TESTIMONIALS

  • A side-by-side comparison of a young man showing his fitness progress, shirtless, taking mirror selfies in different locations

    "I've always trained consistently, but I was cycling through cookie cutter programs without much direction. Jacks coaching gave me the structure, clarity, and results that finally reflect the work I'm putting in. Looking back now, that's a powerful feeling and was totally worth the investment"

    Osi went down from 96kg to 91kg | 3 month transformation.

  • "I've shared a bond with Jack over the course of many years. I can tell you first hand that his knowledge of resistance training is high calibre. We were able to focus on building a healthy relationship with food, while eating in a slight deficit, alongside maintenance calories. Cardio is no issue for me, so after a few months of being on program and eating the right fuel, I started to take shape and look leaner"

    Sam went from 91kg to 90kg, pure fat loss and muscle gain | 2 month transformation.

  • “Having suffered a problematic back injury years ago, I now feel much stronger, more confident, and more active thanks to Jack. The level of accountability towards training each week was without a doubt the push I needed. I still have a long journey to go, but it's been one of the best decisions I made for my health”

    Bruno went down from 124 kg to 112 kg | 5 month transformation.

  • Side-by-side mirror photos of a young man taking a shirtless selfie, showing physical transformation. Left image shows him facing forward with a neutral expression, wearing gray shorts and a watch. Right image shows him in profile with a slight flex, wearing black shorts.

    “I came in wanting to nail the basics. Jack’s program and constant input lead to an advanced regime where I’ve added muscle, dropped fat, and can actually run without gassing out. I was unsure of my expectations, but Jack’s level of experience, insight and care has exceeded all - it was built around me, and that’s the defining difference!”

    Sean went up from 89kg to 92kg | 15 week transformation

  • Side-by-side comparison of an elderly man before and after a weight loss transformation, wearing blue shirts and dark shorts, standing against a plain white wall.

    “Some people don’t get to see what it takes to start again after a fatal collision - that caused me life altering injuries. I crossed paths with Jack after my time in hospital, unsure if I could even train again. I’m over 26kg down and stronger than I was before thanks to the guidance around my food and training. Now, I continue to follow the direction he plans for me”

    Rich went down from 164kg to 138kg | 6 month transformation

A shirtless man with long hair, wearing a backwards cap, black shorts, and a wristwatch, stands with his arms flexed against a dark background with the words "ROBBERTSON" vertically displayed on a large gray banner.

MEET COACH

Jack

I’m an accredited Hyrox & REPS certified Personal Trainer and founder of JackedFitness. Transitioning from a competitive rugby union athlete to the path of an aspiring PRO bodybuilder, I know exactly what it feels like to want more for yourself in this life.

Injuries and setbacks stripped a great deal of my identity, sustaining multiple surgeries and painful nights of unrest. For years, I spent far too much time focused on the things I didn’t like about myself, and I lost my way in the process. To be truthful, I lost my direction.

Since then, I have used the gym to change my life and not just physically. It taught me to be resilient and to stay planted during those low points in life. When you are truly rooted in what you believe in, a tree stands tall through all four seasons. You grow. Every. Single. Year.

I have been a student of the fitness game for many years. Now, I consider myself a coach to the upcoming generation of men and women, both young and old, who want to succeed in the gym! 🔥

Why Choose Online Coaching?

Online coaching isn’t just about workouts and macros. It’s about meeting each other where you are and showing you what you’re capable of, even when you can’t see it yet. This journey is personal to each individual, and I’m here to guide you through yours — facing the many trials and tribulations step by step, rep by rep.

I design tailored plans to help you become comfortable being uncomfortable, without losing sight of your goals through the virtue of hard work. Whether you're juggling a demanding job, rebuilding your confidence, or aiming to compete, this is your space to transform. I will not let you fail! Let’s get these gains fam.

FAQs

How long does it take to see results?

Most clients start seeing noticeable changes within just two weeks — The real magic happens with consistency.

I ask for a 90-day commitment — not just to me, but to yourself. This timeframe gives your body and mindset the chance to properly shift. In just three months, you’ll be amazed at how far you’ve come.

How long is the commitment?

It depends what your goals are. For weight loss, it is not necessary. Losing fat is primarily driven by diet. For gaining muscle, a gym is very beneficial, but it is possible to build significant muscle with at home equipment or an outdoor gym.

Do I need a gym membership?

I’m in your corner every step of the way. I stay closely involved with each client — reviewing your weekly progress, checking in on your food, weight, tracking, macros, and overall mindset. My coaching is personal, not cookie-cutter. If you need help, you’ve got it.

How much 1-on-1 support do I get?

I've tried weight loss programs before. What makes this one different?

This isn’t a generic program. This is a customised, coach-guided transformation built around your goals, your lifestyle, and your roadblocks. I’ve walked this path myself, and now I help others do it and follow through with it.
