Most abs workouts are focused on a single motion: contracting your abs as you flex your spine forward, as you do in crunches and situps. But there's more than one way to build your abs, especially because this big muscle group has to work in so many planes of motion.

That's why the third workout in our 30-Minute Abs Workout Program incorporates a few more options. Seated Russian twists will challenge your rotational strength, Swiss Ball crunches will challenge your stability, and one-armed farmer's walks will challenge your abs to hold your torso upright without tilting over, making sure you hit all the muscles you need for that shredded midsection you want.


Complete all three exercises in order. For the first two exercises, you should do 3 to 4 sets; but for the farmer's walk, do 4 to 6 sets depending upon how many sets you feel you can complete without overworking yourself.
