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.
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.
Thank you x
