How Much Exercise Should I Do? (UK Guidelines Explained)
A question I get asked a lot is: “How much exercise should I actually be doing each week?”
Luckily, we don’t need to guess. The UK Chief Medical Officers have set out minimum activity levels for adults and older adults. And while these are “minimums” (not maximums), most people aren’t even close to hitting them.
So, let’s break it down — in plain English.
The UK Minimum Activity Levels for Adults and Older Adults
Here’s what’s recommended:
At least 150 minutes of moderate activity per week
Your heart rate is up, breathing a little harder, but you can still talk reasonably easily. Examples: brisk walking, cycling, swimming.
OR at least 75 minutes of vigorous activity per week
Breathing fast, difficulty talking — like running, football, or a hard HIIT session.
Build strength on at least 2 days a week
This keeps your muscles, bones and joints strong. It could be weights, resistance bands, Pilates, yoga, or even carrying heavy shopping bags.
Minimise sedentary time
Break up long periods of sitting with short bursts of movement.
Older adults: add balance training (like Tai Chi, dance, or bowls) at least 2 days a week to reduce the risk of frailty and falls.
Why Consistency Matters (Especially for Back Pain)
Meeting these minimums isn’t just about fitness or weight management. They’re also a crucial line of defence against stiffness, weakness, and back pain.
Strength work supports your spine, hips, and core.
Regular movement keeps joints mobile and reduces stiffness.
Consistency is key. If you go on holiday and spend a week being active (walking, swimming, cycling) but miss your strength or vigorous work, that’s usually fine. But longer breaks — two weeks or more — start to undo your progress and can open the door to aches, stiffness, and recurring back issues.
Remember: you can take a holiday from work, but not from your health.
Beyond the Basics: What ACSM Recommend
The UK guidelines are clear on cardio and strength. The American College of Sports Medicine (ACSM) go further, suggesting that all adults (not just older ones) also benefit from balance and flexibility training.
This isn’t just about avoiding falls — it’s about moving more freely, improving quality of life, and keeping your body resilient at every age.
The Proven Benefits of Physical Activity
The infographic makes it clear: being active isn’t just about feeling good — it literally reduces your risk of major illness:
40% lower risk of type 2 diabetes
35% lower risk of cardiovascular disease
30% lower risk of falls and depression
25% lower risk of joint and back pain
20% lower risk of colon and breast cancers
And beyond the numbers, regular activity also:
Improves sleep
Maintains a healthy weight
Manages stress
Improves quality of life
Every minute counts — and it’s never too late to start.
Where Pilates Fits In
Pilates is one of the simplest ways to cover several of these bases:
Builds strength (especially in your core, glutes, and postural muscles).
Improves balance and control, which ACSM highlight for all adults.
Enhances flexibility — helping you move more comfortably and reduce stiffness.
On its own, Pilates won’t cover your 150 minutes of cardio, but combine it with walking, swimming, or cycling and you’re ticking off nearly every guideline box.
Takeaway
If you’ve been asking yourself “How much exercise should I do?” the answer is clear:
150 minutes of moderate activity or 75 minutes of vigorous activity per week, plus 2 strength sessions, and regular breaks from sitting.
Start by building up to hitting the minimums — you’ll feel the benefits in your energy, your long-term health, and very likely your back too.
And remember: a short break, like a week away, is fine if you stay generally active. But don’t let it stretch beyond that. Consistency is what protects your body — you don’t get to take a holiday from your health.
