No pain, no gain, no idea what half these terms mean.
How quickly your heart rate drops after intense exercise, indicating cardiovascular fitness. A fast recovery means you're fit; a slow one means you should probably do more cardio and less online shopping during workouts.
In fitness circles, this refers to the ratio of fat, muscle, bone, and water in your body—basically your body's ingredient list. It's what trainers obsess over instead of just looking at the scale, because apparently weighing 150 pounds of muscle is vastly superior to weighing 150 pounds of anything else. The buzzword that launched a thousand DEXA scans.
Anything or anyone that interferes with your fitness progress—poor sleep, stress, your friend who always suggests pizza. The imaginary saboteur of swoletopia.
The profuse perspiration experienced after consuming large quantities of protein, typically post-competition or during bulking phases. Your body's way of complaining about its new carnivore diet.
In powerlifting, squatting low enough that the hip crease drops below the top of the knee, the difference between a white light and public humiliation at a meet.
"Long Slow Distance"—extended runs at conversational pace to build aerobic base. Despite the acronym, the only trip involved is the mental journey of running for 2+ hours.
Complete cardiovascular exhaustion where your lungs are on fire and breathing sounds like a broken accordion. Past tired, approaching horizontal.
A satirical nickname for the Oakland Raiders, poking fun at their tendency to dominate early in the season then spectacularly collapse down the stretch.
An opponent or challenge so insignificant that defeating them barely registers on your effort meter. The human equivalent of a training montage montage.
Exhausting your muscle's stored carbohydrates, causing fatigue and performance loss. Why you bonk during marathons.
A stat that measures your ability to make your teammates look good without actually scoring yourself—basically the participation trophy of sports metrics.
Gnarly powder snow so epic that regular skiing vocabulary simply won't do—you need to mash two rad words together. This is the stuff that makes snowboarders quit their jobs and move to the mountains. If you need a snorkel for it, you've found the promised land of winter sports.
The paradoxical condition where working out too much actually makes you weaker, proving that more isn't always better—a concept gym bros refuse to accept. This occurs when athletes don't allow adequate recovery time between sessions, leading to decreased performance, persistent fatigue, and increased injury risk. It's your body's way of saying 'I didn't sign up for this torture schedule.'
The fancy medical term for "your heart and lungs working together," because apparently "breathing and pumping" wasn't scientific enough. This is what fitness professionals say when they want to sound like they went to medical school instead of just getting certified online.
Completing the second half of a race or workout faster than the first half. The pacing strategy that separates the disciplined from the over-enthusiastic who died at mile 2.
The partial or complete loss of training-induced adaptations when you stop exercising. Evolution's reminder that 'use it or lose it' isn't just motivational poster fodder.
The age-related loss of muscle mass and strength, typically beginning around age 30 and accelerating after 60. Biology's way of saying 'use it or lose it' becomes less suggestion and more threat.
Did Not Start—the race result code for when registration optimism meets reality and you bail before the starting gun. At least you don't have a DNF on your record.
The act of coating your hands with magnesium carbonate powder before lifting heavy weights to improve grip and reduce slippage. Also serves as a territorial marking system to show everyone you're serious.
The sudden and devastating energy depletion that occurs when your glycogen stores run empty, typically around mile 20 of a marathon. Your legs turn to concrete and every step becomes an existential negotiation.
A specific phase of training lasting several weeks with a focused goal—strength, hypertrophy, or conditioning. Like a TV series season with a story arc, except the plot is just you getting gradually more tired.
Euphemistic slang for anabolic steroids and performance-enhancing drugs. When someone says they're 'on gear,' they're not talking about their transmission.
A supplement consumed before training, typically containing caffeine and various stimulants to increase energy and focus. It turns regular humans into temporarily jittery superhumans with questionable decision-making abilities and tingling skin.
The total time your muscles spend under tension during a workout session or specific exercise, measured by people who apparently have the mental bandwidth to count seconds while their muscles are screaming. Related to 'time under tension' but encompasses the full training session.
