Managing form (training stress balance)

To review our main points: form is the proper balance of fitness and freshness.
Fitness is based on training stress or training load.
So, take our thinking one step further:

  1. Form = Fitness + freshness
  2. Fitness is the result of training stress
  3. Freshness is the result of rest
  4. Therefore, form comes from the combination of training stress and rest
  5. Form can be renamed “training stress balance”

TSB thus represents how well you have been juggling your training load and your rest periods. If you want to create form, you must have the proper balance of the two. If your TSB is a positive number, this indicates more freshness.  You would have a good chance of riding well during those “positive” days; you are both fit and fresh.
When your TSB is a negative number, this indicates more fatigue. You are most likely tired from a high training load, which could mean that both your CTL (Chronic training load) and your ATL (Acute training load) are too high. In the Training peaks, Wko software, and Strava premium the Performance chart puts these concepts into a visual format that can help you to balance your training stress.

In the end the big question is: “How can a rider know how much is enough?”. The answer to that question could lies in the power meter and and the software you use with It.
By using your power meter and the Performance manager chart, you can begin to determine your personal optimal training load. It is possibile to mathematically quantify “when enough is enough”.
