Chazz E. Quad Sweep Superset

SpirituallyBuff Coach Jaron Singley works team athlete Chazz Evans through this torture combo.
On this day, we had Chazz pre-exhaust with a few sets of moderately heavy squats (working our way to 275lbs x 4)
Then we did a VMO superset, using these same two machines.
Assume a wide stance and turn your toes out in a frog-style stance. Allow your knees to come down outside of your body, so you'll be sort of pushing your knees out as you lower the platform. This version of the leg press is more for quad sweep (vastus lateralis).
The concentric portion of the lift should be done explosively.
Keep going up in weight until you get 20 reps and be sure to push yourself. If you reach 15 reps and need to rest a second before going for 20, that's okay.
Do 20 reps on all sets. Do not lock these out.
Now superset these with partial leg extensions using the top half of the movement. Flex hard at the top and only lower the weight half way before driving back up.
