Training load and readiness

Training load and readiness

Both pages open from the cards at the top of Workouts. They are part of Plus; on Free each page is a locked summary with an Upgrade to Plus button.

The Training Load page on a Free account: Unlock training load, a line about fatigue, fitness, and form with projections, and an Upgrade to Plus button
Two cards: Training Load, described as fatigue, fitness, and form across every workout with projections, and Readiness, a daily score with intensity guidance for today

Training Load

The Training Load page: Fatigue, Fitness, and Form numbers with fatigue well above fitness; max heart rate shown as the default; acute to chronic load ratio marked context only; a Next 7 days projected form chart with a warning about deep fatigue; and a Training Load Trend chart over 30 days with fatigue, fitness, and form lines
A week of daily sessions on a new account: fatigue has risen faster than fitness, so form is negative.

Load points

Every workout earns load points from how long and how hard it was. Where the measure comes from depends on the session:

SessionIntensity from
Running or swimmingPace against your threshold pace
CyclingPower against your threshold power
StrengthVolume lifted
Anything with heart rateHeart rate against your max and threshold
Anything elseYour perceived effort rating

Days with no workout score zero, which is how rest lowers fatigue.

Fatigue, fitness, and form

NumberWhat it tracks
FatigueA weighted average of load over roughly the last 7 days. Rises and falls quickly.
FitnessA weighted average over roughly the last 42 days. Rises and falls slowly.
FormFitness minus fatigue. Positive means fresh; negative means carrying fatigue.

Two lines under the numbers give context. Max heart rate is what turns heart rate into intensity; the default is an estimate, and a value set on your profile takes precedence. Acute:chronic load ratio compares the last week with the last month and is shown for context only.

Projection and trend

Next 7 days (projected) forecasts form from the sessions on your calendar. Dashed values are projections. A warning names the date when the schedule would push you into deep fatigue, so you can place a recovery day before it.

Training Load Trend plots the three lines over 7, 30, or 90 days. Until you have a few workouts the page reads Building your training baseline; a period with nothing in it reads No training data for this period yet.

Training Readiness

The Training Readiness page: the level with its form value, Recommended Intensity, a Volume Warning that this week's training volume is far above last week's with a link to the 10% rule, and a note that nutrition was not included because too few days were logged

The level comes straight from form:

FormLevelRecommended intensity
Above 15FreshHigh
5 to 15ReadyHigh
Minus 5 to 5NeutralModerate
Minus 15 to minus 5FatiguedLow / Recovery
Below minus 15OvertrainedRest Day

Two adjustments can lower the recommendation by one step each, and they stack:

  • Volume Warning. If this week’s load is more than 10 percent above last week’s, a High recommendation becomes Moderate. The warning shows the percentage and links to the 10 percent rule.
  • Nutrition. If your average intake over the last 3 days is more than 20 percent below your calorie target, the recommendation drops one level and the page says why. With no calorie target or fewer than 3 logged days, the page notes that nutrition was not included.

With fewer than 7 days of history the page reads Still building your baseline instead of a level.

What to do with it

  • Form a little negative during a training block is expected. Deeply negative form for several days in a row means you should rest.
  • Before an event, plan easier days so form turns positive while fitness is still high.
  • The forecast uses the sessions on your calendar, so its warning is accurate only if the planned sessions are realistic.
  • If readiness is low but you feel fine, check your max heart rate and look for duplicate workouts; see Readiness looks too low in the first week.

See Understand your readiness for how to read the levels day to day, and Insights and suggestions for what the dashboard does with them.
