Moskovitz, Dustin: The Back Buddy by the Body Back Company is my favorite purchase from the past five years, bar none. Most basically, it allows you to administer self-massage anywhere on your back with the full leverage of two hands, but I’ve also really gotten to know and appreciate all the little knobs and others features over the years. I’ve even learned how to manipulate parts of my skeletal structure (. self-chiropracty) and incorporate it into my yoga practice. It only costs $30, so I have purchased several: one for the living room, one for my desk at the office, and a collapsible version for traveling (though I do bring the full-size one if I’m checking a roller bag). With 4,500 reviews and a -star average review on Amazon, I’m far from alone in my appreciation of this product.
