The End of Stiffness with This New Type of Stretching

The right kinds of exercise can improve health and fitness without hurting joints. Combined with a treatment program, exercise can add to quality of life. And it can:
Strengthen muscles around joints.
Help maintain bone strength.
Increase energy.
Make it easier to sleep well.
Help control weight.
Improve balance.
Improve mood.

Bones need strong muscles for support. Not exercising weakens those supporting muscles. Weak muscles put more stress on joints.Exercises for arthritis might include exercises that put joints through their full range of motion and strengthening exercises. Exercise that raises heart rate, known as aerobic exercise, is also important.These exercises help build strong muscles that can support and protect the joints. Weight training is an example of exercise that can help build and keep muscle strength. Using resistance bands, hand weights or machines can help build strength.
Weight training should be done every other day for at least two days a week. It should include all the major muscles in the body.
