I’m a male in my 40s with two young kids, and like many people my age, I’ve picked up a few aches and niggles over the years. Training with Scott at The Core Fitness Training Club has genuinely made a huge difference to both my fitness and my day-to-day lifestyle. The sessions are always well planned, challenging without being overwhelming, and tailored to what I need. Scott understands how to work around injuries and focuses on improving strength, mobility, and overall fitness in a way that’s sustainable. Since training with him, I feel stronger, have more energy to keep up with my kids, and those everyday aches have improved significantly. It’s one of the best investments I’ve made in my health. I can’t recommend Scott and The Core Fitness Training Club highly enough. If you’re looking for expert coaching in a welcoming environment that delivers real results, this is the place to be.

As someone pushing 80 with an aversion to gyms I was very sceptical when my GP recommended weight training for bones and general health. I am amazed and delighted to find my weekly sessions with Sabrina are so motivating, very enjoyable and life changing. She intuitively knows my capabilities, encourages me to push even further, and at the same time looks after me well, knows my limits and advises on maintaining good health and fitness going forward into older age with optimism. I heartily recommend Scott and his team at Core Fitness.

Our son, who has special needs, does weekly training sessions with Scott at his residential setting. Scott is absolutely fantastic and it is heartwarming to see how much he cares about our son. Within a short period of time, we have seen a massive improvement in our son’s mobility and fine motor skills, all thanks to Scott’s patience, motivation, and perseverance. These weekly sessions have become one of the highlights of our son’s week. Scott is really making a difference and we are so thankful for all his support!

I have been a client of Scott’s for 3 years. I am in my late 70s and have always kept fit. Scott takes fitness to a new level for me. He is excellent.

Highly recommend Joe! He is incredibly intuitive; he figured out my capabilities quickly and builds my strength up so gradually that I don't even realize how hard I'm working until I hit a milestone. After 6 weeks, I’m amazed at how much strength I’ve built up and can now lift my own body weight He has a very clear and encouraging teaching style. He’s great at reading what you're capable of and tailoring the variety of exercises to match. I always leave sessions feeling confident and looking forward to the next one."
