Bone loss is a common secondary complication of spinal cord injury (SCI), and treatments used to reverse this condition have equivocal effectiveness. The aim of this study is to determine the effect of intense multi-modal training on bone health, body fat, and quality of life in persons with SCI. Participants will complete 6 months of training during which various measures will be obtained at 0, 3, and 6 months. Control subjects are also being recruited to complete testing but not participate in training.
