Most Uber Leg werk out

Ok im no stranger to leg day but yesterday i expierenced what one might call.. a "PainFull Orgasm"? this is how it went
Ride Bike till HR is 130 for 2min
2x20 leg ext Light
1x Leg Curls Light
SQUATS
did 4xSets of 6-8 w/ mod/hevy weight
no not just any squats though... EVIL SQUATS
i started out w/ mod/light weight doing slow squats onto a bench but it seemed to high, so i found a Stability ball w/ a lil less than 12in Diameter. i surrounded it 5lb plates to keep it from rolling away and then i would squat down on to that lil beast and u know you wouldnt think it would make much diff but i have never had quad pains like this before. I HURT! i kant walk! i am in heaven :)
Lunges SLOW 5xSets
DB SL Deads 3x Hevy
and calld it a day...

Yesterday I did
Angled standing calfs 1x15@300, 1x12@320, 1x10@340, 1x15@280, 1x15@280
4x12 at 315 regular parallel squats
Then I did machine lunges. 1x10@155(unloaded bar weighs 15lbs) (1x4@155&1x4@105) I know drop set right there was bad, but it was failure, had to use my quads to get back up when you know it's supposed to be a glute exercise. 1x10@15, 1x10@115
Then Lying leg curls 1x10@120, 1x12@100, 1x10@100, 1x12@90
Adductors 2x8@130
Crunches 5x25
I was really low on glucose or how ever you spell it. Felt all discombobulated leaving the gym. I love days like that.

dam dood is that like a 2hr work out?

I squat all the way to the floor, Keeps my legs sore for days. The regular 90 degree just wasnt cutting it anymore.

Some say its not necessary to go any lower than parrallel...personal preference i guess :unsure:

Going below = kan rape the connective tissue backing your petella and like... but man its awsome for swelling up the quads

Did y'all read that thing in the lifting techniques about squating big?
Here.
It's a back/glute thing. 1" bellow parallel is all you need. I occasionally to box squats set up 1" bellow parallel to get my body used to squating like that. Then when you go heavy, it's second nature to go that low with out the box.
If I want a thigh pump, I'll do super sets of leg extensions and leg curls.
