Ab Crunch Machine vs Bosu Ball Cable Crunch With Side Bends

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.

Connect a standard handle to each arm of a cable machine, and position them in the most downward position.

Grab a Bosu Ball and position it in front and center of the cable machine.

Lie down on the Bosu Ball with the small of your back arched around the ball. Your rear end should be close to the floor without touching it.

With both hands, reach back and grab the handle of each cable.

With your feet positioned in a wide stance, extend your arms straight out in front of you and in between your knees. Your hands should be at knee level.

Keep your arms straight and in-line with the upward angle of the cable. Elevate your torso in a crunching motion without dropping or bending your arms.

Maintain the rigid position with your arms. Slowly descend back to the starting position with your back arched around the Bosu Ball and your abdominals elongated.

Repeat the same series of movements to failure.

Once you reach failure, keep your abs tight and raise your torso into plank position so your back is elevated off the Bosu Ball.

Lower your arms down to your side; keep them straight. Start doing alternating side bends; reach for your heels! This finishing movement will focus on your obliques.
