Abstract: An interactive aerobic exercise machine has a support frame assembly with two parallel, spaced apart vertical frames, an obstacle rod rotatably mounted on each vertical frame, and a motor for rotating each obstacle rod at selected rotation speeds. The rotating obstacle rods allow a user to exercise a variety of different muscles while the user is also developing depth perception, timing, reaction, agility, coordination, and aerobic fitness. In a particular embodiment, each motor is slidably mounted on the vertical frame for vertically positioning the obstacle rods at a variety of vertical locations. The machine may further include a crank rod connected to the motor and a pivot block assembly connecting the crank rod to the obstacle rod, where the pivot block assembly permits the obstacle rod to move in any direction in response to encountering an obstacle to prevent injury to a user.
