Leg extensions verboten? That's a blatantly wrong statement because you're using it _absolutely_.

You are wrong. It puts undue stress on the knees, even with low loads. I've had 3 knee operations (on one knee!) so I've been through a lot of PT. Open-loop exercises should just be avoided. Their closed-loop counterparts are better/just as good.

Dr. Stefi Cohen had a post about this today, and advocates for them.
