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.
Flat Bench Lying Leg Raise
Lie with your back flat on a bench and your legs extended in front of you off the end.
Place your hands either under your glutes with your palms down or by the sides holding on to the bench. This will be your starting position.
As you keep your legs extended, straight as possible with your knees slightly bent but locked raise your legs until they make a 90-degree angle with the floor. Exhale as you perform this portion of the movement and hold the contraction at the top for a second.
Now, as you inhale, slowly lower your legs back down to the starting position.
Verdict
Both exercises target the abdominals. Ab Crunch Machine is a intermediate exercise using machine, while Flat Bench Lying Leg Raise is beginner and uses bodyweight. Choose Flat Bench Lying Leg Raise if you're looking for a more accessible option, or Ab Crunch Machine for a greater challenge.
