EMS workouts are a highly efficient way to target all areas of your body. By engaging up to 98% of your muscles, compared to the 60% typically used in traditional gym workouts, you can burn up to 500 calories in just 20 minutes. These low-impact exercises are designed to minimize stress on your shoulders, back, and knees. In fact, adding just 20 minutes of EMS to your routine is equivalent to a 90-minute high-intensity interval training (HIT) session.
