No pain, no gain, no idea what half these terms mean.
Resting Metabolic Rate: the number of calories your body burns just existing in a chair, doing nothing but maintaining life functions. It's the baseline caloric cost of your meat prison before you add actual activity, typically measured first thing in the morning.
Energy system training designed to improve work capacity, usually involving high-intensity intervals or circuit training. What happens when someone decides cardio wasn't quite miserable enough.
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.
The moderate-intensity training zone between comfortable aerobic work and hard threshold efforts, also known as 'no man's land' because it's allegedly too hard for easy days and too easy for hard days. Every endurance athlete's accidental default pace.
The speed and efficiency at which someone completes tasks, often measured by managers who themselves haven't done actual work in years. A metric that supposedly indicates productivity but really just shows how fast you can move before burning out. In sports, refers to a player's hustle and effort, which sounds way more noble than 'how much we can squeeze out of you.'
A short, intense workout designed to torch calories and test mental fortitude in minimal time. Named for the burning sensation in your muscles, lungs, and soul.
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 psychological anxiety and phantom injuries that afflict endurance athletes during pre-race taper periods when training volume drops. Every twinge becomes a career-ending injury in your mind.
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.
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.
An athlete who looks incredibly fit and impressive but whose performance doesn't match their aesthetic. All show, minimal go—the Instagram model of athletic performance.
A fundamental category of human motion (squat, hinge, push, pull, carry, etc.) that transcends specific exercises. It's the taxonomy of movement, helping you organize training instead of randomly doing whatever machine is free.
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.
In sports, that brief timeout where players gather in a tight circle to discuss strategy while pretending the other team can't read their lips. It's the athletic equivalent of a quick business meeting, except with more grunting and fewer PowerPoints. Bonus points if your quarterback actually knows the play they're about to call.
Someone who shares your workout schedule, spots your lifts, and witnesses your gym face at its worst. A relationship built on mutual suffering and the understanding that 'one more rep' is always a lie.
A loaded carry exercise where you grip heavy weights in each hand and walk a specified distance, mimicking a farmer hauling buckets—except farmers probably weren't trying to impress anyone at the local strongman competition. Develops grip strength, core stability, and farmer's tan envy.
The distance a joint moves during an exercise, abbreviated ROM. Full ROM builds muscle and flexibility; partial ROM builds ego and Instagram content.
The study of mechanical laws relating to movement and structure of living organisms. The science that explains why your deadlift form looks like a frightened cat.
Workout Of the Day - a pre-programmed training session, most associated with CrossFit. The mysterious ritual that determines whether you walk normally tomorrow.
Low-intensity exercise performed between harder training sessions to promote blood flow and healing without adding stress. The art of doing something while technically doing nothing.
A hand position where palms face away from the body, also called an overhand grip. The standard grip for pull-ups that makes biceps sad and forearms scream.
A scheduled torture session where you voluntarily subject your body to physical strain in the hopes of looking better in jeans. Can range from a light jog to an intense CrossFit session that leaves you unable to sit on the toilet for three days.
Bodyweight exercises that use minimal equipment and maximal suffering to build strength and endurance through movements like push-ups, pull-ups, and various forms of self-inflicted torture. It's what people did before gym memberships existed, and what fitness influencers rediscovered and rebranded as revolutionary. The word sounds fancy, but it's really just organized sweating.
