The Training Box-CrossFit® TTB: Opinions

Fantastic experience: If you're looking for a place to work out at a level that suits your specific needs and abilities, The Training Box is an excellent choice. Cooper and the other coaches take pride in understanding what each individual can do without hurting themselves. The sessions can be tough enough to make you feel like you just did something worthwhile but not so difficult you need to go to the emergency room. Very supportive group and always fun.
Thanks so much Tom! Trust us so much you invited your wife!
Fantastic experience: Very excellent and talented trainers.
Thanks for the kind words Scott!
Fantastic experience: Not gonna lie. There was a creepy old guy with a marines hat on wierdly asking what some of us buff young guys did for fun but besides that.. gym is awesome especially for calisthenics!

Thanks so much Gabriel! You have come so far.. We love you and the family!
Fantastic experience: Hi folks….TTB is tucked away in Roswell; however, once you find it you will be glad you did. I’ve been working with Collin and he has helped me in a few weeks get smarter and stronger about my own fitness. He listened to my goals and has provided excellent professional advice about getting stronger for running, better with endurance and wiser about fitness in general. Come and give it a try. I’m glad I did. Your body and your health are worth the investment!
Thanks so much for the kind words Joanne! We are also glad you found us
Fantastic experience: Go to TTB….seriously, I drive an hour each weekday to train there, and it’s worth every minute. After going to all sorts of gyms, I found what I was looking for….a culture that provides support, fun, encouragement, education and positive vibes!!! No need to feel intimidated when I walk into the box each day! I have made amazing progress and learned so much! I strongly recommend The Training Box-Crossfit! And I ❤️my fit family there! Go!
Fantastic experience: joined The Training Box having never really done any kind of formal lifting or strength training. So I started with an 'essentials class'. I really think the essentials class is critical to making sure your going to use proper forum and technique when lifting. Working one on one with an instructor that first month really helped. The gym is very welcoming and the overall community and classes are very welcoming to newcomers and experienced gym rats.
Thanks so much Zane! You are killing it, and we are fortunate both you and Anna have found us!
Fantastic experience: Are you looking for CrossFit without the injuries? This is the place for you! The programming is strategic and thoughtful. You can rest assured knowing your body will never get overworked. The classes are small group focused, allowing the coaches to watch and monitor you for form. You’ll never get lost in the shuffle here. There is an attention to detail I have not seen at other gyms. The owner (Cooper) knows each persons ability. He knows what each and every member can lift. Your progress will be focused and rapid. There is an amazing nutritional coaching program. Healthy eating is the focus (not fad diets)! I have learned so much about how to eat more nutritionally complete meals (hello protein!). Finally, the community. When I left college, I was searching for a community. This is the kindest and most diverse gym I have ever been too. Everyone encourages and lifts each other up. Events are regularly scheduled by the gym to keep engagement high. And when there isn’t one? Members are regularly hanging out and are creating their own. I honestly recommend this place. The benefits greatly and you won’t regret it.
So sweet Anna! Thank you. We are blessed that you’ve found us!
Fantastic experience: I work out with Cooper Sellers. He is the owner & an excellent personal trainer. I've worked with him for 14yrs. Over the years I've had occasions to meet several of the other trainers working there. They are all highly competent, very professional as well as being really nice people. I strongly recommend the Training Box to anyone who is looking for a quality professional gym!!
Fantastic experience: Great trainers.. awesome place with brand new equipment. NEEDED TO SAY IT - Sep/2023 I have been attending this gym for 7 years, and today they exceed my expectations. I brought my mom, who is 70 years old, From the very first moment she came in, the coach welcomed her that made her feel good and respected. ⭐⭐⭐⭐⭐ Right before the workout the coach took time to explain every single modification and reps she will be doing, based on her capacity and during the workout, he was next to her, assisting and making sure she was physically ok, making sure her transition from step ups, squat Trust, bike, KB carry were done in a safety way.. ⭐⭐⭐⭐⭐ So, if you are looking for a place where they will be patient with your fitness journey, where you are welcome, everyone is friendly, and you get some laughs, support and good vibe. This is the place
Thank you Elyn!
