A new patent published Tuesday suggests that the iWatch may be able to able to detect if the user is lifting a weightlifting bar, and count and display the recorded repetitions. Metrics related to intervals between movements could be compared against previous sessions and displayed on an iOS device so that the user could track their progress over multiple sessions.
Interestingly the patent — which was filed in 2012 — specifically mentions a shoe-based sensor, similar to fitness-tracking sneakers like the Nike Hyperdunk+ basketball tracking shoes. In the years since then, however, Apple has pulled back on patent references to shoe wear-out sensors and unitless measurements, but kept the body-bar sensing system and associated watch readout. Other possible devices named in the patent include potential future generation iPods and iPhones.
