Abs-olutely a great way to get fitter in less than a half hour a day.

Having a strong core is really good for you.
Your core muscles — including your abs — stabilize your spine, which means you can thank your abs for helping control your head, neck, and pelvis. Your core helps you stand, walk, run, jump, and lift things. So, whether you want to become a better runner or weightlifter, improve your tennis swing, lift luggage and push a vacuum, or just prevent back pain and injury, the stronger your core, the better.
So we asked a fitness expert to put together a 21-day core-strengthening challenge that requires ZERO crunches and only about 15 minutes a day.
Meet Albert Matheny of Soho Strength Lab and Promix Nutrition. He put together a plan to help you get a stronger mid-section in three weeks, using three moves that are safe and effective and way more interesting than just holding a plank.

The important thing, Matheny says, is to complete each day's reps with proper form and control. You're not trying to blow through them as quickly as possible; you're trying to maintain stability and form with every single rep. That means you can take rest as you need it, particularly toward the end of the challenge (when you're doing a lot more at once).
