Did some paddle boarding in Hawaii. I am fat and very whitey so if you want to imagine me on a board here is a similar image.
My sister in law a fabulous Pilates instructor has been playing with the board for awhile and is impressed with how the board facilitates the use of the core.
What seemed to strike me more is my feeling that my left and right side use is not symmetrical and I have a role for each in my learned everyday tasks. It makes it hard for me to balance on the board as I tend to use the left for stance and stabilization and the right free for movement and power. That and being somewhat beluga and marshmellow like.
