Key takeaways
- The transverse abdominis (TVA) is your deepest core muscle, and many people strong in sit-ups still cannot isolate it or make it work properly.
- Marching improves fat loss more effectively than sit-ups because it raises your heart rate and engages your largest muscles, boosting total energy expenditure.
- You cannot lose fat from just your belly; effective fat loss requires cardiovascular movement that increases your overall metabolic output.
- Alternating contraction and relaxation of your abdominal wall, rather than constant tension, addresses bloating and supports better digestive function.
Why Sit-Ups Alone Don’t Work
For people in their 60s, 70s, and beyond, the traditional approach to flattening the midsection falls short. According to fitness experts consulted by Eat This Not That, the size and shape of your abdomen depends on far more than body fat alone. A trainer working with this demographic focuses on body composition, yes, but also on how well the abdominal wall functions, spinal alignment, how your body manages pressure in the abdominal cavity, and what’s happening with digestion and bloating. Three standing exercises address all these factors in ways that sit-ups cannot.
What Makes the Transverse Abdominis Different
Most abdominal training targets the muscles you can see and feel. The TVA operates on a different level entirely.
Anatomy and Function
The transverse abdominis is the deepest of all abdominal muscles. Its fibers run horizontally around your midsection, much like a corset wrapping from front to back. These fibers extend all the way across the front of your abdomen and around to your spine, where they attach. Because they sit below all the other abdominal muscles, they remain mostly invisible and overlooked.
The TVA doesn’t flex your spine the way sit-ups do. Its actual job involves controlling your abdominal wall, stabilizing your trunk, and managing the pressure inside your abdominal cavity. Getting this muscle stronger matters, but so does training the entire abdominal wall to contract, relax, and work in coordination.
Why Most People Miss It
According to Eat This Not That, many clients who consider themselves relatively strong and can perform numerous traditional abdominal exercises struggle to isolate and control the TVA when a trainer asks them to focus on it specifically. Raw strength in conventional ab work doesn’t guarantee you can recruit this deeper layer. Finding and engaging the TVA requires dedicated attention and the right cues.
Retraining Your Abdominal Wall
The belly roll starts with a simple concept: your abdominal wall should move, not stay locked tight all the time.
The Role of Alternating Movement
For older adults dealing with bloating, constipation, or a belly that feels perpetually distended, more sit-ups won’t address the underlying problem. The solution involves controlled movement of the abdominal wall that creates an alternating pattern of contraction and relaxation, rather than constant tension.
Research supports this approach. According to Eat This Not That, there is evidence that physical activity and abdominal movement can support gastrointestinal motility. While trainers are careful not to claim that an ab exercise fixes digestive problems (which involve many factors), clinical experience shows clients notice a real difference in how their abdomen feels when they get more movement through that region.
How the Belly Roll Works
The belly roll is the primary exercise recommended for retraining this alternating function. It specifically targets the pattern of contraction and relaxation, addressing the distension and bloating many older adults experience. The movement isn’t complicated, but it requires focus and body awareness to perform correctly.
Cardiovascular Movement for Real Fat Loss
Separating the concept of abdominal function from actual fat loss is critical. You cannot spot-reduce fat from your abdomen or anywhere else.
Why Marching Works for Older Adults
Losing fat requires increasing your total energy expenditure. This is where cardiovascular movement enters the program. Marching is a movement that Eat This Not That notes trainers use extensively with older clients because it’s highly adaptable. It safely elevates your heart rate and engages the large muscle groups throughout your body, boosting your metabolic output. This strategy proves much more useful than simply telling someone to do more sit-ups.
How to Modify and Scale
The beauty of marching lies in its flexibility. You can adjust the intensity to match your current fitness level by changing the pace, how high you lift your knees, and how long you perform the movement. Adding different arm movements amplifies the cardiovascular benefit by increasing blood circulation. You can also remove arm movements or reduce knee height if you’re just starting out.
Once you build competency with basic marching, you can layer in abdominal work. The combination of marching plus isolated abdominal engagement creates a movement that addresses multiple goals at once, merging cardiovascular benefit with deep core activation.
The Holistic Approach to Your Midsection
Trainers working with older clients consider three separate but interconnected elements: abdominal function, movement capacity, and body composition. Addressing the midsection means building all three simultaneously rather than focusing on one.
Abdominal function refers to how well your abdominal wall can contract, relax, and coordinate. Movement capacity means you can perform exercises like marching and belly rolls with control. Body composition involves reducing overall body fat through cardiovascular activity and total energy expenditure.
Combining these approaches produces results that single-exercise routines simply cannot match. This framework explains why Eat This Not That featured these standing movements: they target a fuller picture of midsection health than traditional calisthenics.

Frequently Asked Questions
What's the transverse abdominis and why does it matter?
The transverse abdominis (TVA) is the deepest abdominal muscle, with fibers running horizontally like a corset around your midsection. It controls your abdominal wall, stabilizes your trunk, and manages intra-abdominal pressure. Many people strong in traditional ab exercises still struggle to isolate the TVA, which is essential for proper abdominal function.
Can you lose fat just from your belly with the right exercises?
No. You cannot spot-reduce fat from your abdomen or anywhere else. Losing fat requires increasing your total energy expenditure through cardiovascular activity and overall movement, not through targeted abdominal work alone.
How do you modify marching if you're just starting out?
You can adjust marching by changing the pace, how high you lift your knees, and the duration of the movement. You can add or remove arm movements depending on your fitness level. This makes marching scalable for people at any starting point.
