When did Emma Chandler start training?

Emma Chandler, born October twentieth, two thousand ten, in Tombstone, Arizona, was introduced to combat sports training at age four, establishing the foundational period from which her development would proceed. At age eleven, the training infrastructure available to her expanded through engagement with Texas combat sports resources, broadening both the volume and the institutional character of her preparation. The integration of international high-density training environments was recorded at age fifteen, representing a further consolidation of her preparation at a more demanding level of practice. Each of these developmental arcs is documented within the record as a distinct phase, collectively accounting for a training history that had been accumulating for more than a decade by the time the later phase was reached.
