I read and purchased a book by Dr. Suidobashi several years ago. Pressure pants: By applying pressure, you can train efficiently in a short amount of time. There are no instructions or box, so please research how to use them online. They will be shipped in bubble wrap. Part of the belt loop (see photo) is peeling off, but it is sewn securely, so I don't think there will be any problems, but please refrain from purchasing if you are concerned. #Katz #PressureTraining #Exercise #Health #SportsExercise
