Modern life is the real obstacle to fitness, not motivation
Most Namibians want to be healthy. They buy protein shakes, join gyms, and meal-prep on Sundays. Yet the data tells a sobering story: obesity rates are climbing, healthy life expectancy is falling, and frustration is rising. The problem, according to sport and exercise scientist Dr Ash Cox, is not a lack of willpower. It is the environment we have built around ourselves.
In the UK, the 2024 health survey for England found that 66 per cent of adults were overweight or living with obesity, up from 53 per cent in 1993. Healthy life expectancy has also declined in recent years, despite an ageing population. Sport England data shows that nearly two-thirds of adults now meet official physical activity guidelines, a record high. So people are moving more, yet getting sicker. Why?
Why exercise alone is not enough
Dr Cox points to a fundamental mismatch between human biology and modern living. For most of history, humans had to move to survive: hunting, gathering, and seeking shelter. Today, we sit at desks, drive everywhere, and order food from apps when we are too tired to cook. Movement has become optional, and the default is stillness.
The cost-of-living crisis compounds the problem. Many people work longer hours for less disposable income, leaving little time or money for gym memberships and sports clubs. When budgets tighten, fitness expenses are often the first to go.
The supermarket trap: cheap food, poor nutrition
Even when people do make it to the supermarket, they face a barrage of ultra-processed snacks and packaging covered in vague health claims. In a tight economy, the most affordable food is often energy-dense and nutritionally poor. As Dr Cox puts it:
People participating isn't necessarily the issue. It's the environment.
None of this is meant to blame individuals. We are all playing a game with a significant handicap. But there are ways to push back, even without waiting for systemic change.
A playful approach to movement
Instead of treating exercise as punishment or a chore, Dr Cox and other experts recommend weaving movement into daily life with intention. The evidence is clear: habitual physical activity delivers the biggest health wins, not just dedicated workout sessions.
- Dance while cooking dinner
- Take the stairs with some intensity
- Walk the school run on foot
- Balance on one leg while brushing your teeth
- Play active games with your children
Dr Cox advises:
All movement adds up. The biggest wins come from habitual physical activity. Put more movement into your life, and go about it with more intent.
What about diet?
The nutritional advice is refreshingly simple: prioritise fruits, vegetables, and whole foods that your grandparents would recognise. Nothing puritanical, just a return to basics. In a world where complexity sells, the most effective recipe for better health is often the most straightforward.
Frequently asked questions
Is motivation the main barrier to fitness?
No. Research and expert opinion suggest that environmental factors, such as sedentary jobs, food environments, and economic pressures, play a larger role than individual motivation.
How much exercise do I actually need?
Official guidelines recommend at least 150 minutes of moderate activity per week, but any movement counts. Short, frequent bursts of activity throughout the day can be just as effective as longer sessions.
Can I improve my health without joining a gym?
Yes. Walking, stair climbing, and active play are all effective. The key is consistency and adding intensity where possible.
For Namibians looking to improve their health, the message is clear: stop blaming yourself, start changing your environment, and embrace movement as a joy, not a punishment.
