Adaptation exercise

when you do new exercises or load your body in a different way, your body reacts by increasing its ability to cope with that new load

Aerobic exercise

physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process

Anaerobic exercise

any exercise that doesn't use the oxygen in your body as its main source of energy

Cardiovascular endurance

how well your heart and lungs can supply the oxygen you need while you exercise at medium to high intensity

Cool down

to bring the body back to its normal physiological level after fast, vigorous exercise or activity by gradually slowing the pace of activity or by doing gentle exercises or stretches

Delayed onset muscle soreness (D.O.M.S)

a sore, aching, painful feeling in the muscles after unfamiliar and unaccustomed intense exercise

Diminishing return

you no longer receive the same progress or growth from the workout or exercise that you have been doing

Eccentric exercise

a type of strength training that involves using the target muscles to control weight as it moves in a downward motion

Exercise heart rate

between 64% and 76%^{1 , 2} of your maximum heart rate

Exercise plateau

a leveling off of your strength progress that occurs around 4-6 months into a routine

F.I.T.T.E. principle

Frequency, Intensity, Time, and Type

Flexibility

the quality of bending easily without breaking.

H.I.I.T. training

High-intensity interval training is a training protocol alternating short periods of intense or explosive anaerobic exercise with brief recovery periods until the point of exhaustion

Isometric exercise

an exercise involving the static contraction of a muscle without any visible movement in the angle of the joint

Muscular atrophy

the decrease in size and wasting of muscle tissue

Muscular contraction

characterized by constant muscle tension with a change in muscle length

Muscular endurance

the ability to continue contracting a muscle, or group of muscles, against resistance, such as weights or body weight, over a period of time

Muscular hypertrophy

increasing muscle size, typically through strength training

Muscular strength

the amount of force you can put out or the amount of weight you can lift

Overload principle

in order to progress and improve, putting the body under additional stress beyond what is normal is key

Plyometrics

exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength)

Range of motion

the extent or limit to which a part of the body can be moved around a joint or a fixed point

Repetitions

the action of repeating something that has already been said or written.

Resting heart rate

60 to 100 beats per minute

Warm-up

prepare for physical exertion or a performance by exercising or practicing gently beforehand.
