A variation on using the incline board is the ab ball. This ball has grown in popularity over the last few years because it creates a sense of playfulness for an otherwise tedious routine. The ball is created from a molded plastic so it is durable, yet flexible to use. It is made as a large ball that you lie down over the top of with your feet planted firmly on the ground.
You then perform your sit-ups while lying across the ball. This also helps relieve stress on other regions of the body so your exercise is focused on your abdominal region. To intensify your six pack abs workout you can incorporate various weights as resistance to work the muscles even more. This can be done by holding small dumbbells or by doing some leg lift exercises that use the abs as part of the exercise motion.
