Adjustable friction type exercising device

摘要: A device for exercising the muscles of legs, which simulates striding movement occurs during actual running. body support frame is provided having a pair foot engaging pendulum arms mounted thereon through predetermined arcuate paths travel with an adjustable friction developing mechanism being operatively associated sector to offer resistance movements arms. The offers substantially constant resistive force throughout entire range thrust extension user''s leg and provides unrestricted in opposite direction retraction leg.
