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.
Barbell Rollout from Bench
Place a loaded barbell on the ground, near the end of a bench. Kneel with both legs on the bench, and take a medium to narrow grip on the barbell. This will be your starting position.
To begin, extend through the hips to slowly roll the bar forward. As you roll out, flex the shoulder to roll the bar above your head. Ensure that your arms remain extended throughout the movement.
When the bar has been moved as far forward as possible, return to the starting position.
