Fi Modderman - Fitness & Health Coach

Fi Modderman - Fitness & Health Coach I help you develop a healthy relationship to food, fitness and your body, so that you can just get on with enjoying the life you are here for! Wrong! You can.

I help women switch the internal narrative when it comes to their health and body, from "I can't," to "I can." It's from the inside that the real transformation happens. If you don't truly BELIEVE that you can have the body and health and energy you desire - then you won't. You won't stay consistent with the behaviour and lifestyle changes that need to happen externally - because hey, you believe

deep down that you can't actually do it right! But we need to start not only with the 'outside world', but most importantly, your 'inside world'. What is going on in your head? So alongside the 'what to do' in terms of eating, exercise, stress and sleep, let's change all those life-long stories, patterns, routines and ways of being that you're currently accidentally stuck in. If you don't know those programs are running in the background keeping you stuck, how can you change them? That's why working alongside a coach, who's job it is to shine a light on those pesky stories that tell you you "can't", is what will ultimately have you doing what it takes to get you to where you want to be long term. But you MUST be ready and willing to do the work! Not just the work of loading up your plate with chicken and broccoli (blah really? No, we don't have to do that either!), but the work of catching reoccurring thoughts, beliefs and stories that no longer serve you - and rewire in the new ones that do! You can do this. I believe in you. And I'm here to help. Just message me to get started with coaching now. xx Fi

I discovered at 14, how running saved my brain and emotional health - and I firmly believe it has saved my life.

It allows me to process emotion, clear my head, flip a terrible mood into a tolerable mood - and leaves me with a physical buzz in my body that no other exercise can induce.

Now that I'm 44, science in women's physiology is finally getting there, which I'm very grateful for and happy about! But one narrative that is now doing the rounds, is that women need to peel riiiiiiight back on going for runs.

Because you know... cortisol, belly fat, worsened sleep... "If you want to reach your goal body - you need to stop running."

And, when I hear it coming from other trainers in the fitness industry, telling this to their clients - it really disappoints me even more (like I have seen on my algorithm this past week).

I've been in the fitness industry from the age of 18 and yes, if ALL you were doing in your midlife years was running, I'd probably advise you to add in strength training and make sure you're eating enough to support your muscle and bone.

However, being told you should only lift heavy and cut the running back or stop it altogether? Nah.

Yes, the cardio benefits are solid: lung health, heart health, blood pressure etc.

But more importantly, if running is something you love, gets you outside, in nature (maybe), connecting with fellow runners, turns a chaotic brain (hello fellow adhd-ers??) into a calm brain, has you actually doing some exercise instead of no exercise - then keep.effing.running.

Thank you for coming to my Ted-Talk. 😜

What a way to celebrate getting to be another year older!!

After fearing the ageing process in those first few decades, I have well and truly come to terms with being in my forties!

And have reframed each birthday as feeling privileged to BE another year older.
Privileged to AGE at all!

So to celebrate the year - and for the novelty of 'how old is too old?' these are my 'party tricks' to give a go!

Anyone keen to join me on this experiment with your own birthday antics!?

Honestly, I just can NOT with the socks that I cover the ankles! 😅

Today I wore socks that have been in my drawer for approximately 5.87 years without being worn.

And when I put those bad boys on my feet this morning before heading out for a run, watching them slide up over my ankles, I effing steeled myself...

'It doesn't matter Fiona... It'll be fine. They are comfortable enough. Just go for your run...'

2.4km later, with every step my brain focusing on my suffocating ankles, I just had to stop and roll down those socks!

Because eff being uncomfortable when those ankles need to BREATHE, least you feel positively claustrophobic....

Please tell me I'm not the only 43 year old who can't cope with her ankles being covered during exercise!? 😩😅😆

I became obsessed with losing weight, getting smaller, in an attempt to 'look good' from my mid-teens.

Magazines led the charge in my era (Hello the 90's!), with covers berating the celebrities who dared to show their cellulite at the beach, articles written about their body transformations, air-brushing being a thing we all knew... but still compared ourselves to!

All I wanted, was to be the value I had learned society had expected of me - to look a certain way.

It was an obsession that eventually led to a full-blown eating disorder at age 22.

