The AB Coaster is an exercise machine designed to help strengthen and tone the body's abdominal muscles. The device consists of a sliding seat assembly, a pair of rails, hand grips and a digital console; once assembled, the all-steel frame has a maximum weight capacity of 300 pounds.
The AB Coaster works by using your body weight to provide resistance as you exercise. As you build muscle strength, you can increase the difficulty of your workout by adding weights to the seat assembly.
Assembly
Step 1
Bolt the rear foot to the bracket located near the rear end of the curved track. Bolt the front foot to the bracket located underneath the front post.
Step 2
Bolt the bracket located near the front end of the curved track to the holes located near the upper end of the front post. Bolt the crossbar located on the lower end of the front post to the bracket located partway up the curved track.
Step 3
Bolt the console unit to the two brackets located at the top of the front post. Cover any exposed bolt heads with the black plastic caps that came packaged with the device.
Step 4
Plug the counter wires into the connection points located on the console and at the end of the crossbar. Place the protective covering over each connection point.
Exercise
Step 1
Stand by the left side of the device and grip the handles. Bend your right leg and lift your right shin onto the far side of the seat.
Step 2
Use the handles to support your body weight as you bend your left leg and lift your left shin onto the near side of the seat. Shift your knees forwards until you are able to hook your feet under the rear edge of the seat.
Step 3
Use your abdominal muscles to perform a forward lift by slowly bringing your knees forward until the seat carriage nears the front end of the rails. Slowly return the carriage to its original location, then repeat the exercise as desired. Maintain an upright posture throughout the exercise.
Step 4
Pull out the locking pin located on the rear of the seat carriage. Twist the seat to the left, then replace the pin; adjust the positioning of both seat and pin until the latter locks into place. Perform a new set of forward lifts, then reset the seat to the right position and perform an additional set of lifts.
Tips and Warnings
- You can develop your own set of exercises by setting the device to “Free-Style Motion” mode. Pull out the locking pin located on the rear of the seat carriage and turn it to the unlocked position; the seat will now swivel freely as you move.
