I became a lawyer because I thought it was my calling. By 15, I was convinced it was my future. I spent 8 years in law, even built my own firm.

But the reality? It wasn’t what I expected.

The system was broken. Mentorship was non-existent. The industry was male-dominated. And no matter how hard I tried, I never truly fit.

Walking away wasn’t easy. It felt like failure. But it wasn’t.

Because in truth, my passion had always been elsewhere.

I grew up with challenge after challenge:

↳ Knock-kneed and major surgery at 6 (I had to relearn how to walk)
↳ Scoliosis with chronic back pain
↳ Severe IBS and acid reflux
↳ Wrist arthritis that led to a partial fusion and bone graft

Those setbacks forced me to explore the power of health, strength, and resilience. Over time, it became clear: fitness wasn’t just something I loved. It was my purpose.

Today, I coach men and women in their 30s and 40s who feel stuck. The pants are tighter. The belly’s bigger. Energy is lower. Strength feels like a thing of the past.

I know that story—because I’ve lived it.

And I also know this: you don’t need perfection, endless diets, or 2-hour gym sessions. You need a simple, structured approach to get strong again. To build the energy, resilience, and confidence that carries into your 40s, 50s, and beyond.

That’s what I do.

If you’re ready to get stronger, fitter and leaner than you ever thought possible, and make your 40s your best decade yet—let’s connect.

Online Fitness Coach | I help busy professionals lose weight and improve mental strength so that they can perform at the highest level

My fitness journey stemmed from a dark place.
 
I was stuck in the depths of depression and anxiety. I didn’t love the person I was - on the inside or outside.
 
The gym was my outlet. But my first few years were full of trial and error and I made my fair share of mistakes.
 
Eventually things started to click. I began diving deep into how the mind and body work, educating myself and shifting emphasis to balance, mindset, and sustainable habits.  This journey has truly given me my life back. And now I have found my passion in helping others do the same.
 
My goal is to help you build a strong body and mind, through lifestyle changes that will last forever.

It's way more than just a physical transformation, I'm not joking when I say it affects every single area of your life. Performance at work, energy and mental clarity, how you show up as a leader, spouse, parent, and everything in between.
 
Maybe you are in the place I previously was, or you just want to pursue the best version of yourself.
 
Either way, I'd love to support you in your journey to health, healing, and lifelong habits.

I don’t train to be a bodybuilder.
I don’t train to be super shredded.

I train so my body doesn’t limit my life.

I train for my mental health and my physical health.

So I can wake up with energy.
So I can handle stress better.
So I can move through my day without aches, pain, or exhaustion running the show.

I train so I can say yes more often.

Yes to trips.
Yes to experiences.
Yes to moving, playing, and being active without overthinking it.
Yes to long days without feeling completely drained.

Most of the people I work with aren’t chasing extremes.

They’re busy. They have families, careers, responsibilities, and full lives they actually like.

They just don’t want their body to be the thing that holds them back.

They want the energy to keep up with their kids.

To travel without worrying about how they’ll feel.
To play sports again.
To move without pain.
To get through long days without being exhausted and checked out.

I want to enjoy the life I’m building, not feel restricted by my body while I’m living it.

That’s what fitness is actually for.

...

After working with hundreds of clients to lose fat, build muscle, and create a sustainable healthy lifestyle over the past 5 years, our process is pretty much guaranteed and it’s so damn simple.

For February, we want to help 4 people who want to break the all-or-nothing cycle, feel confident in their body, and boost their energy

Comment “RESULTS” and we can have a conversation to find out if you qualify.

Most of my life, I hated every second of being alive.

Because of that, birthdays were never something I looked forward to. 

They just felt like a reminder of another year of a miserable existence.

Even after transforming my life, I still never liked celebrating my birthday. There was always a negative cloud around it.

Plus I never felt worthy or deserving of it, so I avoided it.

This year has me emotional though, cause it’s the first year it’s different.

This is the first year I actually wanted to plan something. I have people in my life and I want to be around them. I want to celebrate.

It feels a bit uncomfortable and new... but damn does it feel good.

I feel beyond blessed to be here and see another year.

Before you say you're depressed, be honest.

You:

• don’t exercise
• barely move
• live indoors
• eat ultra-processed food
• sleep like shit
• avoid anything that gives your life meaning

That’s not a chemical imbalance.

That’s a lifestyle built to feel awful.

