STEP AND GO: A Study of Technology-based Exercise Promotion

"Investigators will provide participants with a smartphone and required accessories (gift card for downloading the game application and music, headphones, armband). The game, Zombies, Run! encourages walking/jogging by playing music interspersed with a continuous narrative. Periodic zombie chases encourage brief interval training. Participants will set goals to increase their activity and receive weekly brief counseling phone calls to provide feedback."
