No pain, no gain, no idea what half these terms mean.
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.
A Swedish training method mixing continuous running with random speed intervals. Literally translates to 'speed play,' which sounds much more fun than it actually is.
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.
Training designed to improve the efficiency of energy systems through high-intensity work with short rest. CrossFit's academic-sounding justification for making you do burpees until you see the light.
The addictive pursuit of that temporary muscle swelling and tightness achieved during resistance training. Like a drug habit, but legal and you can see your veins better.
Starting a race or workout at an unsustainably fast speed that feels great for about three minutes before your body stages a full rebellion. The athletic equivalent of financial irresponsibility.
An advanced training system rotating multiple variations of core lifts to develop strength through constant variety rather than linear progression. The Russian roulette of powerlifting programs.
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.
The strategic manipulation of training variables to achieve maximum performance on a specific date—usually competition day. The art of timing your fitness peak instead of accidentally peaking three weeks too early.
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.
A training technique where you perform a set to failure, rest briefly (10-30 seconds), then continue for additional reps. It's the workout equivalent of a horror movie where the monster keeps coming back just when you thought it was over.
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.
General Physical Preparedness—the development of broad fitness attributes and work capacity that support specific training. It's the vegetables of your training diet: unsexy, often ignored, but probably what you actually need.
The pre-workout ritual where you contort your body into various shapes while pretending it prevents injury, or the deliberate elongation of skeletal muscles to improve flexibility and reduce the feeling of being a rusty tin man. Despite decades of debate, the science on whether stretching actually prevents injuries remains hilariously inconclusive. What's certain is that skipping it guarantees you'll feel 85 years old the next morning.
The sacred ritual of preparing your body for actual exercise, involving stretches, light cardio, and usually some complaining about having to be at the gym in the first place. It's that annoying but necessary period where you trick your muscles into thinking they're about to do something athletic. Skip it and your body will absolutely take revenge on you tomorrow.
The training law stating you get good at what you actually practice, meaning endless bicep curls won't magically improve your marathon time. It's fitness's way of saying 'be realistic about cause and effect.'
The phenomenon where concurrent endurance and strength training can compromise gains in both modalities, because your body isn't a limitless adaptation machine. It's biology's version of 'you can't have your cake and deadlift too.'
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.
A competitive sport where the goal is to sculpt your muscles into such cartoonish proportions that you need to turn sideways to fit through doorways. Participants spend years eating chicken breast and lifting heavy things repeatedly, all to be judged on whose muscles look the most aesthetically pleasing while slathered in bronzer. It's basically professional muscle modeling with a side of extreme dedication.
A bench press grip variation where the thumbs remain on the same side as the fingers rather than wrapping around the bar. Named with complete honesty about the potential consequences of this questionable decision.
A plyometric exercise involving jumping onto an elevated platform, testing explosive power and your insurance coverage. Looks impressive until you discover shin-meets-box failure videos.
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.
The actual load used for prescribed training sets, excluding warm-up sets and maximal attempts. The weight where the real work happens and excuses stop working.
The target number of repetitions prescribed for a set, theoretically corresponding to specific adaptations. 1-5 for strength, 6-12 for hypertrophy, 15+ for endurance - or so the legend goes.
