how often should you do ab exercises
As mentioned above, your ab muscles are just like other muscles in your body. That means you want to do between 10-16 reps of each exercise for 2-3 sets. If you've been doing abs for a while and find that you're not fatigued at the end of each set: Check Your Form. Don't use momentum or other body parts (like your neck or your hip flexors) to help you.
