An exercise health is a condition of health
which is affected by involvement in physical
exercise.
Our health is dynamic where we can see ups
and downs in its level. Involvement in
physical exercise also plays the important
role in making our health level up and
down.
When we study exercise health education, it
will help us to make proper choices of
physical activities according to our body
composition and nature of the work we are
involved in.

Definition
Muscle work against resistance that
improves strength and endurance
–Strength allows us to move, and
endurance allows us to perform work over
time
Muscles = 40% of our lean body mass
Use it or lose it: unused muscle disappears
(atrophy)
Free Weights
– use of dumbbells and/or bars with weights on
the ends
– involves balance and coordination; useful for
enhancing function in daily activities and
recreational sports

variety of exercises that work several muscle
groups together
Your body, your weight

its range of motion
