Prehabilitation Before Surgery: Why Fitness Matters Now

Most people start exercising after something goes wrong. A diagnosis, a fall, a surgery date on the calendar. Denise did it the other way around.
Before she needed a knee replacement, she was already a regular in Thrive Healthcare's Legends Programme, the physiotherapist-led fitness class for adults 50 and over. She wasn't training for a surgery she didn't know was coming. She was training to stay strong, mobile, and independent. When the surgery did come, that training became the reason her recovery went the way it did. She was back in Legends classes in under six months.
Her story is a useful case for a question worth asking well before you need the answer: why wait until your body forces the issue to start building your fitness base?
What Prehabilitation Actually Means
Prehabilitation, often shortened to "prehab," is the practice of building strength, mobility, and cardiovascular fitness before a planned medical event, most commonly surgery. The principle is straightforward. A body that enters surgery stronger has more capacity to recover from it.
In orthopaedic care, this connection is well established. Patients who go into a joint replacement with better baseline strength and mobility tend to regain function faster and rely less on high levels of support during recovery. The surgery is the same procedure either way. What differs is the starting point.
Denise's knee replacement is a clear example. She didn't begin building strength the week before surgery. She had been doing it for years, through regular Legends classes, without knowing a surgery was ahead of her. That distinction matters. Prehabilitation works best when it isn't a last-minute scramble but an ongoing habit.
Why We Train Now, Not Just When Something Goes Wrong
There are four reasons to build a fitness base before you need one, and none of them require a diagnosis first.
Ageing. Strength, balance, and mobility decline gradually with age unless something actively works against that decline. Waiting until a fall or a diagnosis to address this means starting from a weaker position than if the work had already begun.
A surgery you don't yet know you'll need. Denise didn't plan around her knee replacement. Nobody does. Joint replacements, cardiac procedures, and other planned surgeries often arrive with only a few weeks or months of notice. If your fitness base is already in place when that notice comes, prehabilitation has effectively already started.
Caring for grandchildren. Picking up a toddler, keeping up on a walk, getting down to the floor and back up again. These are physical demands that grandparents want to meet without hesitation. A stronger, more mobile body makes that possible without a second thought.
Independence. The ability to manage stairs, get in and out of a car, carry groceries, and move through daily life without assistance is built over years, not restored overnight. It's far easier to maintain independence through consistent training than to try to rebuild it after a setback.
What a Physiotherapist-Led Fitness Class Adds
Not every fitness class is appropriate for someone managing a chronic condition or building toward a future surgery, and that's where the Legends Programme differs from a standard gym class.
Legends is led by AHPC-registered physiotherapists, not personal trainers. That distinction means classes are structured to safely manage conditions like cardiac issues, osteoporosis, Parkinson's, and stroke recovery, while still delivering real strength and conditioning work. Running since 2019 with 150 or more active members, the programme has been recognised as a finalist for the Asia Pacific Eldercare Innovation Awards.
For someone like Denise, this meant her pre-surgery training wasn't generic. It was appropriately loaded, monitored by a physiotherapist, and adjusted around her body, which is part of why her post-surgical recovery went as smoothly as it did.
How to Start Building Your Fitness Base
You don't need a diagnosis, a surgery date, or a specific goal to start. You need a starting point.
A trial class is the simplest way to find out where your body is right now and what a physiotherapist-led programme looks like in practice. From there, consistency matters more than intensity. The goal isn't to train as hard as possible. It's to build a base that holds up when life asks something of your body, whether that's a flight of stairs, a grandchild, or a surgery you didn't see coming.
Denise didn't know she'd need a strong knee before her surgery. She just kept showing up. That's the whole strategy.
