No pain, no gain, no idea what half these terms mean.
The most feared day in the gym calendar, responsible for more canceled plans than any holiday. Skipping it is the fitness world's original sin, yet somehow everyone's legs look suspiciously fresh on Monday morning.
The act of repeatedly hoisting heavy objects for the express purpose of creating microscopic muscle tears that supposedly make you stronger. In gym culture, this has evolved into an entire lifestyle complete with its own vocabulary, protein shake requirements, and unspoken rules about reracking weights. Also used as a verb by people who make going to the gym their entire personality.
Exercises involving walking while carrying heavy objects in various positions, the functional fitness equivalent of helping your friend move furniture but calling it training. Surprisingly effective for building strength and questioning your gym bag contents.
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.
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 speed at which you perform each phase of an exercise, usually written as a sequence like '3-1-2-0' representing eccentric-pause-concentric-pause in seconds. It turns simple lifting into a mathematical equation that most people promptly ignore.
The variables that define a training session: sets, reps, weight, rest periods, and tempo. The recipe for gains that everyone tweaks based on Instagram advice.
A hopelessly devoted LeBron James fanatic who treats every word from King James as gospel, regardless of logic or evidence. These fans possess an Olympic-level ability to justify any on-court performance, even when LeBron shoots like he's wearing oven mitts. Facts and statistics bounce off them like basketballs off a backboard.
Walking while holding heavy objects in various positions (farmer's carries, suitcase carries, etc.). Simultaneously functional and humiliating.
The primal fitness philosophy that strength training should focus on compound movements with substantial weight. Caveman approach to fitness that actually works surprisingly well.
A siren system at Planet Fitness that sounds when someone grunts too loudly, drops weights, or otherwise exhibits behavior deemed too 'gymtimidating'—essentially a panic button for people afraid of effort sounds.
