100

This is the classification for a Body Mass Index (BMI) between 18.5 and 24.9, according to the NIH and WHO standards.

What is normal or desirable

100

This stretching technique is often recommended by fitness experts because it is safe and effective, involving a slow stretch held for 10–30 seconds to the point of slight tension or mild discomfort.

What is static stretching?

100

Pitching a softball is an example of this type of flexibility 

 What is dynamic?

100

This is the most significant component of metabolism, accounting for approximately 65–70% of daily energy expenditure

What is Resting Metabolic Rate (RMR) or resting metabolism?

100

This term is defined as having a total body weight above the recommended range for good health, determined by large-scale population surveys

What is overweight?

200

This inexpensive and practical method assesses body composition by measuring the thickness of folds of skin at various sites on the body using a caliper.

What are skinfold measurements?

200

This stretching technique involves movement that is fluid and controlled, moving joints in an exaggerated manner through their range of motion, but without rapid bouncing.

What is Dynamic (Functional) Stretching?

200

 This common ailment is the second most common reason for absences from work and is experienced by more than 85% of Americans by age 50

What is low-back pain?

200
This is a small chamber that uses air displacement to measure body composition.

What is the bod pod?

200

his type of body fat, located around major organs (also known as intra-abdominal fat), is considered more harmful to health than subcutaneous fat

What is visceral fat?

300

The technique of hydrostatic weighing relies on the fact that people with more of this specific tissue float and weigh less underwater, while lean people sink and weigh more.

What is body fat or fat?

300

 This technique, involving rapid, bouncy movements, is usually not recommended for people of average fitness because it can strongly stimulate proprioceptors and may increase the risk of injury

What is ballistic stretching?

300

In addition to reducing muscle cramps and relieving aches, stretching lowers systolic and diastolic blood pressure, reduces arterial stiffness, and improves endothelial function, thereby benefiting the health of these structures

What are blood vessels

300

The carbohydrate-insulin model of obesity suggests that calories consumed from processed carbohydrates and sugar are prime drivers of increases in body fat due to their impact on the levels of this hormone

What is insulin?

300

For women, an extremely low percentage of body fat is associated with loss of bone mass and this condition, defined as absent or infrequent menstruation

What is amenorrhea?
400

This is the maximum recommended waist circumference measurement for males (in centimeters) that is associated with an increased risk of heart disease and diabetes.

 What is 102 cm (or 40 inches)

400

PNF (Proprioceptive Neuromuscular Facilitation) uses reflexes initiated by muscle and joint nerves, often employing the contract-relax method, where this action is performed just before the stretch

What is contracting the muscle?

400

To prevent injury and improve flexibility, stretching exercises should be performed when muscles are in this state

What is warm?

400

 The body tries to conserve energy by lowering the Resting Metabolic Rate (RMR) when there is a decline in this, leading the body to "defend" the original starting weight

What is low-calorie intake and/or weight loss?

400

This disease, which disrupts normal metabolism and causes a buildup of glucose in the bloodstream, is three times more likely to develop in people with obesity

What is diabetes?

500

 A serious weight trainer or athlete who is classified as overweight by the BMI scale would find this classification inaccurate because their "excess" weight is in this specific tissue, which is healthy.

What is muscle or muscle mass?

500

 This type of stretching achieves a greater range of motion, often requiring an outside force like a partner, but carries a greater risk of injury because the muscles themselves do not control the stretch.

 What is passive stretching?

500

This condition, characterized by a rounding of the upper back, can result from prolonged sitting in a slumped position, which leads to tightness in the muscles in the front of the chest

What is kyphosis?

500

People with normal weight differ from those with overweight in the composition of these microorganisms housed in the human intestine, suggesting their involvement in the development of obesity

What is gut microbiota or intestinal flora?

500

This type of muscle fiber, which provides structure and support, is closely intertwined with elastin (yellow fibers that are elastic and flexible) and is a principal type of connective tissue

What is collagen?
