To use the Ab Lounge Ultra, warm up with five to 10 minutes of cardiovascular exercise before sitting in the machine. Making sure you are properly positioned, place your feet on the foot rests, and grab the handles above your head. Exhale while rounding your lower back to perform a curl, and pause for a moment at full contraction before returning to the starting position
- Warm up properly
Perform a light aerobic warm-up for at least five minutes to prepare your body for working out on the Ab Lounge Ultra and to help to prevent injury.
- Position yourself in the Ab Lounge Ultra
Stand next to the Ab Lounge Ultra, and step over the bar that connects the seat to the foot rest. Carefully sit in the seat, and place one foot at a time in the foot rests. With your feet in the foot rests, your knees should be bent at about 90 degrees. Grab the handles above your head.
- Perform a basic jackknife crunch
As you exhale, round your lower back to curl your torso. Pause when you reach peak contraction, and then slowly return to the starting position. Perform each repetition in a slow and controlled fashion. Avoid using momentum in order to force your abdominal muscles to do all of the work.
