Brianna Battles believes athleticism does not end when motherhood begins. Frustrated by the lack of resources and support for pregnant and postpartum athletes, she founded Everyday Battles to bridge the gap. Now, she empowers everyone from Ultimate Fighting Championship (UFC) fighters and Olympians to hobbyists to challenge their perceived fragility, navigate body and identity changes, and pursue a lifetime of athleticism. Battles notes how strength and conditioning coaches are uniquely poised to influence communities and train general populations using a top-down coaching philosophy. Conducting needs analyses, she focuses on their athletic history, predispositions, and how they manage breathing, pressure, and tension during movement. By reverse-engineering a proactive return to performance, she helps clients overcome social media glorification and fearmongering to design an athlete-mom life that serves them. Battles discusses tapping into the “athlete brain” that craves routine and buy-in. Her advice? Get curious, practice brave, and embrace entrepreneurship as another form of progressive overload.
