75 minutes
people who meet the guidelines for exercise time per week are:
at lower risk of heart disease, type 2 diabetes, breast cancer, and colon cancer
moderate-intensity activity
activity that noticeably accelerates the heart rate and causes you to break a sweat
vigorous-intensity activity
causes rapid breathing and a substantial increase in heart rate
cardiorespiratory fitness
the ability of the heart and lungs to effectively deliver oxygen and nutrients to the body’s muscles and cells via the bloodstream
cardio fitness is developed by:
activities that use the large muscles of the body in continuous movement, such as jogging, running, cycling, swimming, cross-country skiing, and aerobic dance
cardiorespiratory training
improves muscle and liver functioning, and decreases resting heart rate, resting blood pressure, and heart rate at any work level

muscular fitness has two main components:
muscular strength, and muscular endurance
muscular strength
the capacity of a muscle to exert force against resistance
muscular endurance
the capacity of a muscle to exert force repeatedly over a period of time, or to apply and sustain strength for a period lasting from a few seconds to a few minutes
elliptical machines

a treadmill’s surface
designed to cushion compression force, but the device is still an injury risk for people with joint disorders since it facilitates a weight-bearing exercise
