Apple is set to move into the fitness market accordingt to Apple Insider. Not content with trying to mold the communication and entertainment habits of the public, Apple may also have designs on encouraging better health practices as well.

AppleInsider earlier today discovered some some patent filings indicating Apple may be working on a digital fitness companion system for its iPhone and iPods.

According to the blog, the filings outline components including "an iTunes-like software application, hardware-based heart rate and physiological sensors, a rewards tracker, and a component to facilitate synchronous group activities." Users would answer the software's interview questions on everything from fitness goals and interests to health history and, according to the filings, possibly even "non-health related topics, e.g., spirituality/religion, identity (e.g., sense of belonging), relationships, career, financial condition, environment, hobbies, interests, other personal information, and goals regarding the same." Once the system knows your deepest hopes and secrets, it would create a customized workout program in which progress could be monitored by sensors attached to future iPhones and iPods. And no, we're not the first to see an iBod joke in there somewhere.
