GRIT Fitness is Dallas’ #1 women’s empowerment community! If you’re looking to make friends, shape up, build your self confidence and have a blast, join the #GRITFAM

GRIT was founded by Brittani (Brit) Rettig in January of 2015. This full-body boutique fitness concept is 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. Brit advocates that learning to endure though physical challenges teaches us to persevere through greater life challenges. "We can't always control life's circumstances but we can control how we respond." Known for bringing a fun and welcoming atmosphere to energetic cardio, sculpting, cycling and dance classes, GRIT is somewhere you let your hair down, turn the neon lights up, and dance like nobody’s watching.

At GRIT, Brit has designed and curated a set of 17 original, music-driven group fitness class formats that provide an intense workout and a fun experience. From boxing, to dance cardio to yoga, you can enjoy them all! She's also hand-selected an inspiring team of instructors who each demonstrate the core values of passion, fun, positive energy and perseverance.
