Hypertrophy
Degredation is greater than synthesis
Atrophy
Allows the joints to move freely, reducing the risk of injury
Flexibility
Supports the ongoing activity of the heart and lungs
Cardiorespiratory endurance
Enables muscles to work harder and longer without fatigue
Muscle strength and muscle endurance
Improves as physical activity supports lean body tissues and reduces excess body fat

Helps build muscle strength, muscle power, and muscle endurance
Resistance training
