So, from the top, you have stress vs recovery/adaptation. Workout ==> Rest ==> Get stronger ==> Decreasing I:E ==> Workout again to get even stronger
Inadequate or excess stress==> Failure to adapt
Inadequate rest ==> Upset recovery/adaptation + accumulation of fatigue ==> Increasing cardiac drift and/or RPE + Abnormally low HR
Excess rest ==> Revert to previous fitness level
Fatigue ==> Rapid changes in drift and HR
Fitness ==> Slower changes in HR
Endurance ==> Even slower changes in drift
Adjustments ==> Intensity, duration, or frequency (microcycle)
Adjust duration first unless:
.- time is limited ==> increase intensity
- adequate endurance achieved ==> increase intensity
- fatigue accumulation ==> decrease frequency
