan of the leg extensions. Would also do leg curls at the end. Don't know why they front squat in the same session with back squats. Why do they front squat at all?
I think it is looking weird, but sure you can get stronger with that, even without roids. The most resource efficient approach? Don't think so.
i've done something similar with front squatting before back squatting, felt great.. work up & hit a few work sets on front squat, then transition right into back squat.
as for leg ext/leg curl pre-squatting, it could possibly help facilitate an even better warmup, get those muscles firing better pre-squatting.. normally people put isolation stuff after the big compounds, like myself, but, it does make some sense to get in a little volume pre-squatting, could possibly be beneficial.
when i see the squat volume there, i initially think no-grinders on those sets, so, that makes the routine a bit more bearable.. if any of those reps are strainers on the 2x2's for 4 total sets, that session would kill you pretty bad, for a few days.
