Plank 360 Stand Up Plank Device
I am Dr. Sheets who invented the plank360. I highly recommend the device to strengthen your core without having to get down on the floor. When you strengthen your core, it will help to stabilize your back so that you will not have any back issues in the future. Hundreds of my patients have experienced great results with the plank360. When you purchase it please let me know how much you enjoyed the results.
