“Becky” Rebecca Sefscik, a coach at Crossfit The Tracks (Erlanger, KY) and US military veteran, created this workout herself in 2012. Becky Sefscik sadly took her own life on August 31, 2015 after battling PTSD. Her box's website posted that the workout "was tough, just like Becky...She was one of our favorite trainers, best friends and she's missed every day. She was not only an amazing coach, but she was one of the strongest people we all knew, mentally and physically."
