AMAZING! Top 10 on the bucket list! I was sent here as a gift, with no preconceptions and I was blown away by what I experienced. Regardless of your capabilities, interests, past experiences you will find immense reward and achievement by completing simple tasks where the only challenge is yourself. If you hate the gym like I do, this is the fitness playground for you, and if you love the gym you'll be pushed beyond your sets and reps. I highly recommend anyone that wants to have fun, exercise, meet a wide range of people, challenge themselves, or improve their mental wellbeing to give it a go. It's something anyone can do, and everyone should do!

This is an incredible place! Perfect for training real ninja warriors of all skill levels and ages. If you want to have a good time and experience unforgettable emotions, this is the place for you! The excellent coaching staff will advise and teach you the techniques to overcome obstacles!

My children, both boys, have attended for over a year now. Emily and Dion are both fantastic with discipline and care for the children. The boys have made exceptional progress and are still both very excited about their training each week. Their full body strength has hugely developed and confidence in many areas improved. The holiday courses they offer too are motivating and inspiring, with 100% focus on the activity, rather than just babysitting like some camps seem to deliver. Can't recommend them enough!!!

Such a great facility, my son loves training here, when he's not Ninja Warrior training, he's talking about Ninja Warrior training. The kids get so much encouragement as Dion and the other coaches help them to achieve their potential, the classes have lots of different ability levels and everyone leaves with a sense of achievement. It ticks so many boxes, physical activity, mental wellbeing, confidence building, problem solving and teamwork as well as being lots of fun. Can't recommend it highly enough.

This place is a real gem of a find! My son is having the time of his life here and feels so motivated at the end of each session. The coaches are incredible! Not only knowledgeable but sincerely enthusiastic and will do their utmost to instil confidence and inner strength. An absolute must for all kids. Thank you True Function Ninja Warriors :)

Wonderful facility matched only by the passion of Dion. Nothing else like it in the Uk. Look forward to training there again soon.

THE Ninja Gym to be in Europe! A lot of show like obstacles which are great fun, but also a perfect gym for everbody who loves to move. Besides the Ninja Training, you can train your gymnasticst skills there on a huge tumbling floor but also work on your Parkour skills or just check in for a functional workout in the fitness area. Not only for adults, it´s also great for kids which love to move. The kids area is almost as big as the adult area. You are looking for a location for a kids birthday party? Just give them a call and ask for details!

This place needs to come with a warning..... YOU WILL BE HOOKED! :)
The facilities are absolutely top notch. The team and community are fantastic, with motivation and support coming from everybody. It doesn’t matter if you’re a top class athlete or someone starting your ninja training journey you will always feel welcome and part of the family. Last but not least... Dion the driving force, HEART & SOUL of TFNTG. His passion for training is only surpassed by his passion for teaching and helping other reach their full potential.
I look forward so much to every training session and watching us all grow from strength to strength.

You will not find a more fun, dedicated and enthusiastic Ninja Training Coach as Dion Trigg anywhere! I started training at True Function about a year ago, and it's the best fitness decision I've ever made - never been stronger and leave every time with a huge smile on my face! Get down here
