Abstract:

The invention comprises a martial arts training apparatus which resembles in movement and function a human leg, particularly in response to a well executed low kick. Leg 10 is mounted to a base 9 upon a bracket 12 above a floor 11 upon which the martial arts trainee stands. The leg comprises an upper leg 20, a lower leg 21 and an extendable foot 47. Upper leg 20 and lower leg 21 are connected by cable 31 and spring 32. A properly executed low kick to leg 10 will cause the leg to "break", pivoting lower leg 21 and upper leg 20 about lower ball 22, and upper leg 20 about upper ball 19 in base 9.
