With regular exercise, people who have arthritis experience less pain, more energy, improved sleep, and better day-to-day function, according to the American College of Rheumatology (ACR). Without it, they are likely to have less tolerance for pain, weak muscles, stiff joints and poor balance.

ACR's advice is to do one or more of the four major types of exercise – flexibility, which help joints and surrounding muscles in range of motion and stretching movement; strengthening, which improves muscle strength and reduces bone loss; body awareness, such as yoga and Tai Chi, to improve balance and coordination; and aerobics, to improve heart, lung and muscle function.

Before starting an exercise plan, individuals should consult with their doctor. "For people with arthritis, exercising is an important part of a treatment plan," said ACR president Dr. Stanley B. Cohen. "You don’t need to train for a triathlon to experience the benefits of exercise. Starting slowly, with low intensity, will allow you to ease into a successful exercise plan that will benefit your arthritis and your overall health."

Exercise and aquatic classes for people with arthritis are sponsored by facilities within the North Shore-LIJ Health System in cooperation with the Long Island Chapter of the Arthritis Foundation.
