I found this fantastic youtube channel AskDoctorJo

She is a licensed Physical Therapist and Doctor of Physical Therapy.

The videos feature stretches and exercises for common injuries and syndromes.
Lots of excellent exercises especially as you age

Check out the channel. https://www.youtube.com/user/AskDoctorJo?spfreload=5
