Bests & Worsts Reviews from Amazon

I have been a student of fitness for MANY years. I have been active in weightlifting and competitive brazilian jiu jitsu, for MANY years. I have NEVER bought a "device" for exercise. There, that should put my following review into some perspective. After a severe injury I was unable to workout or train for quite some time. During that period work increased, I bought my first house, and life got away from me as did my physical health. Getting back in the gym at the age of 40, overweight, and the weakest I have ever been was something I have been struggling with. When I saw this device for some reason it caught my attention. With a ruptured lower lumbar disc, core strength is the key to my daily health and ability to function. That area has been lacking lately and I have been suffering as a result, but I HATE core work, and I HATE planking even though those two things will improve my quality of life. I got the plankster and fell in love with it on the first session. It says to do 3 minutes a day but I could barely do 45 seconds. No worries, I couldnt wait to get on again because it was SO MUCH FUN!! Working my core has never been so mentally engaging. I love this thing and I fully endorse its effectiveness in terms of both workout, AND motivation. I would recommend it to ANYBODY and I will never NOT have one of these in my home.
