You sit down in your garden chair after watering the pots, and a few minutes later when you stand up, you feel your weight shift in a way that wasn’t there a few years ago. Nothing dramatic—just a slight wobble, a moment of extra thought before you’re steady. Or you’re reaching across the kitchen counter for a tea bag and notice your stomach muscles don’t engage the way they used to. These small moments add up, and they’re usually the reason someone starts wondering about their core.

Core strength gets talked about a lot, but what it actually means after sixty is more practical than most people realise. It’s not about visible abdominal muscles or holding a plank for two minutes. It’s about being able to get out of a low car without using your hands. It’s about carrying a shopping bag from the supermarket to the car without your back complaining. It’s about feeling steady when you step off a kerb that’s slightly higher than you expected.
A stability ball (also called an exercise ball, Swiss ball, or yoga ball, depending on who you ask) is one of those pieces of equipment that looks simple but does something genuinely useful. It gives you a reason to engage your core throughout the day, without having to think about it as exercise. And for someone in their sixties or seventies who doesn’t have a fitness background, that matters.
In a 2016 clinical study, seniors who practised stability ball exercises for twenty minutes a day, five days a week, showed significant improvements in balance and coordination after just one month.

A stability ball is useful because it forces your body to make small constant adjustments to stay upright—something your core does naturally when you walk or stand, but without the risk of falling. The ball creates a controlled instability that trains the muscles you actually use for balance, posture, and everyday movement.
Why this matters more than you might think
Most people associate core strength with the front of the abdomen—the “six-pack” muscles you see in fitness magazines. But the muscles that matter most for stability as you age are deeper and less visible. The transverse abdominis wraps around your torso like a corset. The multifidus muscles run along your spine, each one connecting two vertebrae. These are the muscles that keep you upright when you’re standing on a bus that moves suddenly, or when you’re carrying something uneven with one hand.
These deep core muscles tend to weaken with age, partly from disuse and partly from spending more time sitting. A 2014 study found that twenty-minute stability ball workouts, five times per week, increased core strength in older adults (Journal of Physical Therapy Science). The improvement wasn’t just about muscle size—it was about coordination. The brain and the core muscles learned to communicate faster, which is exactly what you need when you feel yourself starting to lose balance.
Another study from 2013 showed that eight weeks of stability ball training reduced low back pain by reducing the load on back muscles (PMC study). This makes sense when you think about it: if your deep core muscles are doing their job, your lower back doesn’t have to work as hard to keep you upright.
Getting started safely
Before you buy a ball and start rolling around on it, there are a few things to get right—especially if you have back issues, hip replacements, or balance concerns.
The first step is choosing the right size ball. This isn’t a one-size-fits-all situation. A ball that’s too big or too small will make the exercises harder than they should be and could put unnecessary strain on your joints. The general rule: if you’re under 5’11” (180 cm), go for a 55 cm (22 inch) ball. If you’re over 5’11”, go for 65 cm (26 inch). When you sit on the ball, your knees should be at roughly a 90-degree angle, with your feet flat on the floor and your hips slightly higher than your knees.
Use the ball on a carpet or a non-slip mat, not a polished floor. A ball that slides out from under you is dangerous.
Place a chair within arm’s reach to use as a support if you feel unsteady. This isn’t cheating—it’s sensible.
Begin with exercises that keep you sitting on the ball rather than lying on it or balancing on it. This gives you a chance to feel how the ball moves before you add complexity.
If you have osteoporosis, a herniated disc, or a recent hip or knee replacement, speak to your GP or a physio before using a stability ball. Some movements may not be suitable.
Do not use a stability ball near stairs, sharp furniture edges, or in a doorway. If you fall off the ball—and it happens to most people at some point—you want to land on a clear, soft surface. Inflate the ball to the manufacturer’s recommended pressure; an under-inflated ball is less stable and can cause you to sit at an awkward angle.
If you’re unsure about any of this, a session with a physiotherapist or a qualified instructor who works with older adults can be money well spent. They can check your ball size, show you the basic movements, and spot any issues before they become problems.
What works and what to look for
Not all stability ball exercises are equally useful for someone over sixty, and some are best avoided entirely. The key is knowing which movements target the actual muscles you need for daily life.
When people talk about “low impact” exercise, they usually mean something that doesn’t jar the joints. A stability ball fits that description, but it’s worth being precise about what that means in practice. Sitting on the ball and gently moving your hips in circles is low impact. Bouncing on the ball is not—and it’s unnecessary for core strength. The goal is controlled movement, not momentum.
Here’s a comparison of two common approaches to stability ball training for older adults. The first is seated balance work, which is ideal for beginners or anyone with limited mobility. The second is floor-based core work, which requires more strength and coordination but targets deeper muscles.
| Attribute | Seated balance work | Floor-based core work |
|---|---|---|
| Difficulty level | Low—suitable for complete beginners | Moderate—requires some existing strength |
| Fall risk | Low—chair nearby, feet on floor | Higher—you’re on the floor, harder to get up |
| Key muscles worked | Deep core stabilisers, hips, lower back | Full core, including obliques and rectus abdominis |
| Best for | Building confidence and daily balance | Strengthening the entire trunk |
| Example exercise | Seated hip rotations, seated marching | Stability ball crunch, ball knee raise |
Seated work is where most people should start. Simply sitting on the ball and gently circling your hips in one direction, then the other, engages the deep core muscles without demanding much strength or coordination. A 2019 study found that eight weeks of core training improved balance and core endurance in older adults (PLOS ONE). The seated exercises are the foundation that makes the harder movements possible later.
