Squash demands speed, strength, and control at the edge of human range — but still suffers from a massive stigma around heavy lifting and underuse of strength and conditioning. Brigita Roemer is leading the shift as Director of Strength and Conditioning for U.S. Squash, where she oversees all off-court physical development. After suffering a devastating injury as a track and field athlete, she discovered strength and conditioning when a biomechanics team “put [her] back together,” setting her on a linear path in the profession. Assigned to a sport she had never heard of before, Roemer began by emphasizing injury risk reduction, full range of motion, and “strength at length” to meet squash’s extreme movement and deceleration demands. With frequent connective tissue injuries like sprains and strains, athlete availability remains a top concern. By prioritizing continuing education and building relationships, Roemer has helped U.S. Squash make history — on the path to LA 2028.
