Exercise Program (TEAM Me) for the Improvement of Movement and Mobility in Pediatric and Adolescent and Young Adult Patients With Cancer Undergoing a Blood Stem Cell Transplant

This clinical trial studies how well an exercise program (Totally Excited About Moving, Mobility, and Exercise \[TEAM Me\]) affects the exercise and dietary habits of pediatric and adolescents and young adults with cancer undergoing a blood stem cell transplant. TEAM Me is an exercise program that reinforces behavior, such as walking and other activities, using "tokens" (i.e. stickers) that can be redeemed for rewards. Participating in the exercise program may result in increased physical fitness, physical activity level, quality of life, and function in pediatric and adolescents and young adult patients with cancer.
