The present invention relates to an exercise apparatus for joints and pain treatment, which enlarges the contact area between an exercise apparatus body and the human body by a flat part of a fixed width formed on the upper and lower sides of the exercise apparatus body； and allows exercise apparatus bodies formed in two to be integrally mounted by a connecting part, thereby allowing a muscle in a contact region of one exercise apparatus body to be contracted or allowing a muscle in a noncontact region of the other exercise apparatus body to have a different center and be expanded so a stretching effect by muscle can be obtained. Particularly, the exercise apparatus can has various stretching effects on a joint region where pain is agonizing. Furthermore, the surfaces of the exercise apparatus bodies and the connecting part between the exercise apparatus bodies are covered with a covering part of a fixed thickness made of Ruton that has a great frictional force and is soft, thereby preventing damage to the skin of the human body touching the covering part； and allowing the exercise apparatus bodies to always touch the skin in a soft state and also promote the circulation of the blood and lymph of the human body due to a great frictional force. In addition, the exercise apparatus relieves a regional ischemia of the human body via the exercise apparatus bodies formed in two, thereby allowing the circulation of the blood to be promoted. The main points of the technical constitution of the present invention are as follows. A flat part (110) of a fixed width is formed on the upper and lower sides of an exercise apparatus body (100) made of rubber in order to enlarge the contact area between the exercise apparatus body (100) and the human body. An adhesive (130) is applied to the end of the contact part between exercise apparatus bodies (100) formed in two, thereby allowing a connecting part (140) to be integrally mounted. The surfaces of the exercise apparatus bodies (10
