The standing or side lying quad stretch is too hard for my student who has limited knee flexion. What other stretches would you recommend?

A half kneeling position (also known as 1/2 monkey in yoga), where one leg is kneeling on a padded surface and the other foot is on the floor at a 90 degree angle. Tucking the toe of the kneeling leg and shifting the hips forward will increase the quad stretch.

Thank you! This is helpful!

I have a clients with knee what are the most recomended exercises and what are not recomended at all.
