We report the case of a 34 year-old man who developed exercise-induced rhabdomyolysis after unaccustomed high-intensity exercise. Subclinical rhabdomyolysis is common after heavy exercise, yet it is uncommon for patients to seek medical advice. The presentation is variable and despite potentially life-threatening complications the diagnosis may be easily missed by patients and healthcare professionals. A high-index of suspicion is critical to avoid missing the diagnosis. We summarise the current knowledge, clinical course, complications and management of exercise-induced rhabdomyolysis.
