This week I was stretched. Not mentally. Physically. Assisted. I've decided I need a stretchologist in my life!! My new favourite type of -ologist 😀 Why? Because I walked out feeling like someone had oiled my joints, lifted my posture, and given my nervous system a reset. You know that feeling when you stand up and your body says “ahh.” instead of “ugh”. That. I felt immediately younger! Most people think stretching is a nice extra. Something you do if you’re into yoga, or if you’re injured, or if you want to warm up before 'real' exercise, or if you feel guilty for sitting. And they either stretch so gently nothing changes. Or they force it so hard their nervous system clamps down and makes them tighter. I've done both. Here’s what’s true. Stretching is a biological conversation between muscle fibres, connective tissue, and your nervous system. Your body is reading the tension you put into it and deciding whether to remodel or to protect. Stretching isn’t about being bendy. It’s about being able. Able to move well. Able to stay strong. Able to keep joints youthful, and tissues resilient, as the years stack up. Let's dive in...
Where insight becomes impact
What I’ve been looking at this week…
First. What stretching actually is Stretching is taking a muscle and its connective tissue into a longer position, then staying there long enough for your nervous system to stop treating it like a threat. That’s why calm, controlled, consistent stretching works. Your brain has to approve the range.
Dynamic vs static Dynamic stretching is movement through range. Think leg swings and arm circles. Best before resistance training because it warms tissue and primes coordination. Static stretching is a held position, usually 30 to 60 seconds. Best done on it's own because it needs attention to build range over time. It's not the warm up act! A 2024 meta-analysis found regular stretching over at least 2 weeks increases range of motion. Consistency matters.
Why people ignore stretching Because it’s quiet. No sweat. No scoreboard. But stiffness has impact. It changes posture, pain, gait, breathing mechanics, speed, and the mental load of moving through your day.
Stretching, flexibility, mobility, agility, hypermobility Stretching is what you do. Flexibility is the passive range of movement you can access. Mobility is range + strength. Range you can control. Agility is mobility + fast direction change. That’s nervous system timing. Hypermobility is extra range. Which can be a problem if it comes with pain or instability.
And my favourite... PNF - proprioceptive neuromuscular facilitation: this is assisted stretching that blends a stretch with a short muscle contraction, then a deeper stretch. It’s one reason why my assisted stretch session feel so potent, combined with timed exhales for a release of tension and emotion.
What’s involved in stretching: the 3 Fs Fascia. This is the connective tissue web that wraps and separates muscles. It needs to glide. When it gets sticky, you feel restricted. Think cling film that’s dried out. Fibres. Tightness is often your nervous system applying the brakes to your muscle fibres. Ageing can change the nerve-to-muscle connection at the neuromuscular junction. That’s the tiny “handshake” where a nerve tells a muscle fibre to relax or contract. When it’s less efficient, you can feel more guarded. Feelings. Mental stress can measurably increase muscle tension even without physical load. That’s why stretching can feel like an emotional exhale- especially when coupled with breathing.
The plot twist. Your arteries get stiff too Here’s what’s intriguing. Stretching doesn’t just change muscles. Reviews and trials suggest regular stretching can reduce arterial stiffness and improve blood pressure markers. Including an 8-week study where stretching outperformed brisk walking for BP improvement in people with high-normal BP or stage 1 hypertension. So yes. You stretch muscle. And you may be stretching your vessels too. That’s a very different story to “can you touch your toes.” ( which I can't, yet, but my stretchologist is working on it with me!)
Track it to hack it.
What I’ve been monitoring this week…
So how do you track how effective your stretches are? You need 3 dials
D1. Distance. Measure your range Pick one benchmark and measure it. Example - how far down your shins can your fingers go or how much of the wall behind you can you see when you turn your neck. If you love precision, add an angle tool. A simple goniometer or inclinometer gives you real numbers you can improve. If you love simplicity, use photos in the same position, same angle, same lighting
D2. Duration. Time your holds For static stretches, hold one stretch for 50 seconds - long enough for the nervous system to soften, especially if you slow your breathing at the same time. Long exhale breathing while you hold the stretch. It’s the permission slip for deeper range.
D3. Dose. How intense to go Use a simple scale 0-10. This is what I use with clients.
0 to 4/10: pleasant, probably too light to change much
6-7/10: strong stretch, controlled, breathing steady - this is the growth zone
8 to 10/10: pain, breath-holding, face-grimacing. this is where people get injured or rebound tighter
One of the biggest mistakes people make is either babying the stretch, or bullying the stretch. Precision beats punishment. Aim for 6 to 7 out of 10.
From knowing to doing.
What this means for YOU…
The 5-50 Flexibility Fix I’m making this simple this week. 5 stretches a day. 50 seconds each. But you’re going to do it with my favourite upgrade. The “soft face, slow breath, small range” rule.
First 10 seconds - arrive
Next 30 seconds - find a 6 out of 10 edge, keep the breath smooth
Final 10 seconds - add a gentle contraction of the stretched muscle, then relax and go a touch deeper
That’s a bite sized PNF style approach. It teaches control, not collapse.
The questions I get asked most about stretching Should I stretch every day. Yes. Small daily doses beat big sporadic sessions. Before or after cardio or resitance exercise. Dynamic before. Longer static holds after, or separate session. Why am I still tight even though I stretch. Because your nervous system doesn’t trust the range yet. Add control at end range, not just pulling. Does stretching prevent injury. The evidence is mixed. Stretching has mobility benefits, but it’s not a guaranteed injury shield.

And here's the most important part: Stretching is the tool. If you’re feeling stiff, less flexible, losing range, or getting cramps, it’s rarely just a stretching problem. You need to know what’s driving your stiffness in the first place.
This is where you go from guessing to testing.
There are 3 important panels to look at
Vascular: BP, lipids, ApoB, hs-CRP - because arteries stiffen too.
Metabolic: glucose, insulin, HbA1c, triglycerides, uric acid - because sugar stiffens collagen over time.
Mineral and hormones: vitamin D, magnesium, calcium, PTH, cortisol, oestrogen, testosterone - because you can’t relax what you can’t regulate.
Test. Don’t Guess.
💼 Case in point: A patient of mine, late-40s founder, trained three times a week, “stretched when he remembered,” and still felt stiff getting out of the car, plus calf cramps at night. We started with the 5-50. Within 10 days he said, “My hips feel freer and my sleep is calmer.” but the cramps and that deep rigid feeling kept showing up. So we stopped guessing and tested. His metabolic markers were quietly drifting. HbA1c and fasting insulin were higher than he expected, and his mineral flow showed low vitamin D with suboptimal magnesium levels. Once we corrected the drivers and kept the 5-50 going, the cramps settled, his morning stiffness dropped, and his stretching finally started to hold. That’s the point. Stretching is the tool. Biology decides how well it works.

Where you’ll find me…
Last week: I bounced my way through consultations and collaborations after that assisted stretch session! Also quite literally as my new chair is now a bouncy ball!
This week: I'm speaking to a room of CEOs and MDs on biohacking biology for business brilliance
Next week: It's Christmas! I’m heading to Hampshire with the children and the dogs for a few days of drift. Proper drift. Phone-free, slower mornings, longer walks, with time to reflect and reset.
A thought to pause on…
"Stretching is the art of lengthening. Lengthening your tissues, lengthening your breath, lengthening your life."
