How many times should I train with EMS per week?

For healthy individuals in recreational or fitness settings, the following general guidelines are useful:

Muscle building / performance programs: approx. 2-3 sessions per week per muscle group

Light activation / recovery: gentle programs can typically be used more frequently

Important: Start with lower intensity and reduced frequency, then gradually increase over time. Follow the recommendations in the user manual, and if in doubt, ask a physiotherapist or doctor to help you create a suitable plan.
