The following are done in ONE set without rest in between exercises (consider is a superset):
First set; single leg quad extensions (with only your right/left leg and then alternate to opposite leg)[6+ reps/leg], single leg hamstring extensions (right/left leg first and then switch)[6+ reps/leg], followed up immediately by the incline leg press [as usual, use both legs with normal form going until legs are around 90 degrees or so with a slight pause at the bottom and controlled push back up [8+ reps], immediately followed up by placing your toes on the botom corners of the platform they're usually on and raise the weight only 1-2 inches above the pegs it was resting on [15-20 quick reps] ]
Congrats on completing your FIRST set! Continue to raise the weight and repeat for sets 2,3, and 4. Drop the weight on the last set and go until failure with everything.
The key to this INTENSE training is using one leg at a time. When using both legs, one tends to compensate for the other. On the incline, try to use both legs together without one leg being more dominant.
