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.
Lower Back Curl
Lie on your stomach with your arms out to your sides. This will be your starting position.
Using your lower back muscles, extend your spine lifting your chest off of the ground. Do not use your arms to push yourself up. Keep your head up during the movement. Repeat for 10-20 repetitions.
Verdict
Both exercises target the abdominals. Ab Crunch Machine is a intermediate exercise using machine, while Lower Back Curl is beginner and uses bodyweight. Choose Lower Back Curl if you're looking for a more accessible option, or Ab Crunch Machine for a greater challenge.
