Given that I know how tough doing a 10-minute abs workout can be, the idea of tackling a 30-minute one was a little daunting. But if you can push through a longer session like this, then the benefits for your core strength are all the greater.

You don’t need any equipment for this 30-minute abs workout from YouTube fitness trainer Caroline Girvan, although having one of the best yoga mats on hand is helpful if you’re on a hard floor, and it’s a no-repeat workout.
