(of body tissue or an organ) waste away, especially as a result of the degeneration of cells, or become vestigial during evolution.

Cardiovascular endurance, or aerobic fitness, is how well your heart and lungs can supply the oxygen you need while you exercise at medium to high intensity. If you have good cardiovascular endurance, you can exercise at medium intensity for a long time (and high intensity for a while) before it makes you tired.Feb 21, 2023

Cooling down is the transition from intense physical activity to a more typical activity level. Depending on the intensity of the exercise, cooling down after a workout method, such as intense weightlifting, can involve a slow jog or walk. Cooling down allows the heart rate to return to its resting rate

Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise.

Diminishing returns is an idea, or situation, that anyone who has trained for a while will most likely encountered. It means that you no longer receive the same progress or growth from the workout or exercise that you have been doing.

For moderate-intensity physical activity, your target heart rate should be between 64% and 76%^{1 , 2} of your maximum heart rate. You can estimate your maximum heart rate based on your age. To estimate your maximum age-related heart rate, subtract your age from 220.

A plateau is a leveling off of your strength progress that occurs around 4-6 months into a routine. It is important not to give up on a routine too quickly because success might not immediately be seen. Steps to overcome a plateau: ✓ Change the intensity of your workout.

What are plyometrics? Plyometric training involves short, intense bursts of activity that target fast-twitch muscle fibers in the lower body. These fibers help generate explosive power that increases speed and jumping height.Aug 2,

Range of motion is the capability of a joint to go through its complete spectrum of movements. It can be passive or active. Passive range of motion can be defined as what is achieved when an outside force, such as a therapist, causes movement of a joint. It is usually the maximum range of motion.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

Warming up' is a part of stretching and preparation for physical exertion or a performance by exercising or practicing gently beforehand, usually undertaken before a performance or practice. Athletes, singers, actors and others warm up before stressing their muscles.
