A training load is a metric FYTT calculates for you. Every day, each athlete gets the load they logged that day, the total over a period you choose, and a workload ratio that compares that period with a longer baseline. Nobody types these numbers: FYTT works them out from the workouts athletes log, or from another metric you record. This guide covers creating a training load, reading its values, and changing or deleting one.
What a training load gives you
Each training load gives every athlete three values a day: Daily, what they logged that day; a total such as 7-day total, the sum over your period ending that day; and a ratio such as Ratio (7:28), the period's load against their longer-term average. Charts, reports, leaderboards, and automations list each by its full name, such as "7-Day Volume · Ratio (7:14)". A load calculated from another metric has no Daily value of its own, since its daily values are that metric's.
Creating a training load
On the Metrics tab, click Add metric, then choose Training load (1).
In New training load:
Enter a Name and pick a Color.
Under Starting point, pick a preset (1). The summary (2) restates what each athlete will get as you change settings.
Adjust the Calculation if you need to (see below).
Click Create.
FYTT then calculates the last 90 days for every athlete, usually within a few minutes. The data page shows Calculating the last 90 days until it's done.
Choosing a starting point
5-Day Volume and 7-Day Volume total reps × weight, Weekly Distance totals distance, and Weekly Training Time totals time under work, each from logged sets with a rolling-average ratio over four times the period. Custom leaves every setting to you. Change any setting by hand and the starting point reads Custom; the load works the same.
Logged sets or another metric
Source decides where the daily values come from:
Logged sets totals the sets athletes log in their workouts. Choose What to total: Tonnage (reps × weight), Reps, Time, Distance, Energy, or Power. Weight, distance, and energy also take a Unit, used for everyone. Under Exercises, keep All exercises or choose Specific exercises to count only those.
Another metric totals a metric you already record, such as session minutes, GPS distance, or pitch counts. Pick one whose daily values add up, not a max, a best, or a score. Assessments, sprint profiles, surveys, and other training loads can't be a source. Values read in arbitrary units (AU).
If you delete the source metric, the load stops updating. FYTT warns you before the delete, and the load's data page then says Source metric deleted: edit the load and choose another metric.
The period and the workload ratio
Period, in days (1) is how many days the total covers, ending each day. It must be at least 2, and it's also the recent side of the ratio.
The ratio, often called ACWR (acute:chronic workload ratio), divides the athlete's average over the period by their average over the Chronic window, in days (2). The window starts at four times the period, follows the period until you edit it, and must be longer than it. Method (3) sets the averaging: Rolling average counts every day the same, and EWMA weights recent days more.
Read the ratio as a comparison with what the athlete is used to. Around 1.0 means recent load matches their baseline; well above 1.0 is a spike, and below 1.0 is less than usual. What ratio values mean (4) lists the ranges commonly cited in research, which the panel calls guides, not rules. How you act on them is your coaching call.
Under Settings, add a Description, turn on Visible to athletes so athletes see their own values in the app, or set Ranking for leaderboards. None of these change the values.
Reading the values
Click View data beside the load on the Metrics tab, or in its panel. The rail restates the calculation and lists the names the load goes by in charts, reports, and automations (1). The table shows each athlete's daily values for the last 7 days, the total (2), and the ratio (3) as of the date in the toolbar (4), which reads Today until you pick another. Hover a ratio to see the two averages behind it.
On the Data tab, a training load adds its total (1) and its ratio (2) as columns. Click either header to open the load's data page.
Why a ratio is blank
The ratio needs a full chronic window of history: with a 28-day window, an athlete needs 28 days before they have one. Until then it's blank on the data page (hovering says Needs 28 days of history) and a dash on the Data tab. It's also blank when the athlete logged nothing across the chronic window, since there's no baseline. Their daily values and total still show.
Why cells can't be edited
Training load values are calculated, not recorded, so every cell is read-only and can't be overridden. To change the values, change the calculation.
When values update
Values update as athletes log workouts. A load on another metric updates when that metric is recorded, by hand or by import.
Using a training load elsewhere
In Automations, a condition lists the load's values, such as its total or ratio, not the load itself. Group reports, profile reports, and leaderboards list them like any metric: see Reports. A transfer doesn't copy training loads; create the load again in the other organization.
To check a workload ratio without setting up a load, ask Flex, which computes ACWR in an analysis. A formula can't look back over time, so a rolling total or ratio is always a training load.
Changing or deleting a training load
Click the load's name on the Metrics tab to open Edit training load, make your changes, and click Save changes. A change under Calculation asks first: Recalculate 90 days of history? names what you changed, and Save and recalculate replaces the last 90 days of values for every athlete. Reports, leaderboards, and automations then show the new numbers. A new name, color, or setting saves without asking.
Recalculating replaces history
The old values aren't kept. To compare two ways of counting load, create a second training load rather than editing the first.
To delete one, click Delete in its panel and confirm with Delete metric. Every athlete's values for it are removed, and charts, reports, and automations that use it lose them. This can't be undone. For metrics in general, see Metrics.
