Title: OW!
Review: I bought this from a different vendor and started working out with it immediately, interspersing it with my usual cardio workouts. I usually lift weights, have no prior injuries, and consider myself in pretty good shape as well as pretty used to working out and using proper form (I played a college sport, etc.). After a couple days of using this product my neck and shoulders started spasming and were so stiff that I could barely move them regularly. It was clearly not from the amount of weight since i am used to using much heavier (free weights included). Perhaps I was doing the exercises incorrectly, but that seems like a real risk with a video like this.
Is this product review negative?
