No pain, no gain, no idea what half these terms mean.
A weight progression scheme where you either increase weight and decrease reps each set (ascending) or the reverse (descending). It's the mathematical approach to training that makes you feel smart until you're too exhausted to count.
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 organization of your workout schedule by muscle groups or movement patterns across different days. It's how you scientifically justify why today isn't the day for that body part you're trying to avoid training.
The euphoric state experienced during or after prolonged running, caused by endocannabinoid and endorphin release. Non-runners remain skeptical this exists, while runners evangelically insist it's worth the joint damage.
The controlled lowering phase of an exercise, typically performed with heavier weight than you can lift concentrically. It's the part of the rep where gravity becomes your training partner and your muscles scream about the betrayal.
Exercises focused on improving joint range of motion and movement quality, typically involving controlled stretches and movement patterns. It's what you should be doing instead of scrolling Instagram between sets.
A momentum-based pull-up variation using hip drive and swing, primarily associated with CrossFit. Purists consider it cheating; pragmatists consider it efficient; orthopedic surgeons consider it job security.
Legs that pull off the ultimate deceptive maneuver by looking unimpressive at rest but transforming into sculpted muscle columns the moment they're flexed. Like shape-shifting robots, these calves and thighs have more than meets the eye—literally a case of Autobots versus Flab-icons.
The intense muscle discomfort during high-rep sets from metabolite accumulation and reduced pH, not actual tissue damage despite feeling like your muscles are melting. No pain, presumably gains.
Every Minute On the Minute—complete a set amount of work at the start of each minute, resting whatever time remains. A workout format where the clock is both timer and tormentor.
As Many Reps/Rounds As Possible within a time limit—a workout format designed to make you question both your physical limits and your decision-making ability. The fitness version of 'how much can you eat?'
Your aerobic system and cardiovascular capacity—the unglamorous base fitness that determines whether you can sustain any athletic effort. Slow to build, embarrassing to lack.
Continuing a set until you physically cannot complete another rep with proper form, theoretically maximizing muscle stimulus. The point where confidence becomes concentric weakness.
In fitness terms, what your muscle does when it's actually working—shortening under tension to create movement. Not to be confused with economic contractions (your wallet getting lighter) or labor contractions (a completely different kind of pain), though all three can make you sweat profusely.
Explosive jumping and bounding exercises that train muscles to exert maximum force in minimal time. Basically teaching your muscles to become tiny nuclear reactors of power.
The force produced when muscles contract against resistance, considered a primary driver of muscle growth. The scientific explanation for why muscles get bigger when you make them work really, really hard.
A systematic planning of athletic training that divides your program into specific time blocks, each with particular goals. It's essentially meal-prepping for your muscles, but over months instead of Sundays.
Shortened term for rhabdomyolysis, the catastrophic muscle breakdown that releases proteins into your bloodstream and can destroy your kidneys. When someone tells you they got rhabdo from a workout, they went from fitness enthusiast to medical emergency in record time.
The vanity-driven muscle groups that people obsessively train because they're visible in gym mirrors—chest, biceps, abs—while neglecting everything else. The fitness equivalent of a movie set facade with nothing behind it.
The imaginary workout that never happens despite your best intentions, named for standing in your kitchen thinking about exercise while eating instead. The most popular training program among procrastinators.
A lifting technique where you bounce the weight off your body or the floor between reps instead of pausing and resetting, conserving energy but sacrificing control. The express lane of questionable form.
Rate of Perceived Exertion—a subjective 1-10 scale measuring how hard you're working based on feel rather than numbers. It's like rating your life stress, but for deadlifts.
A muscle contraction where the muscle shortens while generating force, like the upward phase of a bicep curl. The fun part of lifting where you actually look strong.
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.
