A cheat sheet to decode gym lingo and wellness trends
Navigating the modern fitness world can sometimes feel like trying to learn a whole new language, leaving you scratching your head at the juice bar. Whether you’ve heard influencers raving about tracking Macros, optimizing high volume foods, or diving into the science of GLP-1, it’s easy to get overwhelmed by all the buzzwords. From intense workout protocols like EMOM, AMRAP, and HIIT, to contrasting dietary lifestyles like Keto and Carnivore, our ultimate wellness dictionary breaks it all down. We’re diving deep into the physiological differences between aerobic and anaerobic training, settling the debate between classic Callanetics and gravity-defying Calisthenics, and exploring how cutting-edge biohacking can optimize your daily routine. Consider this your cheat sheet to decoding gym lingo and wellness trends so you can crush your health goals with total confidence!
Diet
Calorie — A calorie is a unit of energy that measures how much fuel food and drinks provide to your body — and understanding how many calories you consume versus how many you burn is one of the foundational principles of weight loss, weight gain, and weight maintenance.
- One pound of body fat contains approx. 3,500 calories
- TDEE — Short for “Total Daily Energy Expenditure,” this is an estimation of the total number of calories your body burns in a 24-hour period based on your age, height, weight, gender, and activity levels. It factors in your baseline metabolism alongside daily movement, making it the foundational number you need to determine how many calories to eat for weight loss, muscle gain, or maintenance.
Carbohydrates — Often called carbs, these are your body’s primary and preferred energy source. Found in everything from fruits and veggies to grains and sweets, they break down into glucose to fuel your daily activities, intense workouts, and brain function.
Diet — Referring to the specific foods and beverages a person habitually consumes, this term defines your overall, long-term pattern of nutrition rather than just a temporary restriction. While often associated with short-term weight loss programs, a well-balanced diet serves as the foundational fuel your body needs to support energy levels, health, and fitness goals.
Carnivore Diet — An extremely restrictive diet consisting solely of animal products like meat, fish, and eggs, eliminating all plant-based foods entirely.
Keto Diet— A very low-carb, high-fat diet that shifts your body into ketosis, a metabolic state where it burns fat for fuel instead of carbohydrates.
Fats — Fats aren’t all created equal, which is why we break them down into distinct categories based on their chemical structure—ranging from heart-healthy unsaturated options to processed trans fats that are best avoided.
- Monounsaturated Fats (Healthy Fats) — This is a type of healthy, unsaturated fat that is liquid at room temperature but starts to solidify when chilled. Found in delicious staples like avocados, olive oil, and almonds, these fats are famous for supporting heart health and helping to manage cholesterol levels.
- Polyunsaturated Fats (Healthy Fats) — Another powerhouse healthy fat, these contain essential fatty acids like Omega-3s and Omega-6s that your body can’t make on its own. Found in fatty fish (like salmon), walnuts, and flaxseeds, they are incredible for boosting brain function and reducing inflammation.
- Saturated Fats (Less Healthy Fat) — These are fats that are typically solid at room temperature and are mostly found in animal products like butter, cheese, and red meat, as well as coconut oil. While your body needs them in moderation, consuming them in high amounts can drive up bad cholesterol, so it’s best to enjoy them mindfully.
- Trans Fats (Less Healthy Fat) — These are artificial fats created through an industrial process that adds hydrogen to liquid vegetable oils to make them shelf-stable. Found in many packaged baked goods, fried foods, and processed snacks, they offer no nutritional value and are widely considered the least healthy option for your heart.
GLP-1 — A class of medications (like Ozempic and Wegovy) that mimic a naturally occurring hormone to regulate blood sugar and appetite, widely used for diabetes management and weight loss.
High volume foods — These are foods that let you eat larger portions for fewer calories, typically due to high water and fiber content (think leafy greens, berries, and broth-based soups) — perfect for staying full while in a calorie deficit.
Macros — What is a macro? Short for macronutrients (protein, carbs, and fats), macros refer to the three nutrient categories that make up your caloric intake and play a huge role in body composition and energy.

Fitness
Aerobic — Aerobic exercise is sustained, oxygen-dependent activity like running, cycling, or swimming that improves cardiovascular endurance over time.
Anaerobic — Anaerobic exercise involves short, intense bursts of effort (like sprinting or weightlifting) that don’t rely on oxygen for energy and build strength and power.
AMRAP — Short for “As Many Rounds (or Reps) As Possible,” this is a workout format where you complete as many rounds or reps of an exercise as you can within a set time frame.
Body Recomp – Short for body recomposition, body recomp is the process of simultaneously losing fat and gaining muscle at the same time — essentially changing the ratio of fat to muscle in your body without necessarily seeing a dramatic change on the scale. It’s the reason the scale might stay the same while your clothes fit completely differently and your body looks and feels entirely transformed.
Calisthenics — A form of strength training that uses your own bodyweight (think push-ups, squats, and pull-ups) rather than equipment to build muscle and endurance.
Callanetics — A low-impact exercise method using small, controlled, pulsing movements designed to target and tone deep muscle groups.
EMOM — Short for “Every Minute on the Minute,” this workout format has you performing a set exercise at the start of each minute, resting for whatever time remains before the next minute begins.
HIIT — High-Intensity Interval Training alternates short bursts of intense exercise with brief recovery periods, maximizing calorie burn and cardiovascular benefits in a shorter amount of time.
Progressive Overload – Progressive overload is the fundamental principle of strength training that involves gradually increasing the demands placed on your muscles over time — whether through adding more weight, more reps, more sets, or less rest between sets. It’s the reason your body keeps changing and getting stronger rather than plateauing, and it’s the secret weapon behind every truly effective long-term fitness program.
Misc.
BMI — Short for “Body Mass Index,” this is a simple numerical calculation that estimates your body fat category based on your height and weight. It is widely used as a quick screening tool to categorize individuals as underweight, normal weight, overweight, or obese, though it does not distinguish between muscle mass and fat.
BMR — Short for “Basal Metabolic Rate,” this is the minimum number of calories your body needs to perform basic, life-sustaining functions—like breathing, circulating blood, and regulating temperature—while at complete rest. It represents your baseline energy expenditure before accounting for any daily movement or exercise.
Biohacking — The practice of using science, technology, and lifestyle tweaks (like cold plunges, red light therapy, and nutrient tracking) to optimize your body’s performance, longevity, and overall wellness.
