Ab Crunch Machine
Select a light resistance and sit down on the ab machine placing your feet under the pads provided and grabbing the top handles. Your arms should be bent at a 90 degree angle as you rest the triceps on the pads provided. This will be your starting position.
At the same time, begin to lift the legs up as you crunch your upper torso. Breathe out as you perform this movement. Tip: Be sure to use a slow and controlled motion. Concentrate on using your abs to move the weight while relaxing your legs and feet.
After a second pause, slowly return to the starting position as you breathe in.
Repeat the movement for the prescribed amount of repetitions.
Knee/Hip Raise On Parallel Bars
Position your body on the vertical leg raise bench so that your forearms are resting on the pads next to the torso and holding on to the handles. Your arms will be bent at a 90 degree angle.
The torso should be straight with the lower back pressed against the pad of the machine and the legs extended pointing towards the floor. This will be your starting position.
Now as you breathe out, lift your legs up as you keep them extended. Continue this movement until your legs are roughly parallel to the floor and then hold the contraction for a second. Tip: Do not use any momentum or swinging as you perform this exercise.
Slowly go back to the starting position as you breathe in.
Repeat for the recommended amount of repetitions.
