NOVELTY - The strengthening and rehabilitation exercise apparatus has a stretching apparatus which solves back and shoulder muscle strain and pain through muscle exercise of the back and the shoulders using hands and arms in sitting position. A waist joint strengthening and rehabilitation exercise apparatus strengthens the waist and the abdominal region through exercise of the upper body interlocking with the weight while fixing legs and the pelvis in a straight line in supine position.    USE - Strengthening and rehabilitation exercise apparatus for training pelvis, waist, back, and shoulders of human body in standing position, supine position, or prone position to prevent and cure regressive diseases e.g. lumbago, urinary incontinence, and osteoporosis.    ADVANTAGE - Enables to effectively train a human body including a pelvis, a waist, an abdominal region, a back, and shoulders while reducing the number of exercise repetitions and exercise burden. Enables easy training of an upright core to effectively deal with regressive diseases while discovering fundamental causes of the regressive diseases and reasons why such fundamental causes are not overcome. Enables training an upright core including legs, a pelvis, a waist, and an abdominal region of a human body using a direct exercise therapy and stretching a back and shoulders of the human body, thus, solves problem related to regression of the human body. Enables to perform hip joint exercise in a prone position such that the hip joint exercise is not affected by gravity. Provides a waist joint strengthening and rehabilitation exercise apparatus which improves abdominal obesity and waist pain through exercise to bend or straighten the upper body of a user about the waist joint of the user while fixing legs or simultaneously fixing the legs and the pelvis of the user in a sitting or standing position.    DETAILED DESCRIPTION - The strengthening and rehabilitation exercise apparatus has a stretching apparatus which solves back and shoulder muscle strain and pain through muscle exercise of the back and the shoulders using hands and arms in sitting position. A waist joint strengthening and rehabilitation exercise apparatus strengthens the waist and the abdominal region through exercise of the upper body interlocking with the weight while fixing legs and the pelvis in a straight line in supine position. A hip joint strengthening and rehabilitation exercise apparatus strengthens the pelvis, the abdominal region, and the waist through exercise of upper body or lower body with the weight while fixing the lower body or upper body in sitting or prone positions respectively. The hip joint strengthening and rehabilitation exercise apparatus has a structure in which a footstool is mounted at one side of a stationary frame (1) with sliding board. An exercise frame (2) is slidably mounted at a sliding board. An exercise resistance controller (6) that interlocks with the exercise frame is mounted at the stationary frame. The exercise frame includes an upper frame (3) and a lower frame (4).
