No pain, no gain, no idea what half these terms mean.
Lighter weight sets performed before working sets to prepare muscles, joints, and nervous system for heavy lifting. The part of training responsible adults do but impatient teenagers skip.
Short for metabolic conditioning, high-intensity workouts designed to improve energy system efficiency. Cardio that lifters can respect, barely.
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.
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 muscle contraction where the muscle lengthens while under tension, like lowering a weight. The phase responsible for approximately 90% of your next-day soreness.
Your body's ability to sense its position and movement in space without looking. The mysterious force that usually works great until you try to touch your nose with your eyes closed after spin class.
A subjective scale (usually 1-10 or 6-20) used to measure how hard you feel you're working during exercise. Science's way of asking 'but how do you *feel* about that?' to your cardiovascular system.
The muscles of the trunk and pelvis responsible for stability and force transfer, not just abs. What people train hoping for a six-pack but end up with planks and regret.
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.
In FIFA, the soccer equivalent of unnecessary showboating—when you have a clear shot at goal but decide to chip the keeper just to flex your virtual skills. It's the video game version of dunking on someone who's already down, except you're risking looking like a complete fool if you miss. Named for the slimy, underhanded vibe of rubbing salt in your opponent's wounds.
Training that supposedly translates to real-world movement patterns and daily activities, as opposed to 'non-functional' exercises that only make you better at exercises. The term everyone uses to justify their preferred training style.
The squat, bench press, and deadlift—powerlifting's holy trinity. These three exercises determine who's strong and who just looks strong, much to bodybuilders' annoyance.
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.
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.
The process of removing oxygen from blood or water, basically turning your red stuff blue (or making your aquarium a fish graveyard). In fitness contexts, it's what happens to your blood after your muscles greedily steal all the oxygen during that last brutal set. Think of it as oxygen's eviction notice from your bloodstream.
The nervous system's process of activating muscle fibers to produce force—more technical way of saying 'making your muscles work harder.'
How high up something is, measured from sea level or ground zero. In sports, athletes obsess over this because thin air makes your lungs feel like tiny angry birds.
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?'
The muscle pain and stiffness that peaks 24-72 hours after unfamiliar or intense exercise. The body's passive-aggressive way of reminding you that leg day actually happened.
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.
How quickly you can generate maximum force, essentially your muscles' 0-60 time. Critical for explosive athletes and completely ignored by people who think lifting slowly is somehow superior for building strength.
What happens when your muscles get tired of waiting for oxygen and start producing their own sour battery acid, also known as lactic acid (though technically it's lactate in your bloodstream). This delightful byproduct is what makes your legs feel like they're filled with concrete during intense exercise. Despite its bad reputation, lactate is actually a fuel source your body can use, so it's not the villain everyone makes it out to be.
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.
Having the same osmotic pressure or solute concentration as another solution—typically referring to sports drinks that match your blood's chemistry so your body actually absorbs them. Medical solutions are isotonic when they won't cause your cells to shrivel or explode on contact, which is generally considered desirable. Also describes muscles with equal tension, though that meaning gets way less advertising dollars.
