Medical News Today -- Studies overwhelmingly point to regular physical exercise as the crucial medicine for what ails Americans. Physicians have a hard time convincing even healthy patients to take action, but it’s a much harder sell for those with limited movement caused by physical disabilities. They often lack the self-confidence to begin a physical fitness plan, and it’s easy to understand why. They face transportation obstacles to visit an exercise facility. If they can get to the facility, accessing the building and equipment is often difficult or impossible, and fees are often high, says Dr. Zibin Guo, a medical anthropologist in The University of Tennessee at Chattanooga Department of Sociology, Anthropology, and Geography. He says appropriate and interesting exercise is often not available to this group.
