Make sure you eat your morning wheaties...
3 sets Leg Extensions ( real slow and controled for 10-12 then kicked out 6 more fast reps)
14 sets hack squats ( pyramid weight up for 4 sets, then drop back down for 4 more sets and pyramid back up for 4 more sets, then do a heavy 3-4 rep set and for your final do a 20 rep set)
3 sets Leg Extensions 10-12 reps each set really hold the peak contraction
