This place is huge. Caters for all different fitness levels and offers so much more than many other gyms these days. The staff are friendly, the equipment is top notch, classes will get results and did I mention huge.


Been going to Hangar 4 and Industrial Strength & Fitness for 4 years now. Cannot rate them highly enough, from my first day there as a 15 year old girl, I felt 110% supported and encouraged by Carl, staff and all members. Always a happy and safe environment that challenges you to be your best. Shout out to all the girls out there thinking of giving it a go... so empowering and great for fitness! Defs come join the family.


Every time I come to training, everyone says hello! The classes are refreshed and no one session is the same! My motivation boosts, and I am left with a feeling of accomplishment and a reignited "can-do" approach to the rest of my day! There are even healthy choice meals available to further support me beyond the gym floor! Being part of ISF is being part of a wider fitness community that is results driven, with a genuine invested interest to help me achieve and smash my fitness goals. ISF is here to stay!! #legends


This gym has got to be the greatest gym I've ever signed up with. Carl and his team are so welcoming/supportive every time I see them. Highly recommended to anyone and everyone!!


Best gym in Melbourne!

Pretty nervous looking for somewhere to train with my son who has suffered bullying and both of us wanting to get into better shape ... also I've never trained in my life! Seriously , the best group of staff and members, everyone is really welcoming and make you feel like you belong there. Thanks guys!


Great culture, thanking Carl & Jackie for all there hard work in creating a welcoming place.  Keep it up guys!
