80 REASONS WHY PLANNING BEATS LUCK
=================================
Whatever your level is be that beginner, developing athlete, elite performer, peaking at the exact moment you desire is never luck. It’s never just about “the big stage magic” & It’s never just “adrenaline.”
▶️ It’s architecture.
▶️ It’s deliberate.
▶️ It’s engineered.
Xu Jiajie’s 80.08m today in winning the Chinese National Championships isn’t just a distance. It’s a case study in what true performance planning looks like (albeit from distance).
After a year of setbacks, injuries, and dips in confidence, he didn’t chase any miracles (especially with such a big year in China next year with the Asian Championships & World Championships both being in China. He didn’t try to rebuild everything at once. He focused on the lowest hanging fruit which through discussion were the pieces that could move the needle fastest. The controllables that mattered most in the time available.
That’s what peaking really is:
➡️ Identifying the right problems
➡️ Solving the ones that matter
➡️ Stacking small wins until momentum returns
➡️ Creating the conditions for your stars to align
Peak performance isn’t about being perfect all year. It’s about being right when it matters.
Today, he was prepared.
Today, he felt ready
Today, he became national champion again.
And that’s the lesson for every athlete:
Your best throw, jump, lift, or race doesn’t happen by accident. It happens because you build the pathway to it, piece by piece, day by day.
Proud of him. Inspired by the journey.
This is what Performance looks like.

EFFICIENCY IS 👑
==============
If you’re going to build a system that is rooted in sound biomechanical principles, your performance model has to be just as real, just as robust, and just as mechanically sound.
Elite Javelin throwers have a superpower.
They can strategically “break” technique in certain areas so their body can self‑organise and unleash what truly matters, which is maximal, efficient force.
That doesn’t mean throw with ‘bad’ technique, but it does mean there is some flexibility around your throwing mechanics so you can take full advantage of the athletes’ superpower.
That being said, if you’re building a system for javelin from the ground up, then it makes sense to build it based on sound biomechanical principles so you can influence future generations of thrower in your system/ country!
So it’s not just about technique. It’s about performance and optimising what it takes to throw far!
More great throwing from World Junior Record holder, Yan Ziyi of Zhejiang Province, China. Having recently turned 18 years old, she will still be an u20 in 2027.
How far can she throw before she officially enters the senior ranks and how long until she breaks the World Record currently held by Barbora Spotskova of Czechia?
Surely it’s just a matter of time?
With only 2 years until the 2028 Games in LA, is there likely to be a bigger favourite for gold in the sport of athletics?

UNDERSTANDING ≠ EX*****ON
=========================
Constraints‑based learning in Javelin isn’t necessarily about forcing athletes into a singular technical template. Moreover it’s about reverse‑engineering performance. Start with the outcome in mind, understand the individual, and build a performance model.
Every thrower is chasing the same critical determinants of performance, but the pathway to optimising the ability to improve through the development of our mechanical KPIs is deeply personal.
—-—-—
▶️ Muscle morphology
▶️ Muscle architecture
▶️ Muscle fibre‑type distribution
▶️ Tendon compliance
▶️ Limb length
▶️ Segmental proportions
▶️ Neuromuscular coordination
▶️ Motor learning history
▶️ Injury profile
▶️ Training age
All of these shape how an athlete can best organise movement under pressure.
When we truly understand the athlete in front of us, we can stop coaching “technique” and start coaching performance expression.
We prepare them physically to execute the mechanical KPIs in a way that aligns with their biology, their structure, and their unique constraints.
That’s the real art and science of Performance Coaching in Javelin Throwing.

This one dives a little deeper into how constraints shape the throw and why your performance model matters more than any technical model ever will.

IT’S NEVER THE FAULT OF THE JAVELIN
==============================
Back Foot Contact (BFC) isn’t just a landing, but it’s a super KPI. In Javelin Throwing, BFC is one of the most debated KPIs we have. Everyone has a version of “right”. But the truth is more nuanced: There are many ways to make BFC work, but only a few ways to make it optimal. And one of the biggest differentiators?
How the left leg advances at BFC.
We know from the research that the time from BFC to FFC has a strong correlation with release velocity. Essentially that window is where the system can mitigate deceleration or energy can completely dissipate.
The advancement of the front leg at BFC influences:
- Pelvis rotation timing
- COM interaction
- Deceleration load
- Run‑off efficiency
- The athlete’s ability to organise themselves before FFC
And this is where individuality matters.
- Anthropometry (limb lengths, segment ratios)
- Muscle architecture (CSA, pennation, elastic vs contractile bias)
- Gender differences (pelvic structure, Q‑angle)
- Evolutionary traits (regional morphology, genetic nuance)
- Physiology (fascia‑driven vs muscle‑driven movers)
All of these shape how an athlete can and should land at BFC.
But regardless of profile, two principles hold true:
1️⃣ Choose a landing that allows the pelvis to rotate towards the direction of the throw prior to FFC.
NOTE: The best throwers achieve this consistently.
2️⃣ Choose a landing that minimises system deceleration so the athlete gets from BFC to FFC as efficiently as possible.
If the pre‑run‑off action isn’t correct…
If the run‑off contact isn’t short and orientated…
If the left leg isn’t advancing in a way that supports rotation and timing…
Then even a “good” BFC won’t necessarily enable an athlete to progress optimally.
This is very nuanced but it’s the nuance I’m want to bring back into the conversation around our discipline.

