Sometimes when you brush your teeth, you're so used to brushing in a certain pattern that you end up missing some teeth without realizing it. This can also apply to exercises—especially abs routines. While crunches and squats are classics for a reason, they also don't do much for the sides of your core, aka your obliques. That's why this day of The 30-Minute Abs Workout Program focuses on side-to-side and rotational exercises, so you can ensure you're training all the different parts of your abs.

Directions:

Do all three exercises in order, doing 3–4 sets of each.
