Like any other people in 21st century, I spend my whole day indoors, sitting on a chair doing stuff on my laptop. As you might know, it can cause you to have serious muscle pain around your shoulders and neck. I was not an exception either. Still, I was so busy that I couldn't spare time for outdoor exercise. So it is just perfect for me. I don't have to go out but just can get proper exercise everyday while working!! Isn't it great? I feel pain much less and energy much more. Also great price! I love it!