I TRIED SO HARD to not want to eat ALL the food (because you know, back then the only nutrition advice was just to 'eat less'!), but that just led my brain to rebel and eat even MORE!!

So I attempted to run it off. A 30 minute run wasn't good enough, so it became 45 minutes, then 60 minutes and eventually running for 90 minutes most days!

And still, all this training... it didn't work to be smaller.

*Sigh*

If 'only' I'd known what I know now, right!?

20+ years later, at 43, I just train to be able to keep doing all the cool s**t I love to be able to do - like climb hills and stuff!

I have long-since learned to eat in a way that gives me sustained energy all day, that makes me feel mentally stable and that grows my precious muscle - which I'm going to need all of the above in order to age well.

Because now, I value being able to lead a long and active life FAR more than a life where I obsess over how I look... And I can't tell you the emotional peace this has given me.

I've been waking up at 5am, from as early as a teenager.

These days, as a 43 year year old Mum, I CHOOSE to set my alarm for 4am every day (even on the weekends).

And I effing LOVE it!

House to myself.
Chilling before everyone and everything needs me.
Some days I get lots of work done.
Or washing in the machine started and dishwasher empty.
Other days I save items to my Temu cart that I'll never actually buy.
All whilst simultaneously half-watching, half-listening to some BS reality tv show.

The cats go nuts around the room, my exercise has been ticked off for the day and I 100% relate the notion that I'm a 'sunrise wa**er' who adores the changing sky colours as everyone else sleep. 🤣

Most people think I'm nuts!

But I've course I'm not alone in this.... let me know if you can relate!

The scale has been running your life for long enough.

You step on.
Number's up.
Your whole day shifts... questioning what you ate, whether to skip breakfast, if any of this is even working.
Not to mention making yourself feel like a useless bag of...!

That's not exactly what I would call 'health.'

The scale measures one thing - gravitational pull. That's it.
It's not measuring your strength, your energy, your physical capability, or your worth.

It doesn't tell you if you're making 'progress'. Because shouldn't progress be about all of the above?
How you feel in your body?
If you go through the day with a bounce in your step, if you can lift up your child/grandchild with relative ease, if you are the happiest version of yourself for not only you, but the ones you love around you?

So swipe through for 5 ways to stop letting a number decide how you feel about yourself...

For the past 5 years or so, many women I know have been diagnosed. 
I've listened to them tell their stories, wondered a little bit if I had it too when I related to some of their behaviours, but then dismissed the notion because I couldn't relate to absolutely everything they said. 

But with more conversations this year, some instagram posts and finally meeting a new PT client who works all day, every day with helping neurodiverse people (she said to me, "If you don't have ADHD I don't know how to do my job"), then I decided to seek a formal diagnosis

And now I know so many of my whys.....

It.all.makes.sense...

Why I could never follow a meal plan or diet plan. 
Why I would immediately want to rebel if I told myself I had to cut out foods or had to stick to something. 
Why I need accountability to show up for exercise. 
Why I need to move my body daily to 'be a nicer human'. 
Why I have used alcohol as a coping tool. 
Why I use food as a coping tool. 
Why I was always conscious of my body image and how I presented to the world.
Why I overshare at random moments, or blurt weird s**t out. Lol. 
Why I never feel content with the way life is and am always looking for the next thing. 
Why I have worked so hard to understand how mindset, thoughts, feelings and beliefs affect our behaviours and therefore our 'results' in life and health. Then actively have worked on my own mindset to get to where I am now with my lifestyle choices.
Why I live in a constant state of urgency and overwhelm. 
Why I never feel I can relax (even if my body is sitting, my brain is telling me I need to get up and be productive and do something useful). 
Why I constantly worry everyone doesn't like me, or that I've done something wrong or that I've failed people.
Why my emotions can go from zero to 100 in seconds.
Why I have built structures, routines and systems into my life.
Why I have a battle with myself every night to go and brush my teeth and go to bed.
Why I have procrastinated my entire life, in every aspect of my life.

Why I literally can not sit still.

And so much more!

Watch this space, as I am joining the dots on WHY so many women may be stru

Everyone sees the strong body at 43.

The consistency. The discipline.
25 years in the fitness industry... It LOOKS I've got my sh*t together when it comes to health.

And I kinda do.
I have a strong, capable body that allows me to do whatever physical thing I need from it!

