HOW IT WORKS: Total Gym uses a variable-angle incline plane to create exercise resistance by modifying your body weight … the steeper the angle, the more resistance. Down the left side of the chart, you’ll see the various resistance levels  and their corresponding degree of slope. Across the top, you’ll find body weight in 10-pound increments. Simply cross reference your body weight with the incline level to determine the amount of resistance (in pounds) created when the Total Gym is in use without the pulley cables attached. If the pulley cables are used in the exercise, use 50% (or half) of the charted numbers.
