While most people are hooked into sports and other traditional exercises like football, basketball, weightlifting and gym fitness activities, health and fitness experts promote a more conservative form of fitness activities that are not too strenuous, this is what we call alternative exercises. Based on expert studies, simple warm-up stretching may actually damage some parts of the body such as the muscles, joints and tendons especially if not properly executed. Some people may also experience spine injuries if warm-up exercises are done with improper posture.
