Cover Story: The overtraining syndrome is a complex and multifactorial condition. A lack of individualised testing protocols and gold standard markers, combined with multidimensional, individual symptoms, makes both identification and diagnosis difficult. To date, no study has investigated the complex nature of overtraining and/or the overtraining syndrome from the perspective of the high-performance strength coach; therefore, the aim of this study was to explore this subject qualitatively and to provide a new way of understanding such concepts in practice.