I’ve lived this. Many of my clients have too.

When movement disappears, sleep is inconsistent, food lacks nourishment, and life becomes all obligation with no outlet, your mental health takes the hit first.

This doesn’t mean therapy or medication don’t have a place. They absolutely do for many people.

But you can’t out-medicate a life that’s built against your biology.

Start with the basics:

• move daily
• get sunlight 
• eat real food 
• sleep consistently 
• do something that makes you feel alive again

Mental health isn’t just about what’s happening in your head.

It’s deeply tied to how you live.

Pro tip: stop wearing running shoes when you lift.

You need a flat, stable surface under your feet.

Not a cushioned, squishy base that absorbs force.

Running shoes are built to absorb impact.

Lifting requires stability and force transfer.

That’s why going barefoot or wearing barefoot-style shoes are elite.
(At the very least, wear flat shoes like Vans or Converse.)

A stable base improves:

• balance
• stability
• force production
• muscle engagement
• overall movement quality

This matters on every single movement, but especially on your big lifts: squats, deadlifts, presses, hinges.

Your feet are your foundation.

Get that wrong, and everything above it has to compensate.

Small change. Big difference.

My clients have lost over 6,000 lbs combined.

Here’s what actually works... and what doesn’t.

1. Dieting less, not more.

Most came in under-eating, stressed, and exhausted. Another “6-week shred” would’ve made things worse. We rebuild metabolism first so fat loss fits real life.

2. Eating out without guilt.

Busy people don’t fail because they eat out. They fail because one meal turns into “might as well write the day off.” 

My clients learn how to eat out, travel, and still make progress.

Use my Healthy Fast Food Cheat Sheet here: https://lnkd.in/eRHkcGYd

3. No all-or-nothing thinking. 

Skipped workout, late meeting, or imperfect meal? They don’t panic or “start over Monday.” They return to baseline habits at the next opportunity.

4. Training for life, not calorie burn. 

We train for strength, energy, confidence, resilience, and mobility — so people can live without limitations, not burn out chasing aesthetics.

5. Systems > motivation. 

High performers need structure that fits their schedule, simple nutrition rules, default workouts, and clarity when life gets chaotic.

6. Accountability beats willpower.

Nobody thrives alone under stress. Guidance and support are what turn short-term fat loss into a lifestyle.

7. Consistency over intensity.

No extremes. No crash diets. No burnout. Just habits that work for real people with real responsibilities.

6,000+ lbs lost.

But more importantly: energy is back, confidence is higher, health is restored, and people can keep up with their kids, travel, and actually enjoy life again.

You can build a successful career and still destroy your health in the process.

I see it every day.

Hell, I lived it for a while too. It’s easy to sacrifice sleep, live in a constant state of stress, and put others or the business ahead of yourself.

High performers will often skip workouts for meetings, live on caffeine, sleep five hours, stress-eat at night, and ignore the warning signs.

Then they wonder why they feel heavy, exhausted, unfocused, and stuck in the same on-off cycle.

My client David came to me like this.

His career was demanding, and he was traveling constantly.

He was doing well professionally, but his health was slowly slipping. Energy was low, weight was creeping up, sleep was off, and everything felt harder than it should have.

He was running his body the same way most people run their health — last on the list.

Your body isn’t a machine you can run into the ground and expect peak performance from.

It needs movement.
Quality food.
Sleep.
Structure.
Boundaries.

Once we stopped treating his health like something to squeeze in and started treating it like a non-negotiable, everything changed.

He got leaner, stronger, had more energy, and was able to handle work and travel without falling apart every time life got busy.

You wouldn’t run your business the way you run your health.

Stop treating your body like a liability.

It’s actually your biggest asset.

If this feels familiar and you want to talk through what a sustainable approach could look like for your life, comment “HEALTH” or send me a DM.

If you feel old or weak, that’s exactly why you should work out.

If your energy is low, that’s exactly why you should work out.

If work and family take everything out of you, that’s exactly why you should work out.

Waiting until you feel better, less busy, or more motivated is how the cycle continues.

Movement isn’t something you earn once life calms down.

It’s the thing that creates more energy, resilience, and capacity for life.

You don’t break the cycle by thinking about it.
You break it by taking action.

Not when it’s convenient.

But because your life demands more from you now.

There is absolutely nothing special about me.

But there is a reason why why I’ve stayed consistent for 12+ years when most people quit.

