In addition to replacing muscle, reducing fat and revving up metabolic rate, research reveals many health-related reasons for performing regular strength exercise. These include lower resting blood pressure, better blood lipid levels, greater glucose usage, increased bone mineral density, less low-back pain, reduced arthritic discomfort, faster gastrointestinal transit and improved psychological profiles.
ufts University recently completed a strength-training program with older men and women with moderate to severe knee osteoarthritis. The results of this sixteen-week program showed that strength training decreased pain by 43%, increased muscle strength and general physical performance, improved the clinical signs and symptoms of the disease, and decreased disability.
