If you spend enough time learning about fitness, you'll come to a clear conclusion: There’s always more to learn. There’s always a better workout. There’s always another exercise variation. (Related: The Anarchy Workout -- one guy lost 18 pounds of fat in just 6 weeks!)

Take the plank: Most people are familiar with it. And they probably know a few variations, like the side plank or the single-leg plank.

But in this video, Gideon Akande, a strength coach and two-time Gold Gloves champion from Chicago, shows you 22 variations of the exercise -- from beginner to brutal. (Akande is also the winner of the 2015 Men's Health Next Top Trainer competition.)

You'll recognize some of these exercises, but others will inspire you to work your core like never before. And all of them will help you get an awesome ab workout.
