BUTTERFLY ARM (lbs.) PRESS ARM (lbs.
CABLE DIAGRAMS The cable diagrams below show the proper routing of the Right Stack Cable (68), the Press Cable (69), the Leg Lever Cable (70), the Lat Cable (71), and the Ab Cable (72). Use the diagram to make sure that the cables and the cable traps have been assembled correctly. If the cables have not been correctly routed, the weight bench will not function properly and damage may occur. The numbers show the correct route for each cable. Make sure that the cable traps do not touch or bind the cables.

MAINTENANCE Make sure all parts are properly tightened each time the weight system is used. Replace any worn parts immediately. The weight system can be cleaned with a damp cloth and a mild, non-abrasive detergent. Do not use solvents. TIGHTENING THE CABLES Woven cable, the type of cable used on the weight system, can stretch slightly when it is first used. If there is slack in the cables before resistance is felt, the cables should be tightened.
EXERCISE GUIDELINES THE FOUR BASIC TYPES OF WORKOUTS PERSONALIZING YOUR EXERCISE PROGRAM Muscle Building To increase the size and strength of your muscles, push them close to their maximum capacity. Your muscles will continually adapt and grow as you progressively increase the intensity of your exercise. You can adjust the intensity level of an individual exercise in two ways: • by changing the amount of resistance used • by changing the number of repetitions or sets performed.
slowly as you stretch and do not bounce. Ease into each stretch gradually and go only as far as you can without strain. Stretching at the end of each workout is an effective way to increase flexibility. 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 workout. • Rest for 30 seconds after each set for a weight loss workout.
