If you’re working out at home right now and looking for ways to mix up your routine, consider adding an exercise ball into the mix. (If you don’t have one, they’re a little easier to come by online than a set of dumbbells.) Often underestimated, exercise balls are an extremely versatile piece of equipment that can come in handy for many types of workouts, especially for abs.

“A stability or exercise ball is a great piece of equipment you can use to create a dynamic workout virtually anywhere,” says Lindsey Clayton, senior instructor at Barry’s in New York City and cofounder of the Brave Body Project. “Because of the ball’s soft, bouncy quality, when you exercise with it, it will challenge you to maintain proper alignment, stability, and strength when performing movements. It’s like taking your basic abs moves and kicking it up a notch.”

It makes sense that you’d want to up the intensity of your core workouts, since targeting all those muscles helps maintain your position on the bike and power you up hills.

That’s why Clayton came up with this six-move exercise ball workout that’ll work your abs and incorporates just an exercise ball, so you can reap all of its unique benefits and switch up your regular routine to build a strong core—no gym required.

How to use this list: The exercises below are all demonstrated by Clayton herself so you can learn the proper form. Perform as many reps as possible of each for 1 minute before moving on to the next. Rest for one minute between rounds. Compete 3 rounds.
