You don't have any power output data because you haven't logged a weigh-in or set your measurements. A weigh-in can be logged via the "log" button in the header. Click on "weigh-in" from the drop-down menu. A weigh-in will give us your height and weight.

Measurements are a little different. This 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. Go to your personal drop-down menu in the header and click on "edit prefs".

Then select a measurement unit and enter in the appropriate numbers for each of the categories.

Since we don't have a formula for every exercise (especially those added by individual gyms) your work done may differ from what is displayed.
