Sports

According to a study on elderly people, when asked, most of the participants did not see sports such as golf, bowling, and swimming to be forms of exercise (2).
This is a really helpful factor since sport really is exercise, and can be just as effective if not more than working out in a gym. Sports can be a dynamic, full body exercise but when people enjoy it, it may not feel like they are doing something that requires as much effort as going to the gym.

A number of subjects chose to opt for lighter intensity activities such as bowling, golf, or swimming because they were less taxing than a trip to the gym. (2)
On top of this, these activities offer a better chance for participants to be social rather than focusing solely on their exercise.
A number of participants also stated that they enjoy the competitive nature of their sport whether they are competing against themselves or others. (2)