Before you say you're depressed, be honest with yourself.

This is THE elite exercise for hip mobility:

(Especially if you sit at a desk all day)

It’s called 90/90

It’s my all time favorite mobility drill for internal and external rotation of the hip

Sit on the ground with both legs at 90°
(This alone may already be a good stretch for you)

Then begin to lean forward to deepen the stretch

Key here is actively pressing your front knee and ankle into the ground while simultaneously raising your back ankle off the ground

Hold in that active stretch for a slow 5 seconds then release

That is one rep

Repeat 5-10 reps each side 

...

P.S. I'm Mackenzie → I've helped 200+ busy professionals lose 20-50 lbs without giving up their social life or working out 2+ hours a day.

Follow for daily tips that actually work in the real world (not just in theory)

An underrated way to stop snacking all the time has nothing to do with food.

Have fulfilling hobbies.
Do meaningful work.
Live a fuller life.

Most overeating isn’t about hunger.

It’s boredom, disconnection, stress, and having too much mental space and nothing that actually fills it.

When your day feels empty or draining, food becomes the easiest source of comfort, stimulation, or relief.

Of course you’re thinking about snacks.

But when you’re engaged, challenged, connected, and doing things that give you purpose, the constant urge to eat just to eat fades into the background.

Food stops being entertainment.

Build a life you’re excited about, and your relationship with food changes without forcing it.

Most people don't want to hear it, but it's true.

“I don’t have time to exercise.”

Ok, pull up your screen time real quick and tell me that again...

For most people, time isn’t actually the issue. 

Yeah - life is busy, work is demanding schedules are unpredictable. Kids, travel, stress, responsibilities. 

By the end of the day, there’s nothing left.

The problem isn’t a lack of effort. It’s that exercise isn’t built into life in a way that survives real life.

When workouts require perfect conditions, long sessions, or high motivation, they’re the first thing to go. 

And then people blame themselves for being “inconsistent.”

The fix isn’t finding more time.
It’s simplifying the plan.

- shorter, efficient workouts
- daily movement that fits into the day you already have 
- clear non-negotiables instead of all-or-nothing thinking

When exercise is structured into your routine instead of treated like an optional task, consistency stops being a fight.

This is exactly what my client David did.

He has two young kids, a demanding job, and travels every week for work. 

Time was his biggest concern coming in and he was stuck in the cycle of starting and falling off when life gets busy for years. 

We didn’t add more to his plate or ask him to overhaul his life.

We built structure around his reality.

Now he’s the leanest he’s ever been, hitting PRs in the gym, training consistently even while traveling, and no longer starting over every time life gets busy.

It’s the same life, but different structure, and completely different results.

Time usually isn’t the issue. The plan is.

...

I hear some heart wrenching things on my calls each week.

Parents who are bedridden and a burden on their family.

Grandparents who never met their grandkids.

Family members who can’t climb stairs or do yard work without being winded.

People getting wake-up calls with heart attacks, strokes, pre-diabetes, mobility declining — all saying the same thing:
“I thought I had more time.”

The big theme is: most people want to keep up with their kids, their family, and their life without limitations.

The goal isn't to get shredded or be jacked. 

It’s just to move, play, travel, stay present, and actually enjoy the life they’ve built.

Meanwhile, they built the businesses, hit the income goals, created stability for everyone else... but at what cost?

You can’t enjoy the fruits of your labor if you don’t have the health to enjoy it.

What’s the point of building a great life if you can’t participate in it?

Not being able to play with your kids, getting winded on stairs, avoiding travel because of low energy, saying no to experiences because your body can’t keep up.

These moments add up. 

And they pull you away from the very people and memories you were working so hard for.

Clients tell me things like:
“I don’t want to sit on the sidelines of my own life.”
“I don’t want my kids to remember me as tired.”
“I don’t want to end up like my parents.”

And that’s why most people finally change.

To climb stairs.
To travel.
To play.
To feel strong and capable again.

To LIVE life.

Success means nothing if your health can’t support it.

Your body is the vehicle for the next 40 years.

Stop worrying about the best way to start transforming your life.

Just fucking start.

Most people aren’t stuck because they don’t know what to do.

They’re stuck because they’re waiting for certainty before they move.

They want the plan to be perfect. They want to feel ready. They want life to calm down first.

But clarity doesn’t come before action. It comes after you start.