One exercise that’s particularly useful for people who sit a lot is the seated march. While sitting on the ball, lift one foot a few inches off the floor, then the other, as if you’re marching on the spot. This forces your core to stabilise your torso while your legs move independently—exactly what happens when you walk on uneven ground. It’s a simple movement, but it reveals a lot about how your balance is holding up.
Many people think they need to “suck in” their belly to engage their core. In fact, bracing the core—as if someone were about to gently tap your stomach—activates more of the deep stabilising muscles. A 2014 study confirmed that bracing engages the pelvis, back, and abdomen together more effectively than simply pulling your stomach in.
If you want to try a stability ball at home, a standard ball is fine for most people. The key is to look for one that’s burst-resistant—this means it deflates slowly if punctured rather than popping suddenly. You can find a range of suitable options by searching for burst-resistant stability balls on Amazon UK.
Options worth considering
If you’re ready to try a stability ball, the choice is simpler than you might think. Most balls are made from similar materials and the main differences are size, thickness, and whether they come with extras like a pump or a resistance band. There’s no need to spend a lot. A good-quality ball from a known brand will cost between £10 and £25, and it should last for years.
For someone who wants a straightforward, no-fuss option, a standard 55 cm or 65 cm burst-resistant ball is the place to start. Look for one that includes a pump (some don’t, and buying a pump separately is annoying). The ball should feel firm but not rock-hard when you sit on it—if it bulges at the sides, it’s over-inflated. A few brands offer a thicker material that feels more durable, but for home use, the standard thickness is fine.
If you’re someone who spends long hours at a desk and wants to use the ball as a chair occasionally, there are ball chairs with a weighted base that prevents rolling. These are more expensive (around £50–£80) but they remove the risk of the ball slipping out from under you. The trade-off is that you lose some of the instability that makes the ball effective for core training—you’re sitting on a ball, but it’s not really challenging your balance the same way.
For those who prefer a more structured approach to core work, the AeroPilates Reformer 287 is a home Pilates machine that works the same deep core muscles as a stability ball, but with guided resistance from cords. Reviewers say it’s surprisingly compact when folded and easy to assemble without tools. It’s a bigger investment, but it gives you a clear sequence of movements to follow, which some people find easier to stick with than self-directed ball exercises.
Whichever option you choose, start with five minutes a day. Not ten, not twenty. Five minutes is short enough that you won’t avoid it, and long enough to feel a difference in how your body feels when you stand up from a chair. Once five minutes feels easy, add another minute or two. Consistency matters far more than duration.
Narrowing it down
The right choice depends on what you actually want to do with it, not on which ball looks best in a photo.
If your main concern is balance and feeling steadier on your feet, a standard 55 cm or 65 cm ball is the most direct tool. You can use it for seated balance exercises, hip rotations, and seated marches—all of which train the specific coordination you need for walking on uneven ground or recovering from a stumble. If you’ve already done some tai chi or balance work, the ball will complement that well.
If your main concern is lower back stiffness or discomfort, a ball can help, but it’s worth being careful. Use it for gentle seated movements first, and avoid any exercise that involves lying on the ball until you’re confident your back can handle it. A stretching routine alongside the ball work will give you better results than either one alone.
If you have osteoporosis or have had a spinal fracture, do not use a stability ball without explicit guidance from a physiotherapist or your GP. Some exercises—particularly those that involve bending forward at the spine—carry a risk of compression fractures in weakened vertebrae.
- A stability ball trains the deep core muscles that control balance and posture, not just the surface abdominal muscles you can see in a mirror.
- Start with seated exercises and a chair nearby for support. Five minutes a day, every day, is more effective than longer sessions done sporadically.
- Choose a burst-resistant ball in the right size for your height (55 cm under 5’11”, 65 cm over). If you have back or bone health concerns, get professional guidance first.
Closing thoughts
No piece of equipment is going to fix your balance or strengthen your core on its own. A stability ball is just a tool—a useful one, but it still requires you to sit on it and move. The people who get the most out of it are the ones who treat it as a regular part of their day, not a project they start and abandon after a week.
Your body knows more about what it needs than any article does. If something feels wrong, stop. If an exercise makes you feel better, keep doing it. The ball is a way to explore what your core can still do, not a test you have to pass.
If you’re curious about trying one, a burst-resistant stability ball is a low-cost, low-risk way to find out. Or if you prefer a more guided approach, the AeroPilates Reformer offers a different path to the same end. Either way, the goal isn’t to become a different person. It’s to feel a bit more steady when you stand up from that garden chair.
