A seamless access control system includes a local access assembly, a wearable mobile device, a storage medium, and a processor. The assembly is adapted to operate between access and no-access states, and includes a controller to effect actuation between the states, and a signal transceiver. The wearable mobile device is worn by a user, and includes an inertial measurement unit (IMU) sensor system configured to detect a performed inherent gesture performed by the user, and being at least a portion of a user exercise to gain entry. The storage medium and the processor are configured to receive the performed inherent gesture and execute an application to compare the performed inherent gesture to the preprogrammed inherent gesture, and thereby conditionally output a command signal to the local access assembly via the transceiver to effect actuation between states, and prior to completion of the user exercise to gain entry.
