Training in increases the vascularization of muscle so that more blood can be delivered to the tissue when active. In addition there is an increase in muscle mass, increased ability for metabolism with more myoglobin and more mitochondria in active tissue.
Changes in height during growth spurts. Changes in muscle mass and strength through exercise. Changes in skin elasticity and appearance due to aging. Changes in hair color and texture over time. Changes in weight due to diet and exercise habits. Changes in body shape during puberty and throughout life.
Lifting a dumbbell is considered isotonic exercise because the muscle length changes as the weight is lifted against gravity. Isometric exercise, on the other hand, involves static muscle contractions without changing muscle length.

During exercise muscle cells use oxygen.
Muscle mass fluctuates due to a variety of factors such as diet, exercise, hydration levels, and genetics. Changes in these factors can lead to increases or decreases in muscle mass over time.
To help in muscle recovery by rebuilding damaged muscle tissue from exercise
exercise
Yes. Strenuous exercise can kill the muscle fibers. Such muscle fibers are replaced by fibrous tissue.
The primary muscle intended for exercise.
Yes, exercise is the key to keeping muscle tone. If you lose weight and don't exercise you will also lose your muscle in the process.
Exercise causes your muscle cells to widen and grow so that that muscle becomes bigger and stronger.
The lateral raise exercise primarily targets the deltoid muscle in the shoulder.
