Helen Mirren has spent decades proving that fitness doesn’t require a gym membership, an expensive trainer, or even an hour of your day.
At 81, the Oscar-winning actress still follows a 12-minute exercise routine she discovered years ago, one designed in the 1950s for women in the Royal Canadian Air Force.
It sounds almost too simple to be effective, but mounting research on short bursts of activity suggests her approach may be more powerful than marathon workout sessions.
And the best part? She’s never even mastered it.

The 12-Minute Routine She’s Never Outgrown
Mirren has never been drawn to elaborate wellness rituals or trendy fitness classes. When asked about staying strong and active, she consistently points to one thing: a small booklet called XBX.
Created by Dr. Bill Orban for women in the Royal Canadian Air Force during the 1950s, the program was designed as a companion to the men’s version, 5BX. The concept was refreshingly straightforward: ten exercises performed in the same order every time, completed in 12 minutes, requiring zero equipment.
Speaking to Woman’s Weekly, Mirren described the routine with characteristic honesty.
It’s an exercise regime that starts from very low and easy, then if you follow it through, it can become quite difficult.
Then she added the detail that makes her commitment even more compelling.
I’ve never gotten past the second level, but it’s a nice exercise program.
According to the same report, this routine is precisely why she’s never felt compelled to join a gym.
What XBX Actually Involves
The XBX program is organized into four charts, each progressively more challenging. The time commitment remains constant at 12 minutes, but repetitions increase as you advance through levels.
Chart one includes these ten foundational movements:
- Toe touches to warm up the hamstrings and lower back
- Knee raises for hip flexor activation
- Lateral raises targeting shoulder mobility
- Arm circles to open the chest and upper body
- Partial sit-ups building core strength
- Chest and leg raises engaging back and glute muscles
- Side leg raises working hip stabilizers
- Knee push-ups for upper body strength
- Leg lifts challenging lower abdominals
- Running on the spot with small hops to elevate heart rate
Chart two, where Mirren says she completes her daily sessions, swaps in more demanding variations such as rocking sit-ups, leg overs and stride jumps.
All you need is a mat and enough floor space to lie down. The key principle: only progress to the next level once your current chart feels comfortable, which is exactly what makes this program sustainable for decades rather than weeks.
Why 12 Minutes May Be More Effective Than Hour-Long Workouts
For years, conventional wisdom insisted exercise only “counted” when performed in lengthy sessions. Recent scientific research has been systematically dismantling that assumption.
A December 2022 study published in Nature Medicine analyzed wrist-tracker data from more than 25,000 adults in the UK Biobank who described themselves as non-exercisers. Researchers, led by Professor Emmanuel Stamatakis from the University of Sydney, followed participants for approximately seven years.
The findings were striking.
Three to four short bursts of vigorous activity daily—about one minute each—were associated with up to a 40% lower risk of death from any cause and from cancer, and up to a 49% lower risk of cardiovascular death.
A few very short bouts totalling three to four minutes a day could go a long way.
That’s what Stamatakis told researchers at McMaster University, which co-led the work. While the study was observational and cannot establish direct causation, it aligns with a broader shift in exercise science: consistency matters more than duration.
How Mirren’s Routine Addresses Age-Specific Needs
Mirren’s 12-minute program also addresses a critical gap many people over 65 miss entirely.
According to CDC guidelines, older adults should perform muscle-strengthening activities at least two days per week, along with exercises that improve balance.
Push-ups, sit-ups and leg raises cover strength requirements. Side leg raises and small hops work directly on balance, reducing fall risk—a leading cause of injury and hospitalization among older adults.
In other words, Mirren’s vintage routine checks every box modern geriatric medicine recommends, without requiring a single piece of equipment or a trip to the gym.
How to Start the XBX Program at Home
If you’re ready to borrow Mirren’s approach, the entry point is refreshingly simple.
Begin with chart one. Keep the same time slot every day—consistency builds the habit faster than intensity ever will. Resist the urge to race through levels; the program is designed to progress gradually, not quickly.
A standard yoga mat provides enough cushioning. A pair of light dumbbells can be added later if you want to increase resistance, but they’re optional for months.
Anyone managing joint pain, heart conditions or recovering from recent injury should consult their doctor before starting any new exercise program.
Pairing XBX With Other Gentle Movement
On busier days, the 12-minute routine pairs beautifully with a daily walk—a habit Jane Fonda credits for staying active at 88.
You can also combine it with a few wall Pilates exercises that work deep core muscles without straining the neck, or morning stretches that loosen stiff joints before the day begins.
The beauty of a 12-minute baseline is that it leaves room for flexibility without abandoning structure entirely.
The Real Secret Isn’t the Exercises
What makes Mirren’s routine genuinely remarkable isn’t its intensity, innovation or difficulty.
It’s the fact that she has kept doing it—at the same pace, without ever mastering it—for decades.
In a fitness culture obsessed with optimization, transformation and the next viral trend, an 81-year-old actress quietly following a 1950s booklet may be the most convincing argument for keeping workouts short, simple and sustainable.
She hasn’t reached the highest level. She doesn’t post workout selfies. She doesn’t claim the routine changed her life overnight.
She just does it. Every day. For 12 minutes.
And that, more than any cutting-edge training protocol, might be the real fitness secret worth copying.
