Seated leg extensions are a sound recommendation. I have a Nautilus seated leg extension / leg curl machine at home and my ortho indicated that slow continuous motion, minimizing any stopping/ hold was key to maintaining knee health. I am suprised with the decades of abuse my knees have survived.I was under the impression that leg extension can be strenuous for the knees.
Oops probably no more than climbing down mountains.
My shoulders are different story.
