Players are led by a virtual personal fitness coach named Maya (voiced by Yumi Lee, who is also credited for workout design and modeling). Prior to the first workout, players must complete a fitness assessment. Players are asked to record their resting heart rates, then, following two minutes of jumping jacks, are asked to record their heart rates again. This data is used to approximate the relative intensity of the physical activity of completing that set of jumping jacks. This is then used to determine what types of exercises Maya will ask players to complete during their exercise routines. The fitness assessment also records players' self-reported weight and evaluates strength and flexibility.
