US Patent 10413773 Workout machine

A workout machine adapted to be used with a smart device with built-in accelerometers and an app. It has a deck movable relative to its base and a lifting gear assembly operationally using a cable via a pulley to a lifting handle. A user location pivot arm is fixed to the deck, and a screen stand extends from the deck, where the user location pivot arm and screen stand are pivotably attached to a screen platform that can hold the smart device during a workout. The user's position on the deck can indicate the resistance of the exercise based on a percentage of the user's own weight as lifted with each repetition. The fulcrum concept combined with a user location feature allow an app of the smart device to support and analyze a workout.
