Core Components of Fitness πŸƒπŸΌβ€β™€οΈπŸ’ͺ🏻

  • Cardiovascular Endurance
  • Muscular Strength and Endurance
  • Flexibility
  • Body Composition

What Is Cardiovascular Fitness?

Cardiovascular endurance is your heart and lungs' ability to deliver oxygen to working muscles during sustained activity. It measures your stamina: how long you can keep going before fatigue sets in.

What is the recommended amount of cardio each week?
150-300 Minutes

Health professions recommend 150-300 minutes of moderate-intensity exercise, or 75-150 minutes of vigorous-intensity exercise, each week!

There are many incredible benefits to a strong cardiovascular fitness level including, a reduced risk of heart disease, stroke, depression, and dementia. Additionally, overtime your mood can improve and your quality of sleep can appear better within a few weeks of exercising.

Some common forms of cardiovascular fitness include:

  • brisk walking
  • dancing
  • jump roping
  • running
  • swimming
  • biking

What Is Muscular Strength and Endurance?

Muscular strength is the maximum force a muscle (or group of muscles) can produce in a single effort. Strength supports posture, helps protect joints, and supports bone health.

You can improve your muscular health by strength training with a progressive overload β€” gradually increasing the weight, reps, or difficulty of an exercise over time. Remember rest is equally as important when strength training, but it is recommended to strength train 2-3 days per week.

What is the recommended length of a strength session?
20-30 Minutes

Mayo Clinic recommends two to three 20-30 minute sessions each week.

What Is Flexibility in Fitness?

Flexibility is the range of motion available at a joint during a movement. It helps make everyday activities easier: maintaining a good balance, bending over, etc.

In general, flexibility helps support more comfortable movement and reduces stiffness that can build up from sedentary habits.

Activities such as yoga, gymnastics, dance, and martial arts are great ways to improve your flexibility!

What Is Body Composition?

Body composition is the ratio of body fat to lean tissue an individual has. It is a great indicator of one's health and is more helpful than body weight alone. It is directly influenced by the other three components, and a good body composition is known to reduce many harmful health conditions.

Body mass index (BMI) is a common measurement of body composition because it is quick and requirements no equipment.

If you are looking to improve your body composition, the most effective way is to improve both your training and nutrition. There is no perfect approach, but a mix a strength training, cardio, and nutrition is a solid starting point.
