1. A computer-implemented method comprising:
- prompting, at a first location, a user to perform an exercise comprising multiple repetitions;
determining a location of a computer device on a body of the user, from data received from a sensor integrated into an item of apparel worn by the user;
calculating, by the computer device, an angle between a first body part and a second body part of the user, based on the determined location;
monitoring, at the first location, with at least a first sensor of the computer device, a form of the user while performing the exercise, based on the calculated angle, wherein the form of the user comprises at least two form scores and at least two completeness modifiers corresponding to at least two parts of the exercise, wherein the at least two completeness modifiers adjust the at least two form scores based on how well the user'"'"'s form corresponds to a desired form, and wherein each of the at least two completeness modifiers is a weighted average comprising a decaying function that weights more heavily recent repetitions of the exercise; and
calculating, by a processor, an energy expenditure estimate for the user performing the exercise based on a type of the exercise, the form of the user, and at least two contribution values that correlate the at least two form scores with energy expenditure.

Abstract
System and methods are provided for prompting a user to perform an exercise and to monitor the exercise. The form of the user may be monitored, such as with one or more video cameras and/or other sensors, to determine how well the user is performing the exercise. Energy expenditure is estimated based factors that include the type of the exercise, the form of the user and a contribution value that associates energy expenditure with form.
