front 1 Aerobic exercise | back 1 any rhythmic, continuous physical activity that increases your heart rate and breathing, relying on oxygen to meet energy demands |
front 2 Anaerobic exercise | back 2 a high-intensity, short-duration activity that breaks down glucose for energy without using oxygen |
front 3 Cardiovascular endurance | back 3 the ability of the heart, lungs, and blood vessels to efficiently supply oxygen to working muscles during sustained, moderate-to-high intensity physical activity. |
front 4 Circuit Training | back 4 a high-efficiency workout structure involving a series of 5–15 strength and cardio exercises performed in succession with minimal rest (often 0–15 seconds) between them |
front 5 Concentric exercise | back 5 the phase of movement where a muscle shortens under tension to overcome resistance |
front 6 Cool down | back 6 a 5- to 10-minute period of,low-intensity activity following,strenuous exercise that allows the body to gradually transition from high exertion to a resting state |
front 7 Diminishing return | back 7 an economic principle stating that as you increase a single input (like labor or capital) while keeping other factors constant, the incremental output (or benefit) will eventually decrease. |
front 8 Eccentric exercise | back 8 a type of strength training where muscles lengthen while under tension |
front 9 Exercise adaptation | back 9 the body's long-term physiological adjustment to the stress of regular physical activity, resulting in improved structural and functional efficiency |
front 10 Exercise plateau | back 10 a stage in fitness training where progress stalls and performance improvements stop despite consistent effort. |
front 11 Exercise reversibility | back 11 the physiological gains, strength, and endurance achieved through training are lost when a person ceases or significantly reduces their exercise routine |
front 12 F.I.T.T.E. principle | back 12 a structured framework for designing effective fitness programs, standing for Frequency, Intensity, Time, and Type. |
front 13 Flexibility | back 13 the ability of a joint or series of joints to move through a full, pain-free range of motion, influenced by muscles, tendons, ligaments, and skin |
front 14 Heart rate | back 14 the number of times the heart beats per minute (bpm) |
front 15 Muscular contraction | back 15 the physiological process where muscle fibers generate tension and activate, often resulting in shortening, lengthening, or holding a static position |
front 16 Muscular endurance | back 16 the ability of a muscle or group of muscles to repeatedly exert force against resistance—such as weights or body weight—over an extended period without fatiguing |
front 17 Muscular strength | back 17 the maximum amount of force a muscle or muscle group can generate in a single, maximal contraction |
front 18 Overload principle | back 18 to improve strength, endurance, or muscle size, you must subject the body to stress or workloads greater than what it is accustomed to. |
front 19 Plyometrics | back 19 explosive exercises designed to increase muscular power (strength + speed) by forcing muscles to exert maximum force in short intervals. |
front 20 Range of motion | back 20 the full, measurable movement potential of a joint, defining how far and in which direction it can bend, straighten, or rotate. |
front 21 Repetitions | back 21 repeat |
front 22 Warm-up | back 22 stretches or easy workout before an actual workout |
