21 Cable Diagram The diagram below shows the proper routing of the Low Cable (72), the High Cable (73), and the Leg Press Cable (76). The numbers show the correct route for each cable. Make sure that the cables are routed cor- rectly , that the pulleys move smoothly , and that the cable traps do not touch or bind the cables.
Attaching the Lat Bar , Ankle Strap, or Ab Strap The Lat Bar (61), Ankle Strap (10), and Ab Strap (75) can be attached to the cable at the desired pulley station with a Cable Clip (69). For some exercises, the Chain (67) should be connected between the attachment and the cable with two Cable Clips.
Adjusting the Position of the Backrest T o adjust the position of the Backrest (41), first loosen the Adjustment Knob (9). Pull the Knob out as far as possible and slide the Backrest Frame (not shown) to the desired position. Release the Knob so that it snaps into one of the adjustment holes on the Backrest Frame.
24 Tightening the Cables Woven cable, the type of cable used on the weight sys- tem, can stretch slightly when it is first used. If there is slack in the cables before resistance is felt, the cables should be tightened. T o tighten the cables, insert the Weight Pin (39) under the third Weight (26) from the top.
25 This chart shows the approximate weight resistance at each weight station. “T op” refers to the 10 lb. top weight. The other numbers refer to the 10 lb. weight plates. Note: The actual resistance at each station may vary due to differences in individual weight plates as well as friction between the cables, pulleys, and weight guides.
26 Exercise Guidelines THE FOUR BASIC TYPES OF WORKOUTS Muscle Building T o increase the size and strength of your muscles, push them close to their maximum capacity . Y our mus- cles will continually adapt and grow as you progres- sively increase the intensity of your exercise.
27 Rest for a short period of time after each set. The ideal resting periods are: • Rest for three minutes after each set for a muscle building workout. • Rest for one minute after each set for a toning work- out. • Rest for 30 seconds after each set for a weight loss workout.
