Abstract
dangerous flexibility program consists of exercises that place unusual and unnecessary stretch and/or force on muscles, joints, and nerves. Many so-called stretching exercises have the potential to do more harm than good. No one should do an exercise that has the potential to result in degenerative changes in joints and nerves over time. Dangerous flexibility exercises that involve placing the head and neck (such as the plough and shoulder stand bicycling), knees (e.g., the deep knee bends and quadriceps stretch), and low back in an awkward or questionable position should be avoided. It is unfortunate that so little credible information is available to athletes, coaches, and individuals interested in flexibility training. The content in this chapter should help lay a solid foundation for thinking straight about which flexibility exercises should be avoided.
