    Long overdue review for Peach Body Studio! I signed up for…read moreone of their programs last year and truly enjoyed my experience. One of the things I loved most was the atmosphere--it's an all-women's studio, which made it feel comfortable, supportive, and never overcrowded or overwhelming. All of the trainers are amazing--encouraging, knowledgeable, and genuinely invested in helping you succeed. I especially appreciated how welcoming everyone was, no matter your fitness level. Unfortunately, I wasn't able to renew my membership due to what I initially thought was a minor walking injury I experienced in June. After an X-ray, my doctor said everything looked fine, so I continued working out at Peach Body with modified exercises. Toward the end of my membership, I even transitioned into personal training sessions with Cheli, which helped me tremendously. I had every intention of rejoining after my six-month membership, but I had a trip to Spain planned. When I returned, my knee still wasn't improving. I ended up seeing a new doctor and, after an MRI in January, found out I had a torn meniscus. Fast forward to February, I underwent meniscus arthroscopy surgery. I'm currently on the road to recovery (still in a full leg brace), but I'm hopeful and looking forward to rejoining Peach Body Studio in a few months once I'm fully healed. Overall, I highly recommend this studio to anyone looking for a supportive, empowering environment with fantastic trainers!

    I've been going to PeachBody Studios for about a year now, and I can honestly say it's been such a…read morepositive experience for me. I actually found PeachBody after having a really bad experience at a previous gym, so I was a bit hesitant at first. But from the moment I started here, everything felt different. The environment is welcoming, supportive, and truly empowering. What I appreciate most is how comfortable I feel during my workouts. It's not intimidating, and there's a strong sense of community. The coaches are encouraging, knowledgeable, and genuinely care about our progress. They always striving to educate us--whether it's proper form, technique, or understanding how to get the best results and our diet which makes a huge difference. The workouts are effective and focused, especially for glute and full-body sculpting. I've noticed improvements in my strength and confidence, which has been really motivating. I'm really grateful I found this place. It's a space where I feel supported by others and encouraged to keep showing up for myself. Highly recommend to anyone looking for a positive, women-focused fitness community! I would like to add too HUMOR! Expect To Laugh A Lot!

    I originally came in just wanting to fix my form and learn how to lift properly, and that's what…read moreI've been getting. Kacy is big on progression and basically operates under the assumption that you can always go up in weight, which has pushed my strength up (especially hip thrusts and RDLs). It's small group training, which keeps the energy up because everyone's working at the same time. He'll keep you accountable and make sure you finish your sets and there's a decent chance you'll leave with a random nickname you didn't ask for but it does keep things entertaining. In my first month I've already seen measurable changes in strength and body composition, so it's been interesting to see the progress show up pretty quickly. Curious to see what the next couple months look like.

    My girlfriend had been working with a conditioning coach for some time but saw minimal results. We…read moredecided to shift focus and look for a strength-based training approach, which is when we found Kacy. We met with Kacy in person, where he clearly explained how his program works, reviewed pricing, and discussed the nutrition expectations that accompany the training. He was very straightforward, professional, and understanding--especially recognizing that it can be difficult to transition away from a previous coach. Training began shortly after. Sessions can be busier during certain days and times, typically running 60-90 minutes, with multiple clients training simultaneously. Despite this, you receive excellent value for the cost. The pricing includes gym access, which is a great benefit. Kacy maintains a professional environment while keeping sessions engaging, motivating, and appropriately challenging. It's important to note that this is primarily a group training format. While Kacy provides guidance and instruction, he is not overseeing every single repetition. For those who are completely new to lifting, discussing one-on-one sessions would be beneficial. Overall, we highly recommend Kacy. Thank you, Kacy, for your patience, professionalism, and continued support

    My review is for my trainer Kevin Abandy. Just wanted to say he is a very knowledgeable trainer. He…read morewould first listen to your goals and also take into consideration of your current body conditions and injuries and work around that. Before the start of every single session he would ask how are you doing today to ensure he can address any issue you may have that particular day before starting. He does not want you to aggravate any injuries (he would also get on my case for over stretching due to my existing injuries haha). But a big thing for him is to instill having the right technique. Outside of the gym, he would text you the workout of the day, so you can track progress, tries to hold you accountable for having the nutrition, sleep, and would be very responsive to text or call anytime. The only knock on him is it's too bad he can't observe me on every single rep but that's because I signed up for his cheaper group session rather than 1 on 1 in which he also offers.

