This gym is exactly what this county needed. The staff is second to none. The equipment is top tier. The pace has such an amazing vibe. It truly is a gym family and everyone there uplifts everyone else. I will never go anywhere else. You should try it because it will become a home.

This is by far the best gym I’ve ever been to. If you’re looking for something beyond the typical commercial gym experience, this is the place for you. The warehouse-style setup, paired with unique equipment, makes every workout feel different and exciting.

I’ve been a member since day one and can confidently say I’ll never leave. The staff is incredible and always welcoming, approachable, and genuinely supportive. Even if you’re new to the gym environment, the vibes and community here will make you feel right at home and motivate you to be your best.

Cleanliness is always on point, and members respect both the space and each other. This gym continuously reinvests in itself to provide the best experience possible for its members.

I can’t say enough good things about this place. If you’re considering it, give it a try. You won’t be disappointed.

Not sure what more I can say than this is the best gym I’ve been to. Phenomenal environment, great staff, top of the line/unique equipment, 24/7 access. Couldn’t ask for a better gym.

I’m not a body builder or power lifter. I enjoy working out at my own pace. Unlike other gyms. I’m allowed to do so here. If I wanted to become a powerlifter or body builder. This place is well equipped to do so. The best part to me is the friendly staff. I’m not looking at as a “gym rat”, they took the time to talk to me and help with form. Next time I walked in. I was greeted by name. Fell in love with the place and instantly cancelled my other membership. I would include a photo but that means I’d have to walk up to the other 30 people here and ask them for their permission. Take the 10 minute tour and I Guarantee you’ll enjoy yourself as well.

Incredible gym! Nothing compares! The best gym within 50 miles from our area. I cant even walk into another gym without walking right out. This gym exceeds my expectations and offers every top of the line equipment you could ask for. Not to mention how clean they are! Cam and Chase are super friendly and make you feel so welcomed! 100% recommend!

Best gym in Kankakee county! Cam and Chase are awesome and are always willing to assist with a spot or explaining a machine.

The vibes are high and the music is fire! Overall super clean and well-maintained. The sauna may just be the best part!

Make the switch to UNKNOWN.

top notch new gym in the area! great owner/staff. Clean, nicely laid out, open air due to building structure. doesn’t feel stuffy. Sauna addition to the gym is a must in my opinion. love that we got another GYM and not another health/fitness center. nothing wrong with the other, just more of an fit for what I’m chasing! highly recommend y’all get up in here! 24/7 gym and they offer day/week packages as well! major!

Owner was extremely accommodating & down to earth. Spacious facilities. More than enough equipment to achieve whatever your fitness goals may be. Supporting this gym supports small business, your backing the blue & combating an America run by corporations that could care less about you. Check this place out. You won’t regret it 💪🏼
