Zona Plus is a handheld, software-controlled device that uses calibrated isometric handgrip exercises (squeezing a grip) for about 12 minutes daily to improve cardiovascular fitness and naturally lower blood pressure by enhancing artery flexibility and function, acting as a complementary tool for blood pressure management for those who struggle with traditional exercise. Each session calibrates to your strength, providing real-time feedback to help lower blood pressure and improve heart health over time, often reducing the need for medication under doctor supervision.
