No pain, no gain, no idea what half these terms mean.
The interconnected system of body segments and joints that work together to produce movement. The reason your knee pain might actually be a hip problem, and why bodies are annoyingly complicated.
A group fitness format using light weights and high reps to music, like BodyPump. Aerobics married strength training and produced exhausting offspring.
A breathing technique involving equal counts for inhale, hold, exhale, and hold (like 4-4-4-4), used to calm the nervous system between sets or before competition. Meditation for meatheads.
A weighted training implement pushed or pulled across the ground, beloved by strength coaches for building power and conditioning while destroying athletes' will to live. Also known as a prowler, which is appropriately named given how it stalks your nightmares.
The distance a joint moves during an exercise, abbreviated ROM. Full ROM builds muscle and flexibility; partial ROM builds ego and Instagram content.
Training with submaximal weights (50-70%) moved at maximum speed to develop explosive power. Louie Simmons' way of making light weights feel purposeful.
An exercise targeting a single muscle group or joint, like bicep curls or leg extensions. Perfect for building Instagram muscles while neglecting functional strength.
Walking while holding heavy weights at your sides, mimicking the gait of someone carrying groceries who refused to make a second trip. Deceptively simple until your grip, core, and will to continue all fail simultaneously.
A gymnastics movement transitioning from a pull-up to a dip in one fluid motion, combining pulling and pushing strength with technique. The exercise that humbles people who thought they were strong at pull-ups.
A training method involving frequent practice of a movement throughout the day at submaximal effort to build neuromuscular efficiency. Popularized by Pavel Tsatsouline for making impossible skills possible through sheer repetition.
In physics, the product of mass times velocity that explains why things in motion stay in motion—and why stopping a runaway project feels impossible. More colloquially, it's that magical force that makes everyone want to jump on the bandwagon once success starts building. Losing momentum is every athlete's and startup founder's worst nightmare.
The maximum power output a cyclist can sustain for roughly an hour without blowing up, measured in watts and used to set training zones. It's cycling's version of lactate threshold, now with more expensive gadgets to measure your suffering precisely.
Muscle growth from increasing the size and number of contractile proteins (myofibrils), making muscles denser and stronger rather than just puffier. It's the 'actual strength' type of muscle growth as opposed to just looking swole.
A workout format performing different exercises back-to-back with minimal rest between stations, creating a cardio and strength hybrid that makes you wonder if catching your breath is still a thing humans get to do.
Continuing a set until you physically cannot complete another rep with proper form, theoretically maximizing muscle stimulus. The point where confidence becomes concentric weakness.
A method of estimating body composition by passing a weak electrical current through the body to measure resistance. The scale that judges you with science and electricity simultaneously.
Active movements that take joints through their range of motion, used to warm up before exercise. The bouncy, movement-based stretching that makes you look like you're practicing interpretive dance.
In baseball, a cut fastball that breaks slightly away from same-handed hitters, moving late enough to turn solid contact into weak ground balls. Popularized by Mariano Rivera, who rode this single pitch to the Hall of Fame while making professional hitters look foolish for two decades. It's the pitcher's equivalent of having one really good party trick and refusing to learn any others.
The amount of work performed per unit of time, typically increased by reducing rest periods while maintaining volume. It's the principle that if regular training is too easy, why not make yourself miserable by doing the same amount faster?
The phenomenon where the sum of your single-leg strength exceeds your double-leg strength, because apparently your nervous system can't fully activate both legs simultaneously. It's your body's way of preventing you from trying to jump over buildings.
The sudden, catastrophic depletion of glycogen stores during endurance exercise, causing extreme fatigue and mental fog. The metabolic equivalent of your car not sputtering but just stopping.
Workout Of the Day - a pre-programmed training session, most associated with CrossFit. The mysterious ritual that determines whether you walk normally tomorrow.
A set structure with brief rest periods (10-30 seconds) between small rep clusters, allowing higher quality reps with heavier weights. The commercial break approach to strength training.
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.
