Can a person with Rheumatoid arthritis perform Kettlebell workouts?

Honestly, if I were the person with RA, I would ask you what do you know about rheumatoid arthritis?

FYI, RA is a systemic disease. Inflammatory rheumatic disease can affect cardiac and pulmonary function as well as cause widespread vasculitis. If you unfamiliar with the exercise effect as a consequence of the disease in addition to how the medications that are prescribed to treat RA effect the exercise response, it might be best to refer.
