Leg extensions. Worth it or worthless

AFAICT, Rob Shaul seems to have popularized the idea (at least with the general public) that eccentric loading is key and came up with leg blasters to address the issue...though none of the exercises in leg blasters actually have a purely eccentric component.
Personally, I don't think it's so much the eccentrics as I think it's the idea of resisting downward acceleration. Of course, resisting downward accelerations is a primarily eccentric load on the legs, but it's different than a slow eccentric load. That's why I like banded barbell back squats, where the bands accelerate you downwards faster than gravity, and the drop snatch, where again you have to accelerate downwards faster than gravity by pushing yourself under the bar. I also love jumping lunges, which as DTM said, is probably the best part of the leg blaster complex.
This thread has gone full on EpicSki, PugSki, or CrossFit bro. Not sure which.

Leg extensions. Worth it or worthless
I’ll disagree with many posters here. While squats and lunges may be more effective, extensions isolate and work the quad. Anyone with patellar tracking issues will use this important exercise and realize its benefits.

Leg extensions. Worth it or worthless
Struggled for 2 years with PFS and the docs at Boise State put me on a program to strengthen the VMO, hips, ass, and it was a lifesaver.
Some people have bad issues with cartilage degeneration behind the knee, and I’d wager that extensions aggravate that particular complaint.
Extensions worked really well for me. Full rehab took 4-5 months.
