A temple of self-improvement filled with medieval torture devices rebranded as exercise equipment, where people pay monthly fees to grunt at mirrors.

In skating and hockey, the metal runner attached to the bottom of skates that allows you to glide gracefully or fall spectacularly, depending on your skill level.

A high-octane racing fuel designed for maximum engine performance. Typically found in vehicles built for speed rather than your average commute.
A Victorian-era martial art where combatants whack each other with wooden sticks while pretending it's sophisticated sword fighting. Popular among 19th-century gentlemen who wanted combat without the actual bloodshed.

A sarcastic or accusatory label for a team or competitor caught using unfair tactics or exploiting loopholes. Typically used in sports when someone's success seems suspiciously convenient.
Revolutions Per Minute—the cadence or speed at which you pedal a bike or strike a running tempo. Cyclists obsess over this; runners less so.
To show off your physique or strength—informal gym slang that's somehow made it into official fitness vocabulary. It's Instagram personified.
The group of muscles along the back of the body including calves, hamstrings, glutes, and back muscles. Basically, everything people ignore until they get injured.
A playground and recreational game similar to baseball, but played with a large rubber ball that is kicked instead of hit with a bat. Players run the bases after kicking the pitched ball, and the defending team tries to get runners out.
