A certified personal trainer shares four standing moves that target your core after 50.
For many adults over 50, shrinking your midsection can feel frustrating. Even with regular exercise and healthy weight management, it may seem like stubborn belly fat just won’t go away. That’s because as you age, hormonal changes, reduced muscle mass, and how your body distributes fat can all contribute to weight gain.
Research shows that aging is associated with higher abdominal fat and reduced lean muscle mass, both of which can affect the appearance and strength of your stomach. At the same time, weakening of your deep abdominal muscles can reduce your body’s ability to stabilize and support your lower stomach.
So if you’re in your 50s and wondering what you can do to shrink your apron belly, we’re here to help. We spoke with James Bickerstaff, CPT, a personal trainer at OriGym, who shares four of the best standing exercises designed to engage multiple muscle groups at once while forcing your core to stabilize your body. Compared to crunches and machine-based workouts, these moves are also better for helping improve balance, coordination, and functional strength, all of which are fundamental for healthy aging and weight loss.
“These movements train the abdominal muscles to stabilize the spine and control the pelvis,” Bickerstaff explains. “That’s important for strengthening the muscles that support the lower stomach and improving overall core function.”
Read on for the exercises and detailed step-by-step instructions. Then, when you’re finished, check out these 5 Exercises Personal Trainers Recommend for Clients Over 60 Who Haven’t Worked Out in Years.
Standing Knee Drives
Standing knee drives activate your lower abs while engaging your hip flexors and stabilizing core muscles. Since the movement requires lifting your leg while maintaining an upright posture and balance, it forces your abs to stabilize your body throughout the exercise.
How to do it:
- Stand tall with your feet hip-width apart.
- Place your hands on your hips or hold a chair for balance.
- Engage your core by tightening your abdominal muscles.
- Drive one knee upward toward your chest while keeping your torso upright.
- Pause for one to two seconds at the top of the movement.
- Slowly lower your foot back to the floor with control.
- Repeat the movement with the opposite leg.
- Perform 3 sets of 12 to 15 reps per leg. Rest for 30 to 45 seconds between sets.
Standing Cross-Body Crunch
Standing cross-body crunches combine rotation with knee lifting, allowing your obliques (side abs) to work together with your lower abs. Rotational movements like this can help strengthen the muscles responsible for stabilizing the torso and controlling twisting movements.
“This targets your obliques and lower abdominals at the same time, helping tighten the entire waistline,” says Bickerstaff. “The twisting motion also strengthens the deep core muscles which can also help flatten the lower stomach area over time.”
How to do it:
- Stand with your feet shoulder-width apart.
- Place your hands behind your head with your elbows pointing outward.
- Brace your core and maintain an upright posture.
- Lift your right knee toward your chest.
- Rotate your torso to bring your left elbow toward your raised knee.
- Return to the starting position with control.
- Repeat on the opposite side.
- Complete 3 sets of 12 to 15 reps per side, resting for 30 to 45 seconds between sets.
Standing Pelvic Tucks
This controlled movement targets your deep stabilizing ab muscles. “Pelvic tucks are excellent for activating the deep core muscles that support your lower stomach,” says Bickerstaff. “This controlled movement also strengthens the transverse abdominis, the deep muscle layer responsible for pulling the abdomen inward.”
How to do it:
- Stand up tall with your feet hip-width apart.
- Keep your knees slightly bent and your spine neutral.
- Place your hands on your hips.
- Tighten your glutes and tuck your pelvis forward.
- Draw your belly button inward toward your spine.
- Hold the position briefly for about one to two seconds.
- Slowly return to a neutral standing posture.
- Aim for 3 sets of 15 reps. Rest for 30 to 45 seconds between sets.
Standing March With Core Brace
“This is a low impact movement that strengthens the entire abdominal wall while improving your balance and posture,” says Bickerstaff. “Bracing your core throughout the exercise trains it to stabilise the spine and reduces pressure on your lower abdomen.”
How to do it:
- Stand tall with your feet hip-width apart.
- Engage your core as if preparing for a light punch to the stomach.
- Keep your shoulders relaxed and your chest tall.
- Slowly lift one knee until it reaches about hip height.
- Pause for one to two seconds while maintaining core tension.
- Lower your leg slowly back to the floor.
- Repeat the movement with the opposite leg.
- Continue alternating legs in a marching motion.
- Perform 3 sets of 20 controlled marches (10 per leg), resting for 30 to 45 seconds between sets.
