Product Description
An entire isometric exercise session in just 12 minutes
What is Isometric exercise and why do I need it?
Isometric is the Latin word literally meaning equal measurement. As this relates to exercise, isometric exercise is the type of muscle contraction in which the muscle is tensed and working, but not actively shortening or lengthening (with no joint movement). Comparatively, concentric contractions are the type of contractions in which a muscle, or muscle group, is shortening (such as the abdominal muscles during a sit-up) and eccentric contractions are the type of contractions in which a muscle, or muscle group, is lengthening (such as in the relaxation of the sit-up motion). While all forms of exercise provide benefits, isometric exercise is unique in the benefits it provides. Isometric exercise is also ideal for people who suffer from chronic joint pain.
Benefits of Isometric Exercise
- Increased Cardiovascular Health
- Constant Muscle Tension
- Increased Nitric Oxide

Initial CalibrationAt the start of each session, the Zona Plus measures the user’s Maximum Voluntary Contraction (MVC) to calculate the ideal workout for today. |
Guided ExerciseUsing a series of visual and auditory cues, the Zona Plus guides the user through the predetermined exercise, providing real-time feedback along the way. |
See the ResultsAfter each session, the Zona Plus provides feedback on the user’s performance during the exercise session and stores this data for over a year. |
Our story actually began in the US military, as strange as that might seem. The research was first conducted while trying to solve a completely different problem for the U.S. Air Force. The Backstory: Upon deployment of its first F-16 fighter jets, the Air Force found that many of its fighter pilots were experiencing incidents of g-force blackout: a condition that causes temporary vision loss. This type of aircraft turns very quickly, putting greater g-force on the pilot, and thus putting him in danger. To find a solution, the Air Force commissioned Dr. Ronald L. Wiley, a respected cardiopulmonary physiologist, to research the problem and, hopefully, find a solution. Multiple experiments were conducted, and countless hypotheses were disproved, but one particular experiment yielded some unexpected data. As part of one of his experiments, Dr. Wiley had pilots grab a steel rod as hard as they could while experiencing g-force under flight conditions.
While poring over the subsequent data, Dr. Wiley became intrigued by the health histories of two particular pilots, each who were considered pre-hypertensive prior to his battery of experiments, yet were back to normal levels at the completion of the experiments. Believing there must have been a link somewhere in his research, he made it his life’s goal to find the link. After years of research, Dr. Wiley drew a correlation between the steel rod and the reduction he had measured. The grip, he determined, simulated an isometric exercise. Over time, and after much trial and error, Dr. Wiley developed the computer-controlled handgrip exercise device that we now affectionately call the Zona Plus! The Zona Plus uses biofeedback to design personalized exercise sessions, customized for each user, by calibrating to what we call maximum voluntary contraction. Each session is unique. Each session is effective. And each session is conducted with the user in mind.

I Had To Stop Using It
Even though the listing describes exactly what the Zona Plus does and how the exercises work, the actual experience of it was quite lacking. Its limited scope and poor 64-bit like graphics, just aren’t acceptable to me at this price point. The “exercises” are monotonous and it’s not as easy as you might think to just stare at a screen that’s counting down for 12 minutes. Extra visuals or even a small video would have helped at staying focused. Barring that, then more sound cues would have been effective.The Zona will show you limited information after each session, but you can’t go back and view that data on the device itself. You have to download software onto a pc if you want to track your progress. There’s not even a phone app for this product, so you’re stuck to pc use. Given that all you do is sit down and squeeze it, it’s actually a solidly made device. The heft is decent, it has a good grip width and the silicone areas keep it from slipping. The battery life is okay, losing only 50 percent after 7 daily sessions.The instructions say to try this for at least 6 to 8 weeks to see results. Unfortunately, it’s causing me some problems, so after only 8 days, I’m going to have to stop using it. I have a weak wrist on one hand and poor hand strength in the other. This device is supposed to calibrate for any issues and adapt the sessions to accommodate you. Instead, using this has exacerbated my ailments. My Zona score declined from an initial 97 to a 92 and my systolic pressure increased 11 points.Frankly, my wrists feel like they are on fire and my palms are tender. I type constantly so it’s not like I can just rest my hands for hours on end or keep ice packs on my wrists each day. I obviously can’t speak to what benefits this device may offer, but even if it eventually works on lowering blood pressure, I would still feel salty about its graphics and overall functionality.
