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.
Barbell Ab Rollout
For this exercise you will need to get into a pushup position, but instead of having your hands of the floor, you will be grabbing on to an Olympic barbell (loaded with 5-10 lbs on each side) instead. This will be your starting position.
While keeping a slight arch on your back, lift your hips and roll the barbell towards your feet as you exhale. Tip: As you perform the movement, your glutes should be coming up, you should be keeping the abs tight and should maintain your back posture at all times. Also your arms should be staying perpendicular to the floor throughout the movement. If you don't, you will work out your shoulders and back more than the abs.
After a second contraction at the top, start to roll the barbell back forward to the starting position slowly as you inhale.
Repeat for the recommended amount of repetitions.
