This summer, Isaac offered free weekly classes for kids, and my son absolutely loved them. It wasn’t just some promotional thing — you could tell he genuinely cared about giving the kids a fun, safe place to be. As a parent, that meant a lot.

One day while my son was in his class, I walked into the gym just to use the restroom. I hadn’t stepped foot in a gym in years. The young guy at the counter, stout, respectful, and incredibly welcoming, offered to give me a tour without me even asking. He walked me through everything, explained the pricing clearly, and even told me there was no contract, which has always been my biggest deal-breaker with gyms.

Isaac happened to be there too, so I asked him if I’d be able to bring my son with me when I worked out. Without hesitation he said, “Of course.” No attitude, no upsell — just kindness. Right then I grabbed a key card and paid for my first month.

Fast forward six months, and I’ve been showing up consistently ever since. The atmosphere here is something special. Everyone — not just the staff, but the members too — is positive, encouraging, and genuinely rooting for each other. You can feel the community as soon as you walk in.

The equipment is always in great shape, and there’s everything you could ask for: tons of machines, plenty of free weights, barbells, and dumbbells all the way up to 150 lbs. I’ve never once had to wait long or deal with anything broken.

What really makes this gym stand out, though, is Isaac. He’s not just an owner — he’s a leader. He puts in the work, he shows up for people, and he truly cares about everyone who walks through the door. He’s built a place that feels welcoming, motivating, and real. In my opinion, that’s rare.

I can honestly say I love this gym. If you’re looking for a place where you’ll be supported, challenged, and treated like a person — not a number — this is the one. I highly, highly recommend it to anyone and everyone.

Isaac’s is a must! I would give 10/5 stars if possible. Awesome place, awesome staff—so helpful and kind. It’s the perfect spot for competitive lifters, but also incredibly welcoming for anyone just starting their fitness journey.

We were visiting from Cincinnati for the week and were blown away by the atmosphere and community here. Huge thank you to Isaac, Kirsten, and Jacob for making our experience so great—we genuinely can’t wait to be back in town so we can come to Isaac’s again!

Issacs is 110% the best gym in the Knoxville and surrounding areas. Me and all my boys travel 35+ minutes just to experience the old school vibes. Highly recommended if you are in pursuit of hard, heavy, and humble training. As for Issac, he is a great man, extremely respectful, honest, and a great owner.

Been going here for a little over 6 months now. If you're looking for a no-nonsense gym, this is it. Kirsten Nguyen is AMAZING. If you're looking for a personal trainer who will not only push you to reach your physical goals but will also listen to you and be a friend, she's your girl. If I could give higher than 5 stars, I would. Highly recommend

Isaac is a super chill guy, one of the best gym owners I’ve met by far. My wife and I’s first encounter with him felt like we’d known him for years even tho we had just met. The gym itself is awesome, the pictures do a terrible job at capturing the size of it. Go down and check it out for yourself, I’d recommend this Gym to anyone.

I just restarted my gym journey and Isaacs has been awesome. Him and his staff are also friendly and extremely helpful, while being motivating. The gym itself is spaced out well and clean. This is where I’ll get back into my healthy habits and get my gains back!
