Personal Training for Adults 50+

HOW CAN I HELP YOU?

Personal Training & Performance Coaching

A structured coaching experience for adults 50+ who want to improve their strength, movement, body composition and long-term physical performance.

There are three tiers or levels of support:

Foundation Package
Build the fundamentals.

CORE Performance Package
Train, move and perform better.

Elite Performance Package
Comprehensive training, nutrition and accountability.

TRAINING AFTER 50 SHOULDN'T MEAN LOWERING YOUR EXPECTATIONS.

As we get older, maintaining strength, muscle, movement quality and a healthy body composition becomes increasingly important. But that doesn't mean avoiding challenging training or settling for simply “staying active.”

The CORE Framework is built around improving what you can currently do and building from there

I combine progressive strength training with movement assessment, intentional exercise regression, nutrition and lifestyle coaching to build a programme around you.

Whether your goal is to become stronger, improve your posture, lose body fat, move without restriction or simply feel capable again, we establish where you are now and progressively build from there.

No generic programmes. No unnecessary punishment. No treating you like you're fragile.

I offer a money back guarantee for both my in-person and online services.

No results...your money back

Today, my work is about guiding others through their own transformation, not just changing their body, but rebuilding confidence, structure, and self-trust. I’ve helped over 30 individuals improve their body composition and completely reframe the way they approach training, nutrition, and themselves.

Top Client Wins:

Mark, 55 - “I feel younger.”

When Mark and I first started working together, the primary focus was getting him back into a more capable, sustainable position from a fitness standpoint. Our initial goal was simple: improve his endurance and cardiovascular fitness.

Fast forward a few months and Mark can now complete two full rounds of the Battlebox arena, roughly 25 minutes of non-stop exercise, including squats, push-ups, and full-body movements. When we began, he was stopping just two minutes in. The difference is night and day.

We then pushed things further. Over a 3.5-month timeframe, Mark dropped 15kg+ of body fat and reduced his biological age by 11 years.

Real progress. Real outcomes.

Tom, 49 - "I've got my routine back".

Tom came to me wanting to lose weight for an upcoming holiday. After struggling to shift the weight prior to this, my job was to change that. 2kg in a single week is now the new standard for us.

Craig, 40 - "Stronger mentally and physically".

With an office-based job, Craig needed a routine that was sustainable, one that prioritised daily movement while addressing spinal weaknesses and muscular imbalances.

In just two months, he progressed from struggling with bodyweight lunges to lifting 16kg each side. That’s not just a strength gain, that’s a complete shift in confidence, resilience, and capability.

This is what happens when structure meets commitment.

My Name is Lucas Sinclair, I am a Personal Trainer and Nutritionalist.

Some background: My journey started when I was 16, where I weighed less than 100lbs. I was notoriously known as the "skinny-kid" throughout school.

I decided to make a change in my trajectory, I picked top the fork and started going to the gym. almost daily. This mainly started for vanity but quickly progressed into more than that, it became a lifestyle.

What I do now: I take all of the knowledge I have collected from that experience plus the qualifications I have picked up throughout that pursuit and I help individuals to establish the most impactful route for getting you the result you are after

About me

My name is Lucas Sinclair. I’m in my twenties, and I help individuals perform better inside and outside of the gym.

My journey began at 16. I weighed barely 100 lbs and lacked direction, not just physically, but mentally and socially. Poor nutrition, low energy, and declining mental health defined a period where I felt disconnected from myself. I wasn’t just underweight; I was unsure of who I was becoming. I even found myself lying about how much I was eating just to avoid the conversations.

That experience reshaped everything.

Today, my work is about guiding others through their own transformation, not just changing their body, but rebuilding confidence, structure, and self-trust. I’ve helped over 30 individuals improve their body composition and completely reframe the way they approach training, nutrition, and themselves.
