Training while sick

These notes combine advice from 4 reviewed passages across 4 workouts.

Overview

Coach’s claim

A workout during illness can help you get better, and a workout at a sufficient level is enough to strengthen you. Extra exertion beyond that level can weaken the overall system and slow the healing of the illness. [3] [4]

Training despite weakness

Coach’s claim

Training while sick is a much better investment than skipping training. When weakness from the illness makes you not want to train, train anyway at that moment. [4]

Coach’s claim

Most people skip training when sick, even when they know training would help, and choose to get through the day instead. Weakness from illness takes away the desire to train, so you do not feel like doing it. [4]

Avoiding overstrain

Coach’s claim

Do not overstrain your body while sick. After a good workout, doing more can weaken the overall system and slow the healing of the illness. A workout at a sufficient level is enough to strengthen you, and feeling well matters more than doing more. [3]

Rest and slowing down

Coach’s claim

When you feel sick, rest. Coach said Can’s training would sometimes be slowed while he had diarrhea. [1] [2]

Coach’s experience

In his own experience, the coach knows good athletes who also skip training when sick. [4]
