About Josh Aremu

I believe fitness should be principled, purposeful, and personal. My coaching is built on three core foundations: movement, strength, and nutrition—applied through a system that’s tailored to your body, goals, and life.

My background in sports gave me early insight into discipline, resilience, and performance. That passion evolved into a career helping others move better, feel stronger, and live well through a principled-based coaching system I’ve refined over the years.

Through working with hundreds of clients—from new mums to high-performing professionals—I’ve seen the body’s ability to adapt, recover, and transform. I’ve also learned that fitness is more than sets and reps—it’s about building a life of capability, confidence, and freedom.

I’m certified in NASM Level 3, CPPS Level 1, and pre/post-natal training, with specialized expertise in kettlebell and suspension systems. I’m also currently completing OPEX Fitness and Precision Nutrition Level 1 to further expand the depth of support I offer.

YOur Fitness Journey

At 351 Fitness, every coaching relationship starts with a clear, structured assessment built around four key pillars

  1. Lifestyle
    We look at your sleep, stress, work demands, habits, and recovery to understand how your lifestyle supports (or limits) your progress. This helps us design a plan that actually fits your real life.

  2. Body Composition
    We assess body fat, lean muscle, and overall body composition so we know where you’re starting from and how to align training and nutrition with your goals.

  3. Movement Patterns
    We evaluate how you move – your range of motion, stability, control, and mobility – to spot limitations, reduce injury risk, and choose the right exercises for your body.

  4. Work Capacity
    We measure how well you handle different types of training: strength, strength endurance, and conditioning. This shows us what you can currently tolerate and how to progress you safely and effectively.

Together, these four pillars give 351 Fitness a complete picture of you – so your programme isn’t generic, it’s built for you.

Let’s work together.

Real People. REal Results

  • “I cannot recommend Josh highly enough! After struggling with shoulder issues for several months and enduring chronic lower back pain for over two years, I was starting to lose hope. However, within just four weeks of working with Josh, I experienced major improvements in both areas. His expertise, personalised approach, and deep understanding of body mechanics have been absolutely life-changing. Josh is attentive, patient, and truly invested in his clients’ progress. Every session has been targeted, effective, and tailored to my needs. Thanks to Josh, I’m now moving pain-free and feeling stronger than ever!”

  • “Josh is a wonderful PT. He both understands my needs and challenges me to be a better athlete. I had two big surgeries in the past year and he has helped me re-focus on strengthening the muscles around the surgery points. He is very knowledgeable of his craft and I highly recommend him for PT support.”

    Janet J.

  • “I have been Zoom training with Josh for about 18 months and i can honestly say he is an absolutely fabulous trainer. he has a completely uncanny ability to know when to increase the work load and when to consolidate he is also very sympathetic to aches and pains and at a moments notice can switch to a remedial workout when required i without hesitation give Josh 10 out of 10 in all categories of PT oh and we have a good laugh during training as well .”
