About
Hi guys, I’m Callum and I’m a level 3 qualified personal trainer at The Greenwich Centre. With over 10 years of gym experience, I aim to provide efficient and easy to follow programming, and create a safe and encouraging environment in which you can achieve your goals.

I have extensively trained in powerlifting, as well as being a passionate martial artist, holding a brown belt in Judo, I’ve practiced Jiu Jitsu for the past three years and I’ve even boxed professionally at Wembley Arena (please ask me about it, I love talking about it). I aim to draw on all of my experience to make workouts exciting, keep my clients progressing and make the gym experience something you look forward to, rather than a chore.

If you want to gain weight, lose weight, get stronger, get faster, get fitter, I’m your man, look forward to hearing from you!

I've been working with Callum for the past 3 months, and the transformation I've experienced is nothing short of amazing. Before starting with him, I struggled with consistency and motivation in my fitness journey. Now, thanks to his expert guidance and unwavering support, I've not only achieved my fitness goals but surpassed them.

Callum is incredibly knowledgeable about all aspects of fitness and nutrition. He took the time to understand my specific needs and tailor a program that was perfectly suited to my body and lifestyle. Whether it was weight training, cardio, or meal planning, he had a solution for everything. His comprehensive approach ensured that I was progressing steadily and safely.

What sets Callum apart is his genuine passion for helping his clients succeed. He's always upbeat and encouraging, making every session something I look forward to. He pushes me to my limits but always in a way that feels achievable and empowering. His positive attitude is contagious, and I've found myself more motivated than ever to stick with the program.

One of the biggest changes I've noticed is in my confidence. Not only do I feel stronger and more energetic, but I also have a much better understanding of how to maintain a healthy lifestyle on my own. Callum has equipped me with the tools and knowledge I need to continue progressing even outside of our sessions.

If you're looking for a personal trainer who is truly dedicated to your success, look no further than Callum. He's professional, personable, and exceptionally skilled. I can't recommend him highly enough. Working with him has been one of the best decisions I've ever made for my health and well-being. Thank you, Callum, for helping me become the best version of myself!

Had an unreal taster session last week with Cal, proper friendly guy and I genuinely loved the session. Tried a bit of boxing on the pads at the end too?! It was great!
