Is there any exersises for people with arthritis?

Yes. Any exercise you want you as far it dose not heart you, the best water exercises. Good luck.
Absolutely. Exercise is generally a very good idea for people with osteoarthritis which is the most common form. In rheumatoid arthritis which is not as common, exercise needs to be more carefully considered particularly if one has an acutely inflamed joint. There are so many types of exercise, it is best to be evaluated by a specialist in this area. This is typically a physiatrist or a rheumatologist.
