We get it: Regular old sit-ups and crunches can be boring. But sometimes the amount of core exercises—and equipment you can use for them—can get overwhelming. But you don’t need an entire room in your house filled with dumbbells, kettlebells, bands, and the like. To get an effective core workout, all you need is a medicine ball.

“Medicine balls are a useful tool—they’re very dynamic, and they generate a lot of power,” Noam Tamir, C.S.C.S., owner of TS Fitness How to Run More Consistently.

A strong core is essential for runners, since it stabilizes our entire body and gives us the power to keep driving our body forward.

Tamir created a four-exercise med ball circuit to help strengthen your core so you can attack your runs more effectively.

Run a Faster 5K with Run/Walk Intervals: Perform these four exercises as a circuit, moving from one to the next with no rest in between. The number of times you repeat this circuit is up to you, but the more you incorporate it into your routine, the more repeats you’ll be able to do.

Lie faceup on an exercise mat or the floor in a bent-knee position, arms out at your sides. Place left foot on top of med ball and right foot in the air. Lift hips upwards off the floor by engaging your glutes and abs. At the same time, press left foot into the med ball for more stability. Lower yourself back to the starting position. Repeat on the right side. Alternate sides for 10 to 15 reps total.

Make sure to engage core throughout the entire movement. Repeat for 10 reps total.
