The player is led by a virtual personal fitness coach named Maya. Prior to the first workout, a player must complete a fitness assessment—the player is asked to record her resting heart rate, then, following 2 minutes of jumping jacks, is asked to record her heart rate 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 the player to complete during her exercise routine. The fitness assessment also records the player's self-reported weight and evaluates strength and flexibility. Core strength is measured by the amount of sit-ups the player can complete; lower-body strength is measured by the number of squats the player can complete, and upper strength is measured by the number of push-ups the player can complete. Flexibility is measured on a 1-7 scale by how far the player can reach forward when seated with the legs stretched out in front with feet flexed. On every 10th workout, the player will repeat this fitness evaluation as a Physical Challenge. This results in a dynamic workout program that changes with the player's physical fitness level and ability. Based on the results of each Physical Challenge, Maya will suggest one of 5 areas a player can choose to emphasize in—Weight Loss, Cardio, Upper Strength, Core Strength, and Lower Strength. In addition to this, Maya will also suggest an emphasis for each workout a player initiates. In addition to these workout options, the player can choose to do Yoga by selecting the Meditation Garden. Once a workout is selected, the player can choose the duration of her workout—15 minutes, 30 minutes, 45 minutes, or 60 minutes. The duration is a rough estimate, with the workouts often being a few minutes longer due to additional time spent warming up and stretching. The player can then choose a virtual environment to work out in as well as what genre of background music to listen to—only a few environments and music genres are available at first, but, as the player keeps consistent with her schedule, more are unlocked. The game includes over 500 types of exercises, although some exercises with variable repetitions are counted as separate in this tally. Furthermore, if the player owns an exercise ball, hand weights, an exercise step, or a heart rate monitor, Maya can incorporate these into the program. At certain sections of the routine, Maya will stop to ask how the player is doing; the player's selection of one of three replies will affect whether the program strengthens, weakens, or leaves the current regimen as it is.
Development
In a 2006 fitness promotional campaign with the popular fast-food chain McDonald's, purchasers of an "Active Meal" could receive one of four Yourself!Fitness DVDs, playable in a standard DVD player, which contains a rigid workout regimen also led by Maya. Each disc is dedicated to a certain theme—Yoga, cardio, strength training, or "core" training—and contains workouts that are 15 minutes in length.
Reception
The Xbox version received "favorable" reviews, while the PlayStation 2 and Wii versions received "average" reviews, according to the review aggregation website Metacritic. In January 2006, CiN Weekly gave the game a score of 77 out of 100 and said that, "Though a little cheesy, it's a good way to create a customized home workout with menu suggestions and progress chart." Detroit Free Press, however, gave the Xbox version two stars out of four and stated, "It's a shame that the disc, which offers 4,500 recipes and meal plans also printable at the program's Web site, is so inflexible about allowing other workouts into its tracking system, and that what should be the central focus, the workouts themselves, is so lackluster."
