Position the Contour CoreBelt -- the abs belt included with the Contour Core Sculpting system -- over your midsection so the black side of the Gel Pad electrode makes contact with your skin. Align the yellow center line with your navel, which should place the outside pads between your lower ribs and hips. Fasten the belt via the clip or hook and loop. Contour recommends a snug but not overly tight fit.
Press the “On/Off” button on the Contour M2 device -- the unit with the LCD screen that serves as the belt's control -- to turn it on. Select the training program of your choice -- such as “Resistance” or “Endurance” -- by using the top two “+” and “-” keys. Press “Select” to make your choice.
Choose your workout level -- a measure of intensity set to Level 1 by default -- by using the “+” and “-” keys. Start with workout Level 1 and choose higher levels over time as you become more comfortable with the CoreBelt. According to Contour, your ideal workout level should feel powerful but not uncomfortable. Press “Select” to confirm the workout level.
Push “Select” one more time when “Upper Body” appears on the LCD screen to begin the muscle stimulation. The CoreBelt automatically starts at intensity level zero. Press the “+” buttons on the left and right side -- which control the pads on the left and right side of your body, respectively -- of the M2 device to gradually increase your intensity level to the maximum.
