A “stomach apron” refers to the accumulation of extra fat in the lower abdominal area, often noticeable after the age of 50. According to Karen Ann Canham, the CEO and founder of Karen Ann Wellness, this persistent area of fat results from a slower metabolism, hormonal changes, and the natural decline in lean muscle mass, known as sarcopenia. Engaging in standing core exercises can effectively activate the deeper stabilizing muscles, while simultaneously working the glutes and legs. We consulted with experts who recommended six standing core routines designed to firm and sculpt your stomach apron after 50—no need for floor exercises.

What Makes Standing Core Routines Effective?

“In contrast to traditional crunches or sit-ups, which focus solely on the abdominal muscles while lying down, standing core exercises engage the entire midsection, hips, and lower back,” explains Mr. America Jason Kozma, CPT, from Santa Monica Personal Training. “This approach not only firms the abdominal region but also enhances balance, posture, and functional strength—an important aspect of maintaining an active lifestyle as one ages. Standing workouts are beneficial for people who may find it challenging to get down to the floor and back up. Additionally, these exercises often pose a lower risk to the neck and spine, which can become more delicate beyond middle age.”

Standing movements specifically engage the deep core muscles, which is crucial for tightening and toning your midsection.

“Standing core workouts typically involve the simultaneous engagement of multiple muscle groups, potentially leading to increased calorie burning and a more functional training experience,” states Caine Wilkes, an Olympian and certified USA weightlifting coach at Garage Gym Reviews. “For many individuals, these exercises may seem more approachable and sustainable than solely relying on crunches or sit-ups, particularly after reaching the age of 50.”