Fantastic experience: The Training Box has completely turned my life around!! When I decided to lose weight I turned to the internet for choices and such. Max from the gym contacted me and we began to talk about my goals. Being 61, retired and still above my weight goal I still had many questions. It wasn’t until later in our conversation over the phone I discovered he was in Rowell, GA and I’m in Tennessee!!! Just a little too far to drive a couple of times a week!! But after talking with him about virtual training I thought ok I’ll try it but this will not work. Well guess who nearly lost out on a life changing opportunity ?? Since May of 2020, Max and I have worked out five days a week. I could not be any better if I was at the gym physically. Max cares about every move I make and he never takes his eyes off me. Whenever I think I’ll catch him he is still there. And what a motivational coach. Wish I had the words to say how he gets me going and how he gets me over that lift I didn’t think I could make once more. So if you have read this and was thinking is this for me the answer is yes and yes!!! Doesn’t matter if you live in Rowell or California this gym can help you. I went from someone who was mediocre to now with Max’s training plan to compete soon in Physique competition. So reach out to them and make that call or visit. It will change your life!! It has changed mine forever and for that I’m forever grateful
Thank you so much for the review Craig! We appreciate and love working with you. We are grateful for the opportunity to have met you! Here’s to 2021
Fantastic experience: Max has been an amazing personal trainer! He listens to your needs and adjusts exercises accordingly, I have enjoyed all sessions with him so far. The gym has all the equipment you might need for every exercise. I would definitely recommend TrainingBox.
Thank you so much! We love working with you
Fantastic experience: I started virtual training with Max Bohling back in August 2020, during the midst of the pandemic. I can honestly say that he has been the best coach and motivator I have ever had. He has been extremely influential in helping me reach my goals. I couldn't ask for a better coach.
Fantastic experience: Just want to say “the people here are amazing” isn’t a just sales pitch. I feel super supported, loved and welcomed to the family ❤️
Fantastic experience: My wife and I tried virtual personal training with Max. We loved it so much that we signed up for a year! And hope to keep it going beyond that. It’s been awesome because he explains what we’re workin on and towards and answers all my question (I ask a lot)! He’s also been really patient as my wife has medical limitations. The education had been great, and the results have been even better.
Fantastic experience: I worked with Renee at The Training Box! She has helped me make great progress towards my fitness goals! Always a nice and friendly atmosphere here!
Fantastic experience: THE best gym, fitness program and coaches I have encountered. My personal trainer, Max Bohling, has been instrumental in helping me design a program specific to my needs and goals. Being a senior (66 years old) I was apprehensive about returning to a gym, however, Max, all The Training Box staff and it's facilities have made it fun and something to look forward to! Thank you so very much!
Fantastic experience: Positive: Communication , Professionalism , Quality Just want to say “the people here are amazing” isn’t a just sales pitch. I feel super supported, loved and welcomed to the family ❤️
Fantastic experience: TTB is a very welcoming gym with members who have been with the owner for over a decade. The workouts are consistently challenging and scaled to your abilities with a push to level up when coach feels you’re ready. The staff is very knowledgeable with a focus on total health of mind and body. There are scheduled open classes every day (Sunday’s off). Personal training sessions are excellent and worth every penny. Coach also offers fitness/food challenges, annual training events, out of gym activities, etc. to keep members engaged and focused on goals. People of all ages and fitness levels are welcome. Show up! Move! Improve! You‘ll be so glad you joined this awesome fitness family!
Fantastic experience: Awesome place to workout!
Fantastic experience: This is the best place I have ever been to. I have been taking medication for anxiety and depression for over 1 year. At first the drugs worked, but then the depressive states became worse to the point of having suicidal thoughts. My neurologist recommended me to exercise daily and a friend took me to TTB. Love this place from the first routine. All coaches are well prepared, attentive, they know the capacity of each person as if it like personal training. You feel like they take care of you. It is not just a place to exercise, it is like a family with a harmonious atmosphere, very pleasant where each takes care of the other. I feel super good and can sleep without medication. This is my therapy and it is the best mind and body medicine I have ever been able to take. Thanks Cooper and thanks Elyn for bringing me here.
We love working with you Marilyn! We love the whole family! Thank you for your story and being so open so that hopefully this can help others.
Fantastic experience: Found this place while looking for a calisthenics personal trainer. Very happy with my decision to choose TTB. Friendly staff and great environment! A++!
Thanks Joshua! We love working with you in helping you crush your goals.
Fantastic experience: In the last two months, this gym and the people who work there have totally changed my life. I have received nothing but total support and acceptance, which was something I was extremely nervous about being someone who has never stepped into any gym besides a Planet Fitness. My trainer Renee has walked with me every step of the way, always there for me to text with any questions. I have also recently suffered a back injury to which she has been nothing less than accommodating about working around it with me. As well as the gym is kept extremely clean, which is something much appreciated during coming out of a pandemic. All in all, I would 100% recommend this gym to anyone and everyone no matter your age or fitness level.
Thank you so much Emilie! We are happy that you are a part of the TTB community and are excited to continue to help you along your fitness journey.
Fantastic experience: LOVE LOVE LOVE my TTB family! ALL levels of fitness are welcome here. Awesome community and comradery. The coaches are very knowledgeable, patient, and encouraging. You will not be sorry that you came!
Thanks Brenda! We love you
Fantastic experience: Son buenos y profesionales
