I’ve been going to F3 for over 5 years and have never done the same workout. Always challenging and fun. Loving the new heated classes too!
DeAnn B.
This place is about as good as it gets with classes, schedule, instructors, location, facilities, culture, etc.....The workouts are very challenging and each instructor seems to know how hard to push in each of the different classes.
Scott Z.
They are the hardest, most challenging workouts that are actually fun. The community and teachers are amazing.
Jennifer B.
Fun, challenging, never the same!  Trainers are encouraging and fun,  Great music, too.

Always challenging. Great atmosphere. Trainers are always positive. The facility is large enough with excellent and varied equipment to allow for challenging classes and personal training sessions to happen simultaneously
Jeffrey M.
10/10 Best trainers and group classes I have ever worked with. I get great results from a variety of classes and times that work with MY schedule not THEIRS!! The equipment is continually upgraded and maintained. The trainers keep the classes consistent but change enough to keep it interesting and fun and ALWAYS challenging. The other clients are supportive and friendly which really helps motivate you through your workout.

The people! We are all here to get in a good sweat and we all have fun while we are doing it. I have never been so excited to wake up at 5am for a workout. Every time I leave I look forward to going back.

Good instructors and energy. Motivating.
Susan C.
I have only attended one class, Define, as I just started my 30 day membership. I enjoyed the class and Molly our instructor very much. The day I registered I appreciated being given a full tour of the facility. Everyone has been very welcoming and I'm looking forward to my intro assessment and taking a variety of classes.
Katherine B.
F3 On the Fly is by far the best one stop shop for online workouts and nutrition. Other programs are too rigid and seem to miss the mark on being FUN! Thanks F3, you nailed it!
Sarah R.
Fit Flex Fly is the best gym in Indianapolis!
Nicole N.

Meagan L.
Lance is great, he is challenging but makes it fun
Catherine C.
The entire F3 training staff is second to none, they are extremely qualified and committed to making sure the classes are challenging and fun at the same time. F3 does a great job of pushing me beyond my comfort zone in order to maximize my workouts. I enjoy the up tempo pace, variation of classes, addition of new exercises, the quality of trainers and feed off the energy of others in the class.
Randy C.
The unpredictability and constant movement during workouts makes them fly by.
Ryan R.
The workouts are no joke, but I lost inches and learned how to eat without the stress and guilt I was so accustomed to.
Megan M.
The classes are challenging and always evolving. However, challenging classes can be found at a number of places. What I like most about F3 is the culture. The staff makes the effort to know clients by name, they encourage clients and foster a sense of community.
Shana is an amazing ambassador for F3. I see her most often when I arrive and she never fails to set a positive tone!
Natalie W.
I find each workout to be well thought out, and be of high quality. I always leave feeling like I have improved my fitness.
Oliver S.
Great intensity and the trainers constantly change it up so that they don't get boring and it challenges you in new ways.
Paul K.
I have had great results with decreased body fat and better weight control. I love how hard I am pushed but it is fun and enjoyable and always different. I look forward to working out & hate to miss.
Teresa K.
I really love the instructors in all the time and effort they put into making our workouts amazing every day.
There is nothing else like it in the city!!!

There is constant cardio along with strength in every workout. The energy!! Great variety of classes and it's never boring. Love this place.
Aleasha S.
Cannot say enough good things about the last 30 days. I've finally found my groove and feel like I've created some good habits. I loved the meal planning and grocery shopping guide. Simplified my life.
Emily F.
Variety, intensity, music
Dan M.
Challenging classes and a lot of variety. Great energy and fantastic instructors.
Megan Z.
I love the every work out is different, that I have the ability to choose what class/type of workout I want to do that day and that the trainers are knowledgable and fun.
Jennifer S.
Fun and unique!
Katie H.
I don't come often, only when I am in town from Chicago with my brother, but I love how there is so much variety in the workout. I love the stations and TRX bands the best. I have tried to convince my Indy friends to come. But I also think you have to be somewhat in shape to come to a class. It could be a bit overwhelming for the first time because of how fit everyone is there. Oh I like the music too!
Julia N.
Challenging and they are different every time
Benita T.
High pace and high energy
Emma M.
Workouts are always different. Instructors do a great job of keeping the workouts fresh and interesting. Instructors also have been very aware to modify my workouts in the interest of my recovery from knee surgery.
Duke H.
I love the variety of workouts I can get at one location. The classes are fun and always different. F3 really strives to meet the needs of everyone that walks through the door.
Abby S.
The variety of workout, times available, and toughness
Lori F.
Always integrating new and different exercises into the workouts
Drew N.
The atmosphere is friendly yet serious about fitness! Trainers are top notch and they truly care about their clients experience & fitness! Love that every class is different day to day and week to week ! It never gets easy and that's a true sign of a great gym:)
Jamey K.
I love how challenging they are and how they're never the same. I never get bored and always leave extremely sweaty!
Kasidee K.
Well paced, positive attitude of instructors, allowing me to go at my own pace when necessary, group keeps me going

One request: Bring back Nicole's 530 Thursday compound conditioning class

Haven't had enough to comment specifically on all the classes, but so far what I've experienced is targeted specifically to me and it is fun
