The whole excercise takes about 12 minutes. When the device is turned on, it measures the hardest you can squeeze with your right hand. Then there is a 10 second break, and you squeeze as hard as you can with the left hand. Once those measurements have been taken it is time to start.
When you squeeze at the beginning, it creates a target value where you have to squeeze constantly for 2 minutes. After that you have a 60 second break, and then another 2 minutes with the other hand. This cycle is repeated 2 times.
This is what the screen looks with a brief description of what each item means. (Click to make the images bigger)
If you don't squeeze enough, or squeeze too much, there is a visual warning as well as different audible beeps in case you aren't looking at the device at the time. Below you can see what a perfect squeeze is. It will say hold, and your goal is to hold it there for the whole 2 minutes.
I read online some reviews of people who have arthritis say negative things about the Zona Plus. I can now understand. If you have problems squeezing, then this is not the device for you as a lot of pressure has to be applied. Below is a nice picture of my nice red hand after the first time I used the device.
After each excercise, a score shows up. This score lets you know how well you did at keeping at the target range. With my first try I scored 85 (my wife tried it and scored 99 on her first try). According to the manual anything over 85 is good. The past three times I have scored in the 90's with my high being 97.
That is basically it. 12 minutes a day is more than worth it if this delivers the results I hope it will. My advice to anyone who is trying out this device is to not give up after your first try, things will quickly get better.
One more thing.... my blood pressure today was 128/87.
