Instructions
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.
Seated Flat Bench Leg Pull-In
Sit on a bench with the legs stretched out in front of you slightly below parallel and your arms holding on to the sides of the bench. Your torso should be leaning backwards around a 45-degree angle from the bench. This will be your starting position.
Bring the knees in toward you as you move your torso closer to them at the same time. Breathe out as you perform this movement.
After a second pause, go back to the starting position as you inhale.
Repeat for the recommended amount of repetitions.
