CoPo Rivas Arriaga

CoPo is a CrossFit coach, personal trainer, and nutrition coach who is passionate about helping people feel strong, capable, and confident in their bodies. After joining CrossFit Longmont in 2017 as a mom looking to reconnect with her strength, she quickly fell in love with the process—and the community—which inspired her to turn that passion into a coaching career.

CoPo brings a supportive, down-to-earth approach to coaching, meeting clients where they are and helping them build sustainable habits that last. She believes fitness should empower every part of life, both inside and outside the gym. Her certifications include CrossFit Level 2 (L2), Precision Nutrition Level 1 (PN1), NASM Corrective Exercise, and USA Weightlifting Level 1 (USAW L1).
