<reasoning>

Analyze muscular fitness types

The first question asks for the type of muscular fitness developed using less weight and more repetitions.
Using the Muscular Strength vs Endurance knowledge point:

• Muscular strength is the ability to exert maximal force for a short duration (high weight, low repetitions).
• Muscular endurance is the ability of a muscle to sustain repeated contractions over time (low weight, high repetitions).

Therefore, the correct option is "muscular endurance".

Analyze heart disease risk factors

The second question asks what high levels of a substance are frequently related to heart disease.

• Cholesterol, specifically low-density lipoprotein (LDL) cholesterol, builds up in arterial walls, causing atherosclerosis and increasing heart disease risk.
• Endorphins, estrogen, and platelets at normal physiological levels do not share this primary, direct chronic relationship with heart disease risk.

Therefore, the correct option is "cholesterol".

Analyze the benefits of jogging

The third question asks which area of health-related fitness is benefited the most by jogging.

• Jogging is a continuous, aerobic exercise that elevates the heart rate over an extended period.
• This primarily strengthens the cardiorespiratory system, enhancing cardiovascular endurance.

Therefore, the correct option is "cardiovascular endurance".
