What our members think of us
This is the perfect gym for motivation, there’s no going for a couple of weeks and then giving up. You’re encouraged to push yourself forward each week. It’s also fun with plenty of banter. Love it
Honestly…. This is the best gym experience I have had. You can tailor it to your level and I always feel that I have made the most of the hour that I spend with the trainers. Cannot recommend it enough.
Nick, Reg and the team have created a brilliantly supportive community who have helped me advance my fitness journey. And they do it with a smile and some very dodgy soundtracks. Thanks guys.
Exceptional gym with tailored training plans and knowledgeable staff. Clean, supportive, and results-driven—highly recommended.”
Really great training experience plus hard and fun. Love the team so helpful and friendly. Definitely recommend to train there.
Fabulous friendly place to train . The coaches are all knowledgeable and want the best for us . I absolutely love attending my training sessions and enjoy every minute of being there .
iDFitness is by far the best PT/fitness studio I’ve ever been to. The training sessions with the team: Nick, Reginald, Zack and Jamie are excellent. The banter and music are second to none! I’ve got in shape, lost baby weight, made some lovely friends and become the strongest I’ve felt in a long time! Nick has created such a wonderful community, attending sessions always sets me up for the day. I cannot recommend this place more highly enough!
What sets IDFitness apart is the holistic approach they offer. Not only do they focus on fitness, but they also provide incredible support in areas like nutrition. The online portal they offer is a game-changer for me. It’s packed with valuable information, perfect for keeping me on track or getting back on the bandwagon when life gets in the way.
I’ve never felt more supported, and it’s been a key part of my success. If you’re looking for a place that genuinely wants to see you thrive in every aspect of your wellness, IDFitness is it! Highly recommend.

ID Fitness is personal training for everyone – the vision embodied by founder and head coach, Nick Collins, as well as all the PT’s and members who are part of this special community.
I’d been looking to join a local gym in Windsor for some time and after doing lots of research and seeing all the positive reviews, decided to give ID a try. I am so glad I did.
When I first walked in I was unfit, self-conscious, unfamiliar with gym equipment and my exercise clothes had seen better days. I started on their 8 week programme and now after only 3 months I barely recognise myself. The classes and equipment are varied, flexible and fun, with small group tailored PT sessions as well as larger classes. The environment is welcoming and clean, where everyone is treated with encouragement, kindness and respect regardless of ability, age or experience. Nick and his hand picked team are industry experts – highly professional and caring, listening to and positively challenging their members to help them achieve their health and fitness goals through building consistency, strength, technique and social connection.
I love coming here and have met some lovely people along the way too, which was an unexpected bonus. I look forward to continuing to train at ID, and feel excited about achieving my health and fitness goals with their support.
It also feels great to support an independent business.
