ABSTRACT:
A physical fitness training apparatus which may be readily installed in a door frame. The apparatus includes an extendable screw threaded support bar assembly (22) having rubber feet (28) at either end which may engage the sides of a door frame in an elevated position. Mounted on the support bar assembly are two radially outwardly extending eyes (52). A first pulley block (14) may be secured to one of the eyes (52) by a quick connector (60). A second pulley block (16) is provided and intermediate portions (74, 76) of a primary line (18) engage the sheaves (58) of each of the pulley blocks. The ends of the line are formed into eyes and one end (80) may be connected to the other radially outwardly extending eye (52) by means of another quick connector (60). A weight holder (12) is connected to an eye (56) on the second pulley block (16) by means of another quick connector (60). An engagement device is connected to the eye (78) on the other end of the line by another quick connector (60). The engagement device may be a baseball (88) with an extension length of line (86) or a baseball rotatably mounted within a yoke. Alternatively, it may be a cross bar (110) or ankle band (122).
The apparatus may be used for physical therapy and rehabilitation after injury or surgery, and also for physical training, such as for example in instructing a baseball player in the proper throwing technique.