Life doesn’t get less busy. Responsibilities don’t magically disappear. If you wait for the right time, you’ll stay exactly where you are.

Progress starts when you choose one small, unglamorous action and commit to it anyway.

Walking consistently. Eating with a little more intention. Going to bed earlier even when it’s inconvenient.

You don’t need the full path mapped out.

You just need to stop negotiating with yourself and take the first step.

Momentum is built, not found.

Health isn’t just about how long you live.

It’s about how present you are while you’re here.

I’ve had seasons where I was technically “doing all the right things” but still felt exhausted, anxious, checked out, and constantly behind. 

I was going through the motions. Always thinking about what was next instead of actually being where I was.

And that’s when it hit me. What’s the point of building a great life if you don’t have the energy to truly LIVE it?

Health isn’t just about preventing disease or adding years down the road. 

It’s about having the capacity to show up right now. 

To have energy at the end of the day. 
To be patient with the people you love. 
To be present instead of mentally somewhere else.

I see this all the time with the people I work with. 

They’re successful, driven, and responsible. They’ve built careers, families, and full lives. But they’re beaten down. 

Their health slowly becomes the thing they sacrifice to keep everything else running.

And over time, that cost adds up.

The goal is being able to keep up with your kids, your work, your relationships, and your life without feeling limited by your body or your energy.

That’s the version of health I care about. 
And that’s the one I try to live by now.

Because being here matters. 

But being present is everything.

Most people don’t know why their progress has stalled.

This 5-minute Results Accelerator quiz will show you exactly what’s holding you back—whether it’s habits, stress, or metabolism.

Comment “RESULTS” and I’ll send it over.

Average mindset:

• waits for motivation
• avoids discomfort
• wants variety
• blames time

Elite mindset:

• builds structure
• takes ownership
• repeats the basics
• embraces boredom

When life is busy, unpredictable, and already full with work, kids, stress, travel, and responsibilities, relying on motivation or willpower is a losing game.

Structure removes decision fatigue. 

Ownership stops the “start over Monday” cycle. 

Repeating the basics makes progress automatic, even on chaotic weeks. 

And embracing boredom is what allows results to last instead of constantly resetting.

The people who get leaner, stronger, and more confident aren’t doing more. They’re doing less, but doing it consistently.

Build structure that holds when life gets busy.

Master the boring fundamentals.

Stop waiting for perfect weeks.

That’s how you close the gap and keep results long term.

Watch this if you don’t have time to exercise

An easy life is not a good life.

The real reward comes from hard work.

Pushing yourself to do more.

Grinding out another rep.

Executing on the project even when you’re tired and unsure.

I know that because every meaningful thing in my life came from choosing the harder path.

Overcoming trauma and depression.

Getting in the gym when my mental health was at its worst.

Working two jobs for years just to stay afloat.

Quitting a job that felt safe to bet on myself.

Forcing myself into uncomfortable situations to overcome social anxiety.

Moving across the country to start over on my own.

Setting boundaries that disappointed people but protected my peace.

Showing up to train, write, lead, and grow even when I didn’t feel ready or confident.

None of that felt good in the moment.

Quite the opposite. It was a grind, it was uncomfortable, scary, lonely at times.

There were setbacks, failures, and long stretches where I questioned everything.

But that’s where all the growth happened.

The work ethic, resilience and confidence that wasn’t handed to me, but earned.

The comfortable path would’ve kept me numb, stuck, and small.

The hard path forced me to become someone I’m proud of.

Hard work isn’t punishment.

Discomfort isn’t a sign you’re doing it wrong.

It’s the price of building a life that actually feels aligned, fulfilling, and yours.

Embrace the hard.

That’s where everything worthwhile lives.

Sleeping 7–8 hours isn’t optional if you want fat loss.

When sleep is off, everything else feels harder than it needs to be.

Poor sleep:
• increases hunger hormones
• lowers insulin sensitivity
• increases cravings
• slows recovery
• raises cortisol

That’s why fat loss feels like a constant fight instead of something that builds momentum.

Fix your sleep and suddenly food decisions are easier. Training feels better. Energy stabilizes. Cravings calm down. Progress stops feeling forced.

Most people try to out-train or out-diet bad sleep. It never works.

If fat loss has felt harder than it should, start here.

...

If you’ve ever felt like you’re doing “all the right things” but nothing is changing...
