This place is truly life-changing! The trainers are amazing — they genuinely care about each client and are dedicated to helping everyone build strength, endurance, balance, and confidence. Plus, they make it fun! Walking through their doors was the best decision I’ve made in years. I’m so proud of how far I’ve come, and though I still have a way to go, I know I’m on this journey with the best support possible.

Let me start by saying I don’t like to exercise. So if I tell you I enjoy a workout place, you know it means something! Alloy Naperville South has amazing, knowledgeable, motivating, NICE trainers. They know how to adapt workouts to make them more challenging for people that need that extra boost, or can offer alternative exercises for those who may need a bit of an alternative exercise. Workout classes are small so that you get individual attention. The hour goes quickly and you walk out of each session feeling accomplished. I definitely feel less tired and stronger after a session at Alloy! Get up off the couch and schedule an introductory meeting today. I know you’ll be happy you did!

I’ve been really impressed with the level of personal attention at Alloy Personal Training. Rena and Matt are both excellent trainers. I was initially hesitant to join a small group setting, having experienced too many “one size fits all” approaches in the past. But Alloy truly personalizes the workouts to maximize your experience and even provides alternatives to address any specific needs or limitations.

Alloy offer a great environment that is personalized to each person’s circumstances. The trainers are great — very professional and attentive in creating an individualized and “low-pressure” atmosphere — so the sessions are challenging but doable. The flexibility takes account of those of us who are “older.” Highly recommended!

I Love Alloy!!! The trainers are amazing! They always take extra time to make sure you are doing the exercises properly and always encouraging you to push yourself when they can tell that you are capable of doing so! I love the small class size which allows you to get the extra attention you may need. Very friendly atmosphere among the classmates as well. Been attending classes for about 6 weeks and I really see and feel the difference! Give it a try! You won’t regret it!

I love Alloy! The trainers are so knowledgeable and kind. The workouts are challenging but the trainers always provide modifications so it is attainable for all fitness levels. The small group gives the trainers a chance to correct form and provide feedback. The small group also gives everyone the chance to get to know the people in the class as well as the trainers. There’s a reall feeling of community after we accomplish hard things together!.

Awesome place. My sister and I needed to start a weight training program and she found Alloy. It’s a small group at each session so that the instructor can give us all the exercises & modifications if needed. The trainers are professional and encouraging, plus we’ve met some great people and we actually enjoy working out now!

I absolutely love working out at Alloy! I’ve never been someone who could push myself to do strength training on my own, but the team at Alloy somehow makes it fun—which I didn’t think was possible. The workouts are always challenging in the best way, and the coaches are so supportive and encouraging. Every session feels personal, motivating, and never repetitive. I’m getting stronger, more confident, and actually look forward to going—something I never thought I’d say about a gym. Highly recommend to anyone who wants to get fit in a positive and fun environment!

I’m 68, with stability issues from prior injury. I was uncertain before I came in that they could accommodate my limitations in a small group workout setting. From the moment I walked in the door and met with Rena to set my fitness goals I knew I had no reason to worry. I felt very welcome. Once I started my regular workout sessions I was amazed at the skill and compassion of the trainers. Everyone in the small group does the same group of exercises for the daily session but they offer several different modifications for all fitness levels. Matt is the trainer I’ve worked with the most and he very quickly came up with the best way for me to be safe and still get a challenging workout. Alloy is a very friendly and supportive workout environment. I highly recommend them!

I was hesitant to join for fear I wouldn’t be able to keep up with the small group. I shouldn’t have been. The trainers here are excellent. They are very knowledgeable and extremely kind. The modifications they have for every exercise seem endless but most of all the way they are presented to you is so discrete others in the room don’t even realize you are doing them. I’m 68 years old and my usual group ranges from 40-70 at all levels of fitness. In just two months I see such a difference in my stamina.
I’m overjoyed with the quality, friendliness and knowledge of the trainers at Alloy. I look forward to my sessions.

Love this place! The trainers are amazing and the small group approach can't be beat! All levels of fitness are welcome and the trainers make sure to show any accommodations or variations necessary to ensure everyone is able to get a quality workout in. The format of a warm-up, 6 different exercises over 3 rotations, a finisher at the end and post-workou cool down/stretching cannot be beat. I leave after every class feeling good and can't wait until the next class. I would highly recommend Alloy because they're the real deal for reaching your fitness goals and exceeding your expectations of yourself!

When I started here I had not worked out in 7 years, so I was concerned about whether or not I would be able to do these workouts. The trainers are wonderful, they make adjustments to the exercises so they work for you. I love the community of Alloy and all of the support from the other members. I highly recommend Alloy.

Alloy is the best! I have not worked out regularly for too many years! Matt has encouraged me along the way! I started in May and am already feeling the difference. I even look forward to going!

Great Experience at Alloy Fitness South Naperville!
I absolutely love my experience here! What truly sets this gym apart are the trainers. They are incredibly attentive, always making sure we're performing exercises with correct form. The small group class setting is a huge advantage, allowing for that personalized attention you often don't get elsewhere.
Every session is engaging because they incorporate a wide variety of exercises, keeping things fresh and challenging. Beyond the workouts, the atmosphere is consistently great – it's a really positive and motivating environment to be in.
I actually moved to the South Naperville location as soon as it opened because it's so much more convenient to my house. Having tried a different location previously, I can confidently say the quality and dedication remain consistently high. If you're looking for a supportive and effective fitness community, I highly recommend checking them out!

I decided to try training in person since the motivation was not there for me at home. I met with Matt and he gave me realistic advice regarding what I wanted to do for my fitness journey. And let me tell you, Alloy doesn’t disappoint! I go for the early morning session which works best for my schedule. I love that option. And the staff is great to work with. After 10 minutes, if you aren’t sweating, you are doing it wrong. I enjoy every session I attend. I highly recommend Alloy for your training.

Matt, Reena, Justin, and Matt encourage us to give it our all every day! If it's been a while since you were last at a gym, like me, the strength resistant type training allows more freedom of movement and reduces a risk of injury. We're all in this together!

I’ve been to many gyms—Orange Theory, Lifetime, VASA—but this one has been by far the best experience I’ve had. The trainers truly take the time to get to know you and give you just the right amount of individual attention to know when to push and when to support. The workouts are always diverse and challenging, helping build not just strength, but flexibility too. One of the hardest things about finding a good group fitness class is sacrificing personal attention, but that’s not the case here. The class sizes are just right, allowing the trainers to correct your form and help you grow safely and effectively. I can’t recommend this place enough!

Absolutely love this gym! From the moment I walked in, I was greeted by such a friendly and welcoming community. The classes are the perfect size, never overcrowded, so you get the attention and space you need. Each workout is unique and challenging in the best way, keeping things fresh and exciting. The trainers are incredible—knowledgeable, motivating, and they even know you by name, which makes the experience feel so personal. I also appreciate the diverse mix of people in every class. No matter your background or fitness level, you’ll feel right at home here. Five stars all the way!
