    Athlete Spotlight

    Margaret H, 1 Year In!

    After training at CrossFit Roots for 1 year, Margaret dishes on a TON of profound and valuable information that would help any athlete grow and develop. Tune in to learn about how Margaret wanted to have fitness goals based on fitness, not aesthetics, how she made the mental shift from exercise to training, why scaling is good, and how to fail upwards.
