Any fitness method is not perfect and has defects. Routine training can also lead to various problems. The common causes of rhabdomyolysis syndrome are exercise, muscle squeezing, heatstroke, drugs, poisoning, infection and so on. For example, exercise-induced rhabdomyolysis syndrome can occur in young adults who participate in excessive physical exercise and military training in hot or humid high temperature environment. In the process of EMS fitness, EMS certified coaches will judge whether the intensity is appropriate according to RPE (self-perception threshold table) and members' sports performance, and strictly control the training duration, which is generally 20 minutes. If you go to that professional EMS studio, you will replenish water and electrolyte for your members before, during and after training.
