Well I'm just a newbie - so my "advice" may not be a great as some of the old pros around here. But here is what I like to do for legs.
Leg Press
warm up set w/light weights
2 sets per individual leg (12 reps each set)
4 sets for both legs (12 reps each set, keep
increasing weight til I can't reach 12)
Do a few sets for calves too (individual legs)
Hack Squats
2 sets 12/10/8 - when I hit 12/12/12 I boost weight. I "hold" the squat for a second before pushing backup
I'm not doing squats yet cause I'm a bit worried about injuring my back
Lunges (no weights - I put my hands behind my head and do 15 one way,then 15 back until my legs are on fire, I'm breathless and just can't go anymore)
Leg Extensions
3 sets 12/10/8 - when I reach 12/12/12 I up weight
Oh - I forgot to add that I do leg curls - per leg extensions above
Leg Presses, Leg abuduction inner, leg abduction outer
Same as leg extensions
that escalator like thing in the aerobics area - do that with my butt sticking out to get a better workout on bottom/hip area
stretch my legs for 20 minutes
Well that's it. Probably not too scientific, but heck I noticed that my legs are stronger than lots of the guys at the gym
