APP:
Use the "+" button in the footer menu of the home screen to build a workout and log a result for it. Click on the "New" tile when presented with the various options.
The logging flow will take you through the steps to log a new result.
WEB:
If you aren't planning for yourself, or if you aren't part of a gym that is actively planning workouts for its members, odds are your Whiteboard calendar is empty. Don't fret! You can log your own results at any time.
Click on the "log" link in the navigation menu and then on "workout" from the drop-down menu that appears.
You'll be given some options to help you along the way. You'll be able to either find and log a result or build a new workout and log a result for it. The buttons are designed to make the process easy.
Find and Log
This option is for workouts you know already exist via the btwb database. Select the button that most appropriately describes what you are looking for. Though each button has a default filter already in place, you can use any of the buttons to find any workout you are looking for.
Build and Log
This option is for creating workouts you believe to be unique to the site. Follow the steps laid out for you. The templates make creating the most popular WOD types easy. Keep in mind that building a workout that already exists on the site doesn't create a new version, it simply finds and pulls up the existing workout. In other words, no matter how many times you try to create "Fran" there will always only be the one. (That's more than enough!)
Logging a result this way will display the workout on your Whiteboard Calendar in blue (the color of your personal track).
