Okay, I will share the secret to freaky legs with you.
You should always start with these. Work down from 3 sets of 15 to 5 sets of 4-5 over 5-6 workouts - periodize.
These are so under-utilized. It’s seriously gained secret weapon status. This is the only exercise that gets my glutes sore any more. Do walking lunges with a barbell or dumbells - no sissy-ass split-squats.
I used to ‘close’ with leg presses, but saw too many bitc…bodybuil…I mean guys doing them like little fruitcakes. Plus, you have to load a crapload of weight to get any effect. Front squats will finish your front quads.
Rest. I split leg day into two parts - front-leg and rear-leg (more or less - lunges are a grey area).
A few hours later, do your SLDL until you feel like puking. Then do leg curls, and finish off with calf work.
Seriously - your legs will grow… Quickly.