WHAT’S IT REALLY ALL ABOUT?
========================
There’s a point in every journey where you stop looking outward for answers and start looking inward for clarity. A point where you realise that the environments you’ve lived in, the people you’ve met, and the challenges you’ve faced haven’t just shaped you…they’ve forged you.
We all come from somewhere. And each of us carries a perspective that no one else on this planet can replicate. That perspective is earned through experience, adversity, curiosity, and the courage to keep moving forward when standing still would be easier.
Over the past few years, I’ve learned the value of slowing down long enough to reflect. Not to fill time with noise, but to understand the patterns, lessons, and truths that have shaped who I am today. Reflection isn’t passive; it’s an active part of growth. It’s where clarity lives.
In simple terms:
I know my passion. I know my purpose. And I know that whatever has happened, or will happen that I’m as driven as ever. My work isn’t just a job; it’s opportunity…a calling! But now, I understand balance. I understand what matters. And nothing will ever compromise that.
Life isn’t about trying to be everything. It’s about being exceptional at the things that already make you you. If others can’t see that value, that’s often a reflection of their own unfulfilled potential, not yours.
Whatever happens next, choose happiness. Choose purpose. Choose the path that aligns with who you are and not who others expect you to be. There’s more than enough in this world for all of us to thrive.
Onwards. With clarity. With purpose. With balance. 🙌🏼
It’s been a while.
The last few years have been a period of change, reflection, and growth — moving from seven years as a full‑time javelin coach in China to leading coaching performance & pathways in track and field with the SOTC.
Stepping back from Instagram wasn’t accidental. The noise around our event has grown, and not always in the right direction. Misinformation spreads fast. Quality doesn’t.But I’ve always believed in sharing valuable, evidence‑based, experience‑driven information. I benefitted from that as a young athlete and coach — and I know the next generation needs it more than ever.
A recent trip to Hong Kong reminded me of my core values as a coach: clarity, honesty, technical excellence, and a commitment to raising standards.
So this is me getting back on the horse.
I’ve launched my new website (updates coming quickly), opened up opportunities to work with throwers internationally — both in‑person and remotely — and I’m delivering workshops and presenting at conferences around the world.
At heart, I’m still what I’ve always been:
A professional javelin coach dedicated to high‑performance, skill mastery, and developing world‑class throwers.
This clip is a reminder of why mechanics matter — and why our event deserves better information.
Let’s raise the standard again.
If you’re serious about performance, stay tuned. More coming.

💭 Great minds don’t just produce results & throw far. They collaborate and think together! 🧑🎓
🤝 When athletes & coaches come together to share ideas, something exciting, powerful and sustainable happens. 🔥
💡 We all have unique perspectives on our sport, fostered by our upbringing and the environments we’re grown in and experienced. That uniqueness almost always creates insight that through open and honest discussion, can fill gaps in the knowledge of others, but also yield better solutions to some of the challenges we encounter. No one alone has all of the answers. 🙋🏻♂️
❓ Getting together is about more than just training or box ticking. it’s about building a community where every insight, every question, and every breakthrough lifts everyone higher and adds to the subsequent sense of achievement.
➡️ For Javelin throwers (and athletes in general), these connections can mean everything. They can form lifelong bonds through the shared experiences of all. The exchange of technical knowledge, mindset & mentality, and experiences through life and sport, can accelerate growth in ways solo practice rarely does.
➡️ I’ve always believed in fostering these conversations and cooperations — your next personal best might come from a shared piece of wisdom that unlocked something within you.
As always, we grow stronger, together. 🎯
➡️ Interested in attending a training camp with elite athletes and coaches who don’t just instruct, but fully understand what it takes to throw far and provide the appropriate feedback through effective coaching and training programme prescriptions, then drop me a message. We have plans to continue to grow and would be delighted to help as many driven and committed athletes as we can accommodate with additional skills, tools and thought processes to facilitate that journey!

BETTER TOGETHER
===============
We had our last throwing session this morning before the Men’s Javelin final at the 15th Chinese National Games takes place on 18th November, at 9.35am.
Provincial Athletics in China is traditionally parochial in nature, however the future for Athletics in China, is greater collaboration between provinces, coaches and teams to foster culture, togetherness and competition to drive standards.
I grew up in a generation where it was more satisfying to beat your friends, than it was your adversaries. Bragging rights around the coffee table or over a beer with your contemporaries, reminiscing about what’s just been or past experiences is a huge part of the journey and should be embraced.
China has come a long way, but there are many miles still to travel.
————————
It’s been a real pleasure welcoming the Tianjin team to our home in Shanghai for the last week or so. Our home is their home!
We’re stronger together. 💪🏼
Sport is, or should be, a microcosm of life! And we should constantly strive for that Utopia that we seek 🙌🏼
