No pain, no gain, no idea what half these terms mean.
The energy system that breaks down carbohydrates without oxygen for high-intensity efforts lasting 30 seconds to 2 minutes. It's your body's backup generator that produces energy fast but leaves you with that burning sensation and lactate accumulation.
Repetitions performed with intentional momentum, body English, or compromised form to move weight beyond strict capability—either a legitimate advanced technique or proof you loaded too much, depending on who's watching.
Exercise or biological processes that occur without oxygen, essentially your body's emergency backup generator when you're too out of shape to breathe properly. In fitness contexts, it's the kind of high-intensity workout that makes you question your life choices while your muscles scream for mercy. Scientists use it to describe organisms that thrive in oxygen-free environments, unlike gym-goers who simply survive them.
Bodyweight exercises that make you realize just how heavy your own body actually is, requiring minimal equipment beyond your determination and a floor. It's the democratizing force in fitness that proves you don't need an expensive gym membership to suffer through burpees and push-ups. Essentially, it's the ancient Greek art of getting jacked using nothing but gravity and poor life choices.
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.
Building a broad foundation of fitness qualities (strength, endurance, mobility, work capacity) rather than specializing immediately. It's the 'learn to walk before you sprint' phase that impatient athletes skip, then wonder why they're always injured.
Blood Flow Restriction training—strapping bands around your limbs to trap blood in muscles during light exercise, tricking them into growing with kindergarten weights. Science that looks like you're cutting off circulation because you basically are.
The exercise intensity at which lactate begins accumulating in your blood faster than your body can clear it. The invisible line between 'I can do this all day' and 'I need to stop immediately.'
The supplementary exercises performed after your main lifts to address weaknesses, build muscle, or fix imbalances. The vegetables of your workout—you know you should do them but they're less exciting than the main course.
Euphemistic slang for menstruation, particularly relevant when discussing how hormonal fluctuations affect training performance and recovery. Not to be confused with the Discovery Channel programming event that also makes people feel crummy.
A training method using bands or chains that increase resistance throughout the range of motion, forcing your muscles to work harder where they're strongest. It's biomechanics' way of saying 'no easy parts allowed.'
Muscles emphasized for aesthetic appearance rather than functional strength—typically chest, arms, and abs—that look impressive shirtless but contribute minimally to actual athletic performance or real-world utility.
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.
Complete glycogen depletion during endurance exercise, causing sudden, catastrophic fatigue and the overwhelming desire to lie down anywhere. Cyclists' worst nightmare and the reason why energy gels exist.
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 ballistic hip hinge movement propelling a kettlebell forward using posterior chain power. Looks like an aggressive bell-ringing motion and feels like your glutes are staging a revolution.
A planned short-term increase in training load that temporarily decreases performance, followed by adaptation and improvement during recovery. It's intentionally digging yourself into a hole with the confidence you can climb back out stronger.
Exercise where your muscles contract and burn like crazy but nothing actually moves, making you look like you're frozen in an extremely uncomfortable position. These static holds build strength without changing muscle length, so you're basically flexing as hard as possible while staying perfectly still like a sweaty statue. Wall sits and planks are prime examples of this special kind of motionless torture.
A submaximal weight used for program calculations, typically 85-90% of your true one-rep max, because programming off your absolute maximum is how you get injured and disappointed simultaneously. It's the humble approach to getting stronger.
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.
Metabolic conditioning—high-intensity circuits designed to improve your body's energy systems and work capacity while simultaneously destroying your will to continue. Cardio's angry, violent cousin.
The slow, awkward walk to re-rack weights after failing a lift or having to bail on a set. Not to be confused with the college version involving last night's outfit.
A gym-goer who disproportionately emphasizes arm training over compound movements and leg day, typically found monopolizing the dumbbell rack while their chicken legs tell their own story.
Repetitive practice exercises designed to bore a skill into your muscle memory through sheer monotonous repetition. Whether you're in the military, on a sports team, or preparing for emergencies, drills are the universal language of 'do this boring thing over and over until you can do it in your sleep.' Athletes particularly love complaining about them while secretly knowing they're the reason they don't trip over their own feet during competition.
