Lindy's athletic background includes twice being named All-State in soccer in her native Kentucky in high school before playing two years of soccer at Dayton University. She also spent eight years as a part of a competitive jump rope team. She is the current middleweight women’s champion of Rush Club, a head-to-head fitness competition. While executing a back squat in 2011, Barber felt something snap. She had broken her L5 vertebra and was also diagnosed with three conditions she never knew she had: scoliosis, spina bifida and spondylolisthesis. Despite being told by doctors she would have to lead a more sedentary life, Barber made a comeback and returned to training. She qualified for the CrossFit Games in 2013, where she finished 28th. She again qualified for the Games in 2015.
