Fitness and Exercise: Health Benefits, How to Get Started, and How to Get Better

Numerous individuals aspire to achieve fitness because, fundamentally, fitness is synonymous with good health.

Maintaining a high level of overall fitness is associated with a reduced risk of chronic diseases and an enhanced ability to effectively manage health challenges. Furthermore, optimal fitness contributes to increased functionality and mobility throughout an individual’s lifespan.

In the short term, engaging in physical activity can significantly impact day-to-day functioning, leading to improvements in mood, focus, and sleep quality.

In essence, our bodies are designed for movement, and they tend to operate more efficiently when we prioritize physical fitness.

It is crucial to recognize that there are diverse approaches to achieving fitness, with distinctions between a ballet dancer and a bodybuilder, or a sprinter and a gymnast. Importantly, fitness does not conform to a singular “look.” In reality, physical appearance alone cannot accurately convey information about someone’s habits, their level of physical activity, or their overall fitness.

Understanding Fitness According to the guidelines outlined by the U.S. Department of Health and Human Services (HHS) in the Physical Activity Guidelines for Americans, there are five key components of physical fitness:

  1. Cardiorespiratory Fitness: This is often measured by your VO2 max, representing your body’s ability to take in and utilize oxygen, crucial for the nourishment of all your tissues. Abbie Smith-Ryan, PhD, professor and director of the Applied Physiology Laboratory at the University of North Carolina in Chapel Hill, emphasizes the direct correlation between cardiorespiratory fitness and overall health and quality of life.
  2. Musculoskeletal Fitness: Encompassing muscle strength, endurance, and power.
  3. Flexibility: Refers to the range of motion of your joints.
  4. Balance: Signifies your ability to maintain stability on your feet and avoid falls.
  5. Speed: Reflects how swiftly you can move.

A widely referenced peer-reviewed research paper from 1985 distinguished between the terms “physical activity” (bodily movement resulting in energy expenditure), “exercise” (planned and structured physical activity), and “physical fitness.” According to this paper, physical fitness is a set of attributes that individuals possess or attain, determining their capacity to perform daily tasks with vigor and alertness, free from undue fatigue. Components such as cardiorespiratory endurance, muscular endurance, muscular strength, body composition, and flexibility are identified as measurable aspects of fitness.

In practical terms, fitness is synonymous with functionality, as stated by Dr. Smith-Ryan. Can you carry groceries or ascend stairs without becoming breathless? Can you engage in playful activities with your children in the backyard? Can you navigate staircases with ease? Fitness, in the real world, translates to the ability to carry out daily tasks with efficiency and vitality.

Exercise differs from fitness as it constitutes the actions taken to enhance one’s overall fitness level.

“Categories of Physical Fitness
Physical fitness encompasses various components crucial for a comprehensive exercise routine, as outlined in the Physical Activity Guidelines for Americans by the U.S. Department of Health and Human Services (HHS). The components emphasized for weekly exercise include:

Aerobic (Cardiovascular) Exercise:

  • Enhances heart rate and breathing rate.
  • Examples: brisk walking, running, cycling, swimming, aerobic fitness classes, tennis, dancing, yard work, and jumping rope.

Strength Training

  • Improves mobility, muscle strength, endurance, and power.
  • Activities: lifting weights, using resistance bands or body weight, carrying heavy loads, and strenuous gardening.

Flexibility and Mobility:

  • Focus on joint range of motion.
  • Flexibility involves tendons, muscles, and ligaments’ ability to stretch, while mobility pertains to the body’s joint movement capacity.


  • Ensures stability to prevent falls.
  • Essential for older adults.


  • Measures how quickly one can move.

In addition to these, other components like endurance, muscular endurance, power, and agility are recognized. Fitness should be viewed as functional, ensuring individuals can perform daily tasks with vitality and alertness without excessive fatigue.

Understanding Exercise, Fitness, and Physical Activity
Distinguishing between “physical activity,” “exercise,” and “physical fitness” is vital. Physical activity encompasses bodily movement resulting in energy expenditure, while exercise refers to planned and structured physical activity. Physical fitness, according to a 1985 research paper, includes attributes determining one’s ability to carry out daily tasks with vigor and alertness.

The Real-World Impact of Fitness
Fitness directly translates to functional abilities in real life. For instance, the ability to carry groceries, climb stairs without exhaustion, or engage in recreational activities showcases fitness translating into practical functionality.

The Significance of Rest and Recovery
Building in rest and recovery days is crucial for the body to repair and recover from exercise-induced stress. Exercise puts stress on muscles and the body, and adequate rest fosters the healing process, promoting strength and fitness.

Health Benefits of Exercise
Regular exercise substantially reduces the risk of chronic diseases such as heart disease, type 2 diabetes, and cancer. It contributes to mental well-being, with notable benefits including:

  1. Improved Mood: Acts as a buffer against depression and anxiety.
  2. Better Sleep: Facilitates restful sleep and positively influences sleep quality.
  3. Long-Term Health: Enhances brain and bone health, preserves muscle mass, and reduces the risk of various diseases.

Fitness Aids in Chronic Disease Management
Exercise helps manage chronic health issues like osteoarthritis, high blood pressure, diabetes, multiple sclerosis, Parkinson’s disease, dementia, stroke, and cancer. It improves pain management, insulin sensitivity, heart health, and mental well-being.

Recommended Exercise Guidelines
According to the Physical Activity Guidelines for Americans, achieving either 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity aerobic activity weekly promotes good health. Muscle-strengthening activities for major muscle groups are recommended at least twice a week.

Balancing Act: Fueling Your Body
Proper nutrition complements exercise. Pre-workout, easily digestible carbohydrates like a banana or cereal fuel short-term energy needs. During prolonged exercise, consume 30 to 60 grams of carbohydrates per hour after the initial 60 minutes. Post-workout, refuel with a balanced intake of carbohydrates and protein.

Tips for Initiating and Sustaining Exercise:

  1. Break It Up: Accumulate activity throughout the day.
  2. Increase Gradually: Begin at a comfortable level and progress slowly.
  3. Incorporate ‘Non’-Exercise Exercise: Daily activities count toward movement goals.
  4. Schedule It: Treat exercise as a nonnegotiable activity and schedule it.
  5. Consider HIIT: High-intensity interval training is effective and adaptable.
  6. Phone a Friend: Partnering with someone enhances motivation and consistency.

Home Gym Equipment Considerations:
Home workouts offer convenience, and a variety of online resources provide exercise programs. Body-weight exercises, yoga mats, resistance bands, or dumbbells can suit different preferences, budgets, and spaces. Tailor choices based on personal needs and goals.”
