Exercise Balance and Training Status
The exercise balance section shows the relationship between what you have been doing recently and what your body has grown accustomed to over a longer period. It helps you see whether you are training in a sustainable way.
Two Time Windows
Yuelu tracks your daily workout load across two windows:
- Recent load (7 days): A rolling view of your workout load over the past week. This reflects what your body has been asked to handle recently.
- Baseline load (28 days): A rolling view over the past four weeks. This represents the level of activity your body has adapted to.
The system compares these two windows. When the recent load is close to or slightly above your baseline, training is generally sustainable. When recent load rises sharply above your baseline, the system flags the change.
Exercise Load Ratio
The balance section shows a single ratio — recent load divided by baseline load. This number tells you how your current week compares to your month-long trend:
- At or below 1.0 means your recent activity is in line with (or below) your established habits.
- Above 1.0 means you have been training more than usual this week.
- Significantly above 1.0 means the recent increase is large relative to your baseline.
Rest days count in both windows. A week with only one hard workout will show a lower recent load than a week with five hard workouts, even if the single session was intense.
Training Status
When enough data is available, the system assigns a training status based on the relationship between recent and baseline load:
- Efficient: Your recent load is slightly above your baseline. This is typically a productive training phase where fitness gains are expected.
- Maintenance: Recent load matches your baseline. You are sustaining your current level.
- Recovering: Recent load has dropped below baseline after a period of higher activity. Your body is rebuilding.
- Detraining: Recent load is well below your baseline without a prior high-load phase. Activity has decreased and fitness adaptations may start to fade.
- Overreaching: Recent load has risen substantially above your baseline. This can be part of a planned training block, but sustained overreaching without recovery increases fatigue risk.
Injury Risk
The exercise load card also shows an injury risk indicator based on how much the recent load exceeds the baseline:
- Safe (low risk): Recent load is within a range that your baseline supports. Training is generally sustainable.
- Slightly elevated: Recent load is noticeably above your baseline. Pay attention to recovery and consider reducing intensity.
- High risk: Recent load has increased sharply. The risk of overuse injury rises. Consider reducing volume, lowering intensity, or taking a rest day.
This is a load-change signal, not an injury prediction. Individual injury risk depends on many factors beyond training load, including sleep, nutrition, movement patterns, and personal history.
The Trend Chart
The 7-day trend chart shows your daily workout load over the past week. Use it to see:
- Whether your load has been increasing, decreasing, or staying steady
- How your training is distributed across the week
- Whether rest days are providing adequate recovery
A balanced week typically includes a mix of higher-load and lower-load days, rather than the same intensity every day.
