BodyMedia provides insight into your body’s physical state through four scientific measurements. It uses a pedometer-like device to measure physical motion and steps, but also has galvanic skin response, skin temperature and heat flux measures. The BodyMedia API will give application developers access to all these metrics on your body’s recent activity. FitBit is in a similar space, but FitBit just doesn’t have as many measurements to use in its applications.

The TrainingPeaks SOAP API helps coaches and athletes use the platform to add users, upload data, get works outs and achieve peak performance.