    First, this is a great facility. It is always clean, well-maintained, well-ventilated, and has…read moreeverything you need to get a good workout. But this is not a gym; it is a training facility where you work with trainers to tackle your physical goals. Next, this is about my trainer, Kevin Abandy. Kevin has been my trainer for exactly 8 weeks now and he is awesome! I made the decision to get a trainer after my birthday to truly invest in myself. You can invest in your own skills and education, but the return is almost always indirect. But with a trainer, specifically Kevin, I gained 8 lbs of muscle mass and lost 8% body fat (approx. 13-lbs of fat) after 8 weeks of training with him. Also, at the start of my training, I had back pain (from past injury to T12) and knee pains (from under the kneecap). Through Kevin's program and coaching, my pain has been reduced to near 0 with full mobility -- like squatting all the way down and up with 200-lbs of weight on my shoulders with no knee pain. I would give a 1-star review to keep it from getting crowded, but it would be hard for me to not tell others about the good that comes out of this place. My mom is 70 and she's training with Kevin too! And the story is the same for her... knee pains - GONE. Back pains - GONE. If you're reading this and decide to get a consultation with Kevin, please let him know you saw Alex's review so he knows his method is making an impact.

Classes are about an hour in length and there were fun challenges each month. For example, there was a May "bingo" challenge to fill up the entire bingo card with different small goals & prizes for participants. I was able to meet people, be physically pushed to lift heavier, and have my progress be monitored a number of ways. My meal logs were accessible to the owner, Fani, & her team to help me stay accountable, my body was measured using measuring tape at the beginning and end of my time there, and my body metrics were analyzed using a body composition scale.

I would have never considered myself "overweight" but knew I needed to lose a few pounds. I've tried the traditional membership gyms but always found that I would lose interest or motivation. When I started inquiring about personal trainers, Mia was very prompt at answering. During our consultation I did a body fat scan and was shocked to find out that I was nearly 25%. We talked and I learned that it was less about the weight and more about body composition and fat/muscle percentages. Due to my work schedule we were able to meet twice a week for an hour a session. Mia adds good variety to our workouts and I definitively know that I push myself more during our sessions that I normally would have if I were doing the workouts by myself. She also places an emphasis on nutrition and offers advice on what to eat and what to stay away from. The last couple of years my diet has gotten progressively worse, and she's been a great help in getting me back on track. I've noticed that I've started making much healthier choices in the foods I eat. still have a ways to go but would highly recommend Mia for helping you get you to your goals!

When the manager came out, the focus seemed to be on how I entered and whether I rang the doorbell rather than the fact that I had a confirmed appointment and did not know their process. After I left, I received a phone call that felt more focused on explaining why the situation was my fault than resolving the miscommunication. This gym may be a good fit for others, but based on this experience, it was not the right fit for me.

Jeff's knowledge and expertise immediately stood out--he has a Bachelor's degree in Kinesiology with an emphasis in Strength & Conditioning, as well as a Master's degree in Athletic Training. He truly understands the body and uses that education to make sure you're not just getting stronger, but doing it safely and correctly. Every workout and movement was thoughtfully designed around my injury, which made a huge difference in my recovery. Not only has he helped me rehab, but he also created a personalized meal plan and weight training program that helped me lose 56 pounds. Beyond the physical changes, he's helped me improve my balance tremendously and build a level of confidence I never thought possible. Jeff genuinely cares about his clients and their progress.
