For every pound you gain, your knee feels four pounds' worth of stress and strain. Lose a pound, and you reverse the effects. The Arthritis Foundation recommends these exercises. Do these every day. Strengthening exercises to maintain or increase muscle strength.
Strong muscles help support and protect joints affected by arthritis.
Do these at least every other day. Endurance exercises to improve cardiovascular fitness, help control weight, and improve overall well-being. Do these for 20 to 30 minutes three times a week. Swimming or water aerobics in a heated pool gives you the benefits of exercise, and working out in water takes the pressure off sore joints. You don't have to go to a gym or work up a sweat to get exercise that's good for your joints.
