Legs Workout!!

Alrighty, Today's workout wasn't half bad.  Different and delicious.  But I can guarantee tomorrow, legs will be mega sore.
You will be using machines for part of this routine.
Three triple sets.
Do each set 3 times, without resting.  Boom Boom Boom
Then take a 1 minute break, and blast out the second set three times.  Take another minute break, and finish hard with the ab portion.  You don't need to use heavy weights in the first two sets, you will get tired too fast, and you want to be able to complete your third set at fatigue.  It should be easy-ish the first time, difficult the second, and the third, you should barely be able to finish.  Oh and you  might want a towel...You're going to get sweaty.  Hehehheh. Cheers!!

Do a quick 5 minute warmup.  Sprinting, elliptical, jumprope, whatever.
