When monitoring your Training Effect, you no longer need to stay within pre-defined heart rate
zones because the TE shows the actual result of the workout regardless of what your exact heart
rate is. This gives you freedom from the zone alarms while still reaching the desired result.
Suunto t4 shows the Training Effect in two ways. The lower right side of the display shows it as a
graph. It is so shown as a number in the center of the screen instead of the heart rate reading.
The TE of each workout is defined by the highest number (from 1.1 to 5.0) reached during the
workout. The peak TE reached stays visible on the graph. If you want to further increase the effect
after a lower intensity period, you need to work-out harder to push the peak higher.

Result of the workout
Enhances recovery (short workout) or develops base endurance
(over 1 hour session). Ideal for fat burning. Does not improve
maximal performance.
Maintains aerobic fitness. Builds base for harder training in the
future. Does little to improve maximal performance.
Improves aerobic fitness if repeated 2–4 times a week. No
special recovery requirements.
Rapidly improves aerobic fitness if repeated 1–2 times a week.
A few easier exercise sessions (TE 1–2) needed for recovery.
Dramatic increase in aerobic fitness if adequate recovery is al-
lowed afterwards. High demand for recovery. Increased risk of
overtraining if repeated too often.
