Definition
The specific stress applied during a workout that triggers adaptation, assuming it's hard enough to matter but not so hard you die. It's the Goldilocks zone of productive suffering that makes you better instead of just tired.
Example Usage
The training stimulus from three sets of five reps at 85% was sufficient to drive strength adaptation without excessive fatigue.
Origin
From exercise science and training theory on stress-adaptation models
Fun Fact
According to the General Adaptation Syndrome, you need a training stimulus strong enough to alarm your body into adapting, but not so strong it puts you in the exhaustion phase.
