Julia Halberstam

Julia began CrossFit in 2018 after years of being active and learning how to adapt movement to her body. Born in Russia and adopted at a young age into a family of ten, she grew up surrounded by resilience, adaptability, and a lot of determination. As an upper-limb athlete, Julia has spent years learning how to train through challenges, push her limits, and embrace what her body can do. 

After years of training, she stepped into adaptive competition and has since competed at the highest level of the sport as a two-time CrossFit Games athlete, placing second in 2025. Her experience as a Games competitor shapes how she coaches, with an emphasis on effort, smart training, and continual progress. 

At Blackbird CrossFit, you'll see Julia in Group Classes and CrossFit Kids! She loves helping athletes build confidence, move well, and discover they are capable of more than they expect. Outside of the gym, Julia is continuing her education in healthcare while pursuing her coaching career. Whether she’s working with kids, new members, or competitive athletes, her goal is to create an environment that is supportive, challenging, and fun, where people leave feeling stronger than when they walked in.
