Inviting and friendly gym culture that is highly inclusive.I joined Wonderfly to meet a goal to run a 10K in under 75 minutes without having ran since high school (13+ years ago). I trained with their running and speed coach for 3 months and out performed my goal in 55 minutes, placing in the top 11% of the race. Needless to say this is the start of me getting back in shape and regaining confidence.Thank you Wonderfly!Christine BrownChristine Brown1667877710 ★★★★★ Hands down, the best choice I’ve made is training at Wonderfly. Friendly staff! DJ is an awesome personal trainer. The workouts are fun. Exercise is new to me. He gives hands-on feedback and adjustment during the workouts. You have taken me to the next level, and I am thrilled with the routines you have developed for me. You keep me interested and motivated. Thank you for taking me on this journey. I highly recommend this gym to all my family and friends!Kala JenkinsKala Jenkins1657896651 ★★★★★ The staff was amazing. Everyone is always friendly, welcoming and polite. I always felt very comfortable when attending any class. You can tell they have a true passion for Fitness, down to how they dress, there knowledge on fitness and how to safely workout without injury. I have even met some women here and become friends after my trail with the program. If you want a fitness program and facility that focuses on people helping people this is the right place.Hal PalHal Pal1654874635 ★★★★★ I started searching for a personal trainer a few months ago. Due to having lung damage my health wasn’t great and I just needed to improve my overall health and well-being. I wanted to improve my endurance and lung capacity and finally realized I couldn’t do it alone (and didn’t know what I was doing). After a lot of research I found wonderfly and Jordan reached out to me and was super proactive with finding a trainer that could help me with my goals! I was paired with Jenna and have been training with her for about 4 months and I’m so happy. I feel healthier, have more energy, my endurance has improved so much, my confidence has gone up in the gym and I go to the gym regularly on my own now. Jenna is amazing, she pushes me and helps make sure I’m doing everything right, she teaches me new things and any questions I have no matter what are answered. I have so much more knowledge now that I never had before, my mindset especially has totally changed for the better. I went from just wanting to improve endurance to wanting to be stronger on top of it. Long story short I think it’s safe to say wonderfly has been a huge part of my health journey that has helped change my life in such a positive way.Samantha LesterSamantha Lester1654869766 ★★★★★ I joined the Wonderfly community in January 2021. I actually went to book my children’s birthday at the arena (which is also way cool) and when I saw they offered athletics I didn’t think twice and signed up. I’m so glad I did. Through competent trainers, a motivating program, and a group of awesome people (at all fitness levels) I have seen major gains. I feel well supported at Wonderfly and know that if I have a question the resources are there. This is a judgement free zone of positive, goal oriented individuals. Traditional gym never worked for me. I would spend more time figuring out my playlist than actually exercising. Here I show up ready to work and the trainers have a dummy proof workout lined up. Leaves little room for excuses. I definitely recommend if you want fitness direction and a supportive community.Chelsea FeeneyChelsea Feeney1651342317 ★★★★★ Wonderfly Athletics is an awesome gym! The set up is great with a stocked weight room and large turf area for bigger group sessions and speed/agility training. The trainers are always so welcoming and truly take time to get to know gymmembers. The atmosphere is very fun and comfortable. There is always some hype up music playing and great conversations in between sets!Hands down favorite gym I’ve been to! 👏🏼👏🏼Teriko HallTeriko Hall1651238730 ★★★★★ JB is The Goat of Fitness, from my very first workout on 3 day free trial, I was hooked!!!

Go see the facility you won’t be disappointed.Stephen HartleyStephen Hartley1643740896 ★★★★★ I'm in my 2nd week there. After I signed up and a start date was establish a start date I didn't show. Later that afternoon Jordan reached out to me to see if everything was okay. That meant the world because it was more than just money. I go to the 6 am class the Jordan modifies workouts to fit your health. He has gone over nutrition and hydration with me. Also checks in on me to see how I'm feeling after workouts. So, if you are looking for a place that cares and are concerned with you health I would highly recommend them.Kendrick LoweryKendrick Lowery1640901424 ★★★★★ This is by far the greatest gym I’ve ever been to!
