Intensity (Training Intensity)

Definition

How hard you're working relative to your maximum capacity, usually expressed as a percentage of 1RM—not to be confused with effort, which is what Instagram claims to measure.

Example Usage

That set at 85% of my 1RM was high intensity work.

Origin

Quantitative training metric from strength research

Fun Fact

There's an inverse relationship between intensity and volume: the heavier you lift, the fewer reps you can do.

weightlifting

A sport where competitors lift progressively heavier weights in two main events: the snatch and the clean and jerk, both of which sound vaguely inappropriate but are actually technical Olympic lifts. Unlike your average gym bro's bicep curls, this requires explosive power, perfect technique, and the ability to grunt louder than everyone else. It's the difference between fitness and competitive masochism.
