Brutal Leg Training

Ok, this workout was pretty brutal. I used 10 seconds between sets of all exercises and the only warmups I did were for leg extensions and leg curls. Here it is:

Leg Extensions 250x17, 225x11 all reps with 3 sec. static hold
No rest right to Loaded squat bar:
Squats 315x15, 285x15
No rest right to loaded Hack Squat machine:
Hack Squat 270x15, 235x15(barely)
2 minute rest to warm up then:
Hammer Strength Seated Leg Curl 115x13+2, 105x11+2
No rest right to loaded bar:
Stiff leg deadlift 225x2x15 10 secs. between sets
Seated calf raise 100x2x30 each rep held at top and bottom for 5 secs

Finished off with 5 sets of abs and was out. Squats were done ATG style wearing a valeo belt.
