The Sicilian Crunch put me on the map many moons ago. Consider this as the reverse action. It’s a negative-accentuated glute-ham raise emphasizing the knee flexion component.
If you have access to this machine in your gym, give it a shot. Do 4 sets of 2-4 reps with an 8-second lowering.
Expect your hamstrings to be sore for a few days!
