An adjustable archery training bow assembly includes a single resistance element and an adjustment mechanism that can be actuated by a user to vary the tension level in the resistance element for training purposes. The training bow also includes a mount for receiving a mobile device, which allows the user to practice various augmented reality-archery training scenarios. The adjustable archery training bow is used to enhance the user's skills, such as his/her strength, stability, and accuracy to help deliver on-target an arrow fired from a real, non-training bow.
