# Power Output

I posted a result, but I received a 0 for my power output. Why am I not receiving a power output result?

**APP:**

A Weigh-In is necessary for power output calculations. This is because we need your height and weight (the numbers we use to calculate power output.). Log a weigh-in and enter your measurements via the quick log button (+) at the bottom of the screen to start seeing power output calculations.

**WEB:**

You don't have any power output data because you haven't logged a Weigh-In or set your measurements. From the **web**, a Weigh-In can be logged via the "Log" button in the header. Click on "Weigh-In" from the drop-down menu.

You can set Measurements from the web and the app. These consist of your squat, shoulder, deadlift, and overhead heights for lifting exercises. Without this data we can estimate some of the work done, but you'll get better results once you post accurate measurements for each. We use a mathematical formula to determine the work done in each repetition for each exercise that you do.

Fromt he Web, go to your personal drop-down menu in the header and click on "edit prefs".

From the app your measurements can be entered by selecting the side bar menu >> Work formular measurements.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://btwb.gitbook.io/btwb/general/power-output.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
