Jack Gunn, Relentless Strength Coaching

About Me

My name is Jack Gunn and I am a young, dedicated strength athlete from Hinckley, Leicestershire.

I hold a Level 2 qualification in gym instruction and a Level 3 qualification specialising in personal training. I have competed in multiple powerlifting competitions, earning regional and national titles and records along the way.

I have a huge passion for the gym, strength training and helping people become stronger, more confident versions of themselves. I started strength training at the age of 15 and, over the years, I have completely transformed both my strength and physique, going from a skinny, insecure teenager to a confident and driven strength athlete.

Like many people, I made mistakes early on in my training, and some of those had a lasting impact. My goal is to help you avoid those same mistakes, giving you the right guidance from day one so you can train safely, effectively and with purpose.

Friends, family and colleagues have always described me as kind, respectful and hard-working, and I bring those same values into my coaching. I look forward to giving you my full support and helping you reach your strongest self.

1-to-1 Personal Training

Train with confidence. Build muscle. Reach your strongest.

Feel nervous walking into a busy gym? You're not alone. For many people, the hardest part of starting their fitness journey isn't the training itself — it's having the confidence to step into a crowded gym and know what to do.

That's where I can help. I offer 1-to-1 personal training in a private gym facility, giving you the space, support and attention you need to train with confidence. With access to state-of-the-art equipment and a completely private training environment, every session is focused entirely on you — your goals, your technique and your progress.

Every session is tailored to your goals, experience and ability.

Expert Strength Coaching

Progress You Can See

Whether your goal is to get stronger, improve your physique or simply become more confident in the gym, we'll work towards measurable progress together.

You Don't Need to Be Experienced

You don't need to know how to squat, bench or deadlift. You don't need to be incredibly strong. You just need to be willing to start. I'll guide you through every step and help you build the skills, confidence and strength to become the best version of yourself.
