Ab Crunch Machine vs Reverse Crunch

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.

Lie down on the floor with your legs fully extended and arms to the side of your torso with the palms on the floor. Your arms should be stationary for the entire exercise.

Move your legs up so that your thighs are perpendicular to the floor and feet are together and parallel to the floor. This is the starting position.

While inhaling, move your legs towards the torso as you roll your pelvis backwards and you raise your hips off the floor. At the end of this movement your knees will be touching your chest.

Hold the contraction for a second and move your legs back to the starting position while exhaling.

Repeat for the recommended amount of repetitions.
