I’ve been training clients for nearly 20 years and this is my all-time favorite 10-minute abs finisher to build 360˚ core strength

Couple workout together in a side plank position.

There are three key ingredients to an effective core finisher, according to Chris Cooper, an NSCA-certified personal trainer of nearly two decades.

“First, it needs to incorporate a variety of movements,” he tells Fit&Well. “Next, it should be efficient and challenging. Finally, it should involve exercises that train the core in 360˚—not just the classic six-pack muscles.”
