About Keira

Chaotic Good Fitness empowers people to improve themselves through movement and habit changes. We help clients feel confident in their own bodies and set them up for success in their health and aesthetic goals.


Chaotic Good Fitness is the creation of Keira Harbison, a lifelong nerd and educator who discovered weightlifting in college as a way to lose weight. They live in Atlanta, GA with their partner and pupper. When not picking up heavy things and putting them back down, they are playing board games, watching Doctor Who, or reading. They have been an ACSM certified personal trainer since 2018 and are ready to get you where you want to be!

My favorite client story

I was training a couple together and I like to give them partner workouts. They were doing a particular plank variation and started playing rock paper scissors. It makes me happy to see people enjoying themselves while working with me AND it added a nice bit of friendly competition to the workout.

My favorite exercise

It changes regularly, but right now, bear crawls.

My favorite quote

There is a particular quote from Don Quijote that I love that boils down to "I know who I am and I know that I can be whoever I want."

My training philosophy

Be adaptable, be compassionate, but get the work done

My training experience

Mostly focused on strength training and weight lifting with some mobility and yoga intermixed. I try to be as holistic as I can.

I've been working with clients since 2017.

Keira has been a fantastic trainer. They have kept me on a good middle ground between pushing myself but not over doing it. They also talked with me beforehand to make sure my goals were reachable and practical. The program has been great thus far


An amazing personal trainer! Did a super job making a customized workout plan that met my needs and was the right mix of simple yet challenging. Gives very realistic expectations and emphasizes heavily on proper form and safety for the best and most effective exercises! They are always easy to approach and open to questions/concerns to help you on your fitness journey! 11/10 def recommend

Keira is amazing. My greatest challenge to getting physically fit has always been a lack of knowledge. Honestly, I had no clue what to do. They worked with me, without judgement. I asked for basic exercises that I could do on my own and they taught me some. Like when i saw taught I mean, teaching me the correct way to do the exercise and how to stay safe doing then. I'm definitely going back to them for more lessons when I'm ready to start up again.

Keira and I met through the FYT app/website and I am so happy I found her! We've been training for a few months and she provides such an empowering and supportive environment to train in! She is extremely flexible and go with the flow, meeting me at my home gym and training me there. We celebrate little victories and continue to push for more progress! She's knowledgeable and I never feel judged. She's been super fun to work with!! Strong recommendation!


Keira really helped me achieve my goals! I was over 220 pounds after giving birth and felt completely helpless. Keira was so sweet and understanding and made food recommendations and a meal plan that really worked for me. She took into consideration my exercise preferences and developed a plan I knew I could stick to. Two years later, I’m 50 pounds lighter ??
