Key takeaways
- Holding a hollow hold position for 60 seconds places your core endurance in the top 10 percent for adults over 55.
- Core endurance—sustained trunk stability during activity—supports lifting, carrying, and getting off the floor.
- Progress from bent-knee or arms-down variations toward the full 60-second hold, prioritizing perfect position over duration.
For adults over 55, a straightforward test can measure core endurance: hold the hollow hold position for 60 seconds. According to Eat This Not That, sustaining this position for a full minute places your core strength in the top 10 percent. The exercise differs from the familiar plank, which is performed standing or prone. The hollow hold takes place on your back, creating a very different physical demand.
What the Hollow Hold Is
Positioning the hollow hold correctly starts with lying flat. Your lower back presses firmly against the floor while your shoulders lift away from it. Your arms extend overhead, and your legs stretch out in front of you, creating maximum distance between your limbs and your center of mass. A body that’s long and extended becomes the challenge here. Everything else follows from this basic position.
Why Core Strength Matters After 55
Your core doesn’t exist in isolation. It provides a stable foundation for your arms and legs during lifting, carrying, climbing stairs, and countless daily movements. A stronger core reduces strain on your joints and cuts injury risk. More importantly, your midsection has to maintain this stability continuously. You don’t brace hard for one moment and then relax. Your trunk stays engaged across extended periods of activity, whether you’re walking the dog, working in the garden, or moving between rooms. The hollow hold specifically trains this sustained tension.
The Mechanics Behind the Movement
How Increasing Distance Increases Demand
Increasing the distance between your arms, legs, and center of mass forces your abdominal muscles to work exponentially harder. Your rectus abdominis (the front abdominal muscle visible under the skin) handles visible work, while deeper abdominal layers stabilize your trunk against gravity and movement. As you extend your legs, your hip flexors engage. The longer you hold this extended position, the more cumulative fatigue your entire system faces. Yet your job remains the same: keep your lower back pressed down and your shoulders lifted.
What Endurance Actually Measures
Endurance shows up precisely here. With nowhere to hide, fatigue reveals itself. Your legs may begin to inch upward. Your lower back might lift slightly. These tiny breakdowns signal that your core can no longer maintain the position. A full 60 seconds of staying locked in place—lower back planted, shoulders raised, no motion, no creeping—demonstrates core endurance that most people past 55 don’t yet possess.
Progression Through Variations
Four Pathways Forward
If the full hollow hold feels inaccessible, begin with a bent-knee version where your feet stay closer to your body and less distance exists between your limbs and center. An arms-down hollow hold places your arms at your sides rather than overhead, again reducing lever length. A single-leg hollow hold extends one leg while keeping the other bent, offering a middle ground. The full hollow hold, with both arms extended and both legs straight, represents the final challenge.
Your Movement Standard
Your movement standard remains consistent across all variations: lower back pressed to the floor and shoulders lifted. When your back lifts, your set ends, regardless of how you feel. This clarity prevents compromise. You can’t negotiate with yourself about what counts.
Building Toward 60 Seconds
Start with whichever variation allows you to maintain perfect position for 20 to 40 seconds. Perform three sets, resting 45 to 60 seconds between them. This framework introduces the movement without overwhelming your system or forcing you to compromise your form. Most people notice gains quickly, with a 20-second hold often becoming 35 seconds, then 45, within a few weeks of repeated testing. The progression feels tangible and motivating.
Quality always comes before duration. Adding five extra seconds by arching through your lower back teaches your core an unsafe pattern. Instead, stay at a variation level where you maintain your position standard cleanly. Only when you can reliably hold the position well do you either extend time or progress to a harder variation. This patience builds lasting core strength rather than creating the illusion of strength through broken-down position.
Small Details That Amplify Results
A final detail amplifies the movement: point your toes away from your body and actively squeeze your quadriceps. This action prevents your hips from shifting and keeps your legs’ weight managed effectively. Many people allow their legs to go slack partway through, immediately destabilizing the entire hold. Engaged legs and tight quads lock your system in place.
Serious Core Endurance at Any Level
According to Eat This Not That, reaching a solid 60 seconds with good position represents serious core endurance after age 55. If you’re building toward that goal, each cleaner and longer hold counts as progress. The hollow hold offers something many exercises lack: a simple, measurable target, multiple entry points for beginners, and a clear path of advancement. These qualities make it worth the effort.

Frequently Asked Questions
What is a hollow hold and how do you perform it?
Lie on your back with your lower back pressed to the floor and shoulders lifted. Extend your arms overhead and legs away from your body, creating distance between your limbs and center of mass. Maintain this position without your lower back lifting or shoulders sagging.
Why does core endurance matter after age 55?
Your core provides stability for lifting, carrying, and moving through daily life. Since you need sustained trunk stability across extended activities like walking and gardening, training core endurance directly supports these real-world demands.
How should you progress toward holding a hollow hold for 60 seconds?
Start with a bent-knee or arms-down variation where you can maintain perfect position for 20 to 40 seconds. Perform three sets with 45 to 60 seconds rest between them. Only increase duration or progress to a harder variation once you can hold your current variation reliably.
