hip bursitis
I assume your question is about exercises for people who suffer from bursitis in the region of the greater trochanter. I also assume that the person has seen a doctor and is receiving appropriate treatment to reduce the inflammation and is cleared to exercise
The best you can do for this client is to do an assessment and see whether some imbalances may have contributed to the client getting bursitis in the first place. You can address those with appropriate exercises. Else, make sure to strengthen the leg and hip muscles to prevent a recurrence of the problem.