But here's what you don't see.

Every Sunday morning is the only day I have time for a run. I get up. Have my coffee. Do some work on the computer. By then, the sun's up. Everyone's still asleep. It's quiet. It's perfect.

I open the door.

And it's f*cking freezing!

And I absolutely do NOT want to go!

I don't want the cold. I don't want to find my activewear or lace up my shoes or scroll through Spotify looking for something to run to. It all feels like too much. I'd rather stay cosy inside, chilling in the quiet of the morning.

So I close the door. I sit back down. And the voice starts.

"Too cold. Too tired. Just stay in. You've earned the rest."

And it can take me an hour. Sometimes two.

My body gets restless. That internal voice won't let up...

Until I go.

I have to remind myself every blimmin' time: You KNOW you feel SO GOOD when you're finished - so just bloody do it already!
That's what eventually gets me out the door. Not motivation!
Just the memory of how good it feels on the other side - and the willingness to sit there arguing with my own brain until that memory wins.

25 years in as a trainer. 30 years as 'someone who runs'. The body you see. The results. The strength. And the damn voice still tries to talk me out of it every.single.workout. (It's not only runs that this is the case for!! 😩😅)

The voice talking you out of exercise doesn't go away just because you get fitter or more experienced.
You just get better at not listening... Because you know that voice ain't right!!

Nobody tells you that bit. And that's actually the most important part of exercising consistently!

Because if you're waiting for the day it gets easy - for the day you just WANT to do it - you'll be waiting forever.

The work is doing it ANYWAY.
Most days of the week. Not all. Just most.

💚

Tell me, how loud is YOUR internal voice trying to talk you out of exercise?

I've spent 20 years in the fitness industry watching women white-knuckle their way through plans they bought in a moment they were feeling low, that were promising that THIS was going to be the way out of their body-image pain once and for all... that were never actually designed for them...

Someone else's 5am wake-up.
Someone else's meal prep system.
Someone else's workout split.
And when it falls apart (because 98% of the time it usually does) they end up blaming themselves for not having enough discipline. For being too useless/lazy/(insert negative word here) to follow through.

But here's what I've learned from working with hundreds of women in my career: the plan isn't the problem. The FIT is.

As you read through this carousel, you'll see exactly how I personally do health. By most conventional standards, a fitness coach doing half of these things means I'm not doing things 'right'.

But my energy is always stable, all day.
I can lift heavy s**t, which means the everyday lifting of stuff feels easy for me.
I feel better than I did a decade ago.
And maybe most importantly, I've been consistent for YEARS - because I stopped trying to squeeze myself into someone else's version of healthy and started building something that actually works for MY life.

So let that be your goal.
Forget perfection.
Forget the "optimal" protocol.
Create your own habits - something sustainable enough that you keep showing up for it... for years.

Take guidance where you need it. Learn the principles. And then make it YOURS.

What's one "rule" you've quietly ditched that's actually made things easier? Tell me below 👇

Raise your hand if you want to get strong… but also the gym is a hard no. 🙋‍♀️

Same. I'm exactly the same!
Even though I've been in the fitness industry for 25 years - gyms are not for me.
...Waiting for machines....Too many people around....Other human's sweat....Comparison syndrome....WTF am I supposed to DO!?

But I DO think society believes that if you aren't working out in a gym, then you aren't REALLY training. That home workouts are just a bit of a warmup for the real thing...

Which is a total pet peeve of mine!

Because every day, I work with women aged 40-80, who are either in their homes, or mine - building REAL strength.

The kind where you notice it while carrying your shopping, climbing staircases/hills, being able to balance on one leg again to put your un**es on (without having to sit down), blow-drying your hair in one go because your arms aren't tiring.
Just doing your daily things - but with more ease!

The type of resistance workouts I write for myself and my clients, are still challenging!

Even if we don't have the big gym equipment! They can all be done with some simple sets of dumbbells, a kettlebell, a b***y band, a yoga block, and a trusty dining-room chair!

That's genuinely it.

So if the gym has been sitting in the back of your head as the thing you'll do "when you're ready"… you're already ready. You just don't need the gym part.

Let me know in the comments, has the idea that you NEED a gym been stopping you from starting strength training?
