GRIT Fitness is more than just a workout — it’s a vibrant community of women who celebrate strength, inclusivity, and empowerment. We ditch the treadmills, the scales, and those intimidating weight machines. Forget about counting down the seconds on the stairmaster — here, we’re all about progress, not punishment. With an energetic instructor guiding you, you'll push yourself further than you ever could alone. And the best part? You’ve got the GRITFAM, a whole squad of amazing women, beside you, working through the burn together, motivating each other to keep going. By the end of your session, you’ll walk out feeling powerful, confident, and ready to take on anything. That’s the GRITFAM way — strong, supportive, and unstoppable!

Our Founding Story​

BRIT RETTIG WOLD, GRIT FITNESS FOUNDER

Brittani (Brit) Rettig Wold founded GRIT Fitness in 2015, an empowering fitness concept based on her belief that mental grit, or “passion and perseverance for long-term goals” is the key to both fitness success and to living our best lives.  At that time, she was a 30 year old single girl with a dream and a $30K nest egg.  But with a lot of GRIT, she launched and grew GRIT Fitness from 1 tiny studio, to multiple locations, a team of over 50 members and Dallas' #1 women's fitness community.
​
Brit advocates that learning to endure though physical fitness challenges teaches us to persevere through greater life challenges.  "We can't always control life's circumstances but we can always control how we respond - we are stronger than our circumstances."

​She earned her undergraduate degree from Cornell University where she was captain of the women’s varsity basketball team and holds an MBA from Harvard Business School. She’s also a graduate of the Dallas Regional Chamber’s Leadership Dallas Class of 2020. Brit is now a proud wife and mom of 3 beautiful kiddos!
