interference effect

Definition

The phenomenon where concurrent endurance and strength training can compromise gains in both modalities, because your body isn't a limitless adaptation machine. It's biology's version of 'you can't have your cake and deadlift too.'

Example Usage

He experienced the interference effect trying to build a powerlifting total while marathon training, excelling at neither.

Origin

From exercise science research in the 1980s studying concurrent training adaptations

Fun Fact

The interference effect is why elite powerlifters aren't doing marathon training and vice versa—specialization matters when you want to be actually good.
