Age Is Just a Number

Your birthday tells one story. Your daily life helps write another.

What would you train for if the goal was not to look younger, but to keep living more fully?

Picture a living-room debate. LeBron is on television, and our imaginary armchair expert has questions.

“Whatever that man is taking, I need some.”

“Taking his training seriously?” somebody replies.

Silence. Then: “Pass me the remote.”

We investigate the older athlete’s secret while overlooking the younger spectator’s routine.

In February 2026, LeBron James became the oldest NBA player to record a triple-double, aged 41 (NBA, 2026). Closer to home, the Kamloops 2026 55+ BC Games, September 8–12, offer another picture of later life: participation, competition, and community. NBA.com

Meanwhile, somewhere, a 29-year-old has retired from recreational football because “the body isn’t what it used to be.”

Neither is the amount of football it gets to play.

But this is not an invitation to compare your knees with an elite athlete’s. It is an invitation to question what you have already decided about yours.

Your birthday is information, not an instruction to stop.

The number is real. The verdict is negotiable.

Chronological age counts years. Biological ageing describes changes in our cells and systems. Functional capacity asks a practical question: what can you actually do?

These overlap, but they are not identical.

A 47-year Swedish study of 427 people found aerobic capacity and muscular endurance generally peaked between 26 and 36, then declined. However, becoming active in adulthood was associated with better performance (Westerståhl et al., 2025). Wiley Online Library

Ageing is not imaginary. Neither is the possibility of improvement after your statistical “peak.”

Improving from your own starting point does not require becoming biologically 25. That distinction matters: we are building capacity, not negotiating with the birth certificate.

Past your peak does not mean past your potential to improve.

Is it ageing or a very long off-season?

Consider a familiar life upgrade: playground to classroom, classroom to office, office chair to car seat, car seat to sofa.

More convenience. Fewer reasons to move.

Then we turn 40 and launch an investigation into the birthday cake.

Think about what changes between school and middle age. Playing outside can become commuting. Walking between classes becomes sitting between meetings. Then the weekend arrives, and recovery means barely leaving the sofa.

Eventually, we blame the candles for everything.

In the small Dallas Bedrest study, three weeks of bed rest at age 20 reduced physical work capacity more than the following 30 years of ageing did in those same five men (McGuire et al., 2001). PubMed

That is not a universal formula. It is a striking demonstration that disuse can have powerful effects independently of birthdays.

Now for the encouraging part: in another small study, nine frail participants averaging around 90 completed eight weeks of supervised resistance training. Their tested strength increased by 174% on average (Fiatarone et al., 1990). PubMed

The body can lose practice without losing every possibility.

The real prize is not looking younger

It is carrying groceries, managing stairs, joining an outing, or getting up from a chair more easily.

In the LIFE randomized trial, 1,635 sedentary adults aged 70–89 received either structured physical activity or health education. Over about 2.6 years, the exercise programme reduced the risk of losing the ability to walk 400 metres (Pahor et al., 2014). JAMA Network

No filter. No “reverse your age” powder. A meaningful difference in everyday freedom.

Bone health deserves attention too. The LIFTMOR trial found that twice-weekly, closely supervised resistance and impact training improved bone density and function in postmenopausal women with low bone mass (Watson et al., 2018). Wiley Online Library

That supports appropriately coached loading not copying a stranger’s jump challenge when you have osteoporosis.

Train for the life you want access to, not just the age you want mistaken for.

Same birthday. Different starting lines.

A teenager juggling school, a nurse finishing night, a parent managing childcare and a retiree on a fixed income need different plans.

“Everyone has the same 24 hours” is often said by someone whose laundry apparently folds itself.

Socioeconomic disadvantage was associated with poorer walking performance in research involving over 109,000 adults. Health opportunities are not evenly distributed (Stringhini et al., 2018).

A wealthy retiree with professional support and a cleaner working two jobs do not have identical opportunities. Neither do a new parent, a desk worker, and someone managing chronic illness.

So “just stop being lazy” is not a health strategy. It is a slogan that has never arranged childcare.

For the desk worker, start by protecting movement breaks. For the shift worker, choose sessions that do not steal needed sleep. For the parent, explore shorter home workouts. For someone returning after illness, rebuild with appropriate guidance.

Illness and disability are not evidence of insufficient effort. The plan should respect the person, not punish them for lacking somebody else’s resources.

Personal responsibility works better with practical support than public judgement.

Build a week your future self can use

Rather than copying an athlete’s entire schedule, assemble the essentials.

For adults, build toward at least 150 minutes of moderate aerobic activity weekly and strength training on two days. Start below that when necessary; some activity is better than none. Include balance work as you get older and break up prolonged sitting (Canadian 24-Hour Movement Guidelines). CSEP Guidelines

Practically, that might mean two manageable strength sessions, walks spread across the week and supported balance practice beside a sturdy counter. Progress gradually, rather than trying to repay ten inactive years in one Saturday.

Protect sleep and eat enough to support training, including protein-rich foods such as beans, eggs, tofu, yoghurt or fish. Recovery belongs in the plan—not somewhere after everything else (Bauer et al., 2013). PubMed

Consistency is not doing the most. It is finding enough that you can keep doing.

Keep something to look forward to

A review of 148 studies linked stronger social relationships with better survival. Connection belongs in the health conversation too (Holt-Lunstad et al., 2010). PLOS

Learn the dance. Join the walking group. Try the game without demanding to be good immediately.

The 55+ Games matter beyond medals: they offer something to practise, people to meet, and another reason to show up. You do not need to turn every hobby into a longevity protocol. Sometimes enjoying your life is the point.

Retirement from work does not require retirement from curiosity.

What “fitness as a lifestyle” means here

At CraftFit, we start with the life someone wants to keep participating in. Then we shape movement, strength, nutrition habits and recovery around their current capacity and circumstances.

For one person, progress is competing. For another, it is returning to an activity they thought they had lost.

“Age is just a number” should not mean ignoring biology. It should mean refusing to let one number explain everything.

What would you try next if your birthday were a starting point not a stop sign?
