Goji Play Exercise Games transform the dreaded cardio workout into playtime by transferring your cardio movements into games on your iPad or iPhone. The game kit includes an activity sensor that you attach to your cardio equipment (treadmills, bikes, elliptical trainers, etc.). You can monitor your progress towards exercise goals in real time during the workout, and the wireless game controllers help you play games that make use of your workout motion. You can choose from a variety of free games and apps that incorporate the exercise motion in some way. Goji Play can save personalized settings for each member of the family, so you don’t need to fiddle with it every time to set it up as per your exercise goals.
