Some of the more popular video games are those that involve movement. Many choose to work out in this manner because it's done in the privacy of home, there are no ongoing fees, and it's convenient. These activities have been criticized because the exercise is not strenuous.
They do provide a good solution, especially for those who don't exercise at all. They encourage light to moderate movement, which is better than a typical sedentary lifestyle. They are motivating as participants try for an improved score.
These games encourage people to think about their fitness level while doing something fun. Multiple family members can challenge each other, which is good for relationships as well as physical health. Finally, they can be a gateway to more challenging activities.
These games have proven especially good for seniors, and are much better than just sitting around.
