Rename "fitness" to "recent training load"

Hey Roger,

Here is our support article that reviews Fitness & Freshness so yourself and other members can have context on what the Fitness & Freshness feature covers.

As for the name change of the feature, we appreciate this feedback.
Other than the name, if you have make one change would you change anything else about fitness & freshness?

If you rename it to (recent/4 week) training load you don't need to change anything. 

If you keep calling it "fitness" you need to use metrics like resting heart rates, heart rate variability, speed vs. heart rate, etc, but an app that lives on a phone doesn't't collect any of that. And if you find a way to pull that data from Garmin/Fitbit/etc you'd just replicate what's already in their apps.

So just call it "training volume" and leave fitness tracking to devices and apps that have access to data that Strava can't see.
