“Hit me” isn’t just something you say in a card game. We’ve all encountered someone wanting to show off their abs, who then braces their stomach for impact while you wallop them. In boxing, a solid core isn’t just about taking a hit, though. It’s also about having the power to throw a punch, which, incidentally, also comes from your core. That’s why you can count on a boxer’s abs workout to deliver a core routine that’s both challenging and functional.

“One of the first things you realize when you learn how to throw a punch is that the strength of your arms doesn’t matter nearly as much as the strength of your legs, core, and posterior chain,” says former professional boxer Ed Latimore. “The stronger your core, the more effectively you’re able to transmit the force generated by your legs.”

Your abs simply existing doesn’t do the job, though. The proper movement of your core is what translates the power from your legs into your punch.

“The path of transmission is the core, but the method of transmission is the twisting motion done by your core, and strong core allows you to effectively transfer force from your legs via the twisting motion of your internal obliques, serratus, and latissimus dorsi muscle,” Latimore says.

A strong core has defensive benefits, too. It “provides a better center of balance, which makes it easier to control your body quickly over the short distances that optimize slipping, bobbing, and weaving around punches,” says Latimore.

So how do you harness the power of the core? You’ll need the muscular infrastructure, but you also need to know how to engage the muscles, and put it all together into one smooth motion. That’s why in this new boxer’s abs workout from Rumble boxing instructor and Well+Good’s Trainer of the Month Club instructor Olivia Platania, some of the moves contain punches, or are exaggerated versions of things you’d already do in the ring—such as a squat (or duck) with a standing, twisting crunch.

The way to get the most out of these moves is by engaging your abs. Platania’s cue for this is to “pull your core into your spine.” But what does that actually mean?

“You’re going to hear me say that a lot today—‘belly button to spine,’” Platania says. “Not vacuum in, but I do want you to think, embrace it and protect your spine, right?” Understanding how to protect that spine (and thus, engage your core) comes down to tuning in to real-world scenarios in the ring.

“You want to think about creating a shield around yourself, right?” Platania says. “So if I get hit, I know how to tighten up and I know how to protect myself.”

Get that core ready to throw and take a punch with this 14-minute workout. You can follow along in the video above, or do the routine on your own with the description below.

A boxer’s abs workout

Format: A combination of standing, seated, and laying down abs moves done with the assistance of light weights.

Equipment needed: A place to lay down and two light weights. Platania uses brass knuckles, but if for some reason you don’t have a pair of those lying around, you can use small dumbbells, water bottles, cans of peas, or whatever you have on hand.

Who is this for?: Anyone looking for an abs workout to improve core strength.
