The component of fitness are cardiovascular fitness, muscular strength and endurance, flexibility and body composition.

Cardiovascular or aerobic fitness is brisk physical activity that requires the heart and lungs to work harder to meet an increased oxygen demand. Aerobic exercises can be performed at a variety of intensity levels.

• Light Activities: Walking at a leisurely pace or gardening
• Moderate Exercise: Brisk pace walking, leisure swimming, elliptical training, bicycling (less than 12 mph)
• Vigorous Exercise: Basketball, soccer, jogging, racquet sports, fast bicycling

Strength training is building stronger muscles and increasing the amount of time that you can use them. Strength training can be done with or without equipment.

• Equipment: Weight machines, dumbbells, plate weights, resistance tubes, medicine balls
• No Equipment: Body weight exercises, i.e., push ups, sit-ups, lungs, squats

Flexibility is the ability to move joints and muscles through their complete range of motion. Improvements in flexibility can be achieved through stretching or performing routines such as yoga or pilates.

Body composition is best described as the percent of the body that is fat-free tissue. It can be estimated through skinfold measurements, hydrostatic weighing, and biometric impedance to name a few.
