Abstract: Introduced here are computer-implemented platforms (also referred to as “pose monitoring platforms”) that are designed to improve adherence to, and success of, programs requiring performance of physical activities. As part of a program, a participant may be requested to engage with a pose monitoring platform to perform a single physical activity, multiple repetitions of a single physical activity, or multiple repetitions of multiple physical activities. The pose monitoring platform can determine, for example, using a neural network that has parallel branches, whether digital images of the participant's environment includes certain body parts and then estimate poses of those body parts. The pose monitoring platform can use the estimated poses to guide the participant through the program, such as by providing instructions for performing the physical activities.
