5 Standing Core Moves That Flatten Your Stomach After 40

Flatten and firm your belly with these simple standing core moves that are expert-approved.

After you hit 40, muscle mass starts to naturally decline if you’re not consistent with strength training. This, in turn, reduces daily calorie burn and promotes fat accumulation in the belly area. With age, insulin sensitivity also declines, making major carb spikes much more likely to be stored as dangerous visceral fat—the type that surrounds your internal organs, says Denise Chakoian, Rhode Island certified fitness trainer and owner of Core Cycle and Fitness LaGree. In order to keep your midsection in top shape, Chakoian shares five standing core exercises that flatten and firm your stomach after 40.

Why choose standing core exercises? According to Chakoian, they train the muscles the way you utilize them in daily life—that strength carries over to chores, walking, and lifting.

“They load the spine less than many floor moves, which can feel better on the neck, wrists, and lower back,” Chakoian notes. “Standing work also trains balance and hip stability, key areas that slip after 40 and protect against trips and falls. Because you can pair them with light weights or steps, they raise the heart rate and burn more energy in less time. They also encourage better posture and breathing mechanics, which helps the core and pelvic floor work together.”
