What is Interval Training?

Interval training is a type of workout. It alternates between high-intensity exercise periods and low-intensity recovery periods. High-intensity exercise means pushing yourself hard. Low-intensity recovery means taking it easier for a while. This method challenges your body to work harder than during steady-state cardio. Steady-state cardio is exercising at a continuous pace. Interval training helps you improve fitness in less time.

Key Components of Interval Training:

  1. Work intervals: Short bursts of high-intensity exercise
  2. Recovery intervals: Periods of lower-intensity activity or rest
  3. Repetitions: The number of times you repeat the work-recovery cycle

The Science Behind Interval Training

Interval training works by pushing your body to its limits during the high-intensity periods. This effort triggers several physiological changes in your body.

Physiological adaptations refer to how your body changes to cope with the new stress. These changes can include improvements in your muscles, heart, and lungs.

  1. Increased VO2 max: Your body’s ability to use oxygen during exercise improves
  2. Enhanced fat burning: High-intensity exercise boosts your metabolism and increases fat oxidation
  3. Improved insulin sensitivity: Helps regulate blood sugar levels more effectively
  4. Increased mitochondrial density: More energy-producing structures in your cells

Benefits of Interval Training

Incorporating interval training into your fitness routine can lead to numerous benefits, including:

  1. Time-efficient workouts: Achieve better results in less time
  2. Improved cardiovascular health: Strengthens your heart and lungs
  3. Increased fat loss: Burns more calories during and after exercise
  4. Enhanced endurance: Boosts your stamina for other activities
  5. Preserved muscle mass: Helps maintain lean muscle while losing fat
  6. Reduced boredom: Adds variety to your workout routine
  7. No equipment necessary: Can be done with bodyweight exercises or minimal equipment

Types of Interval Training

There are several popular forms of interval training:

1. High-Intensity Interval Training (HIIT)

HIIT involves short bursts of maximum effort, followed by brief recovery periods. A typical HIIT workout might include:

  • 30 seconds of all-out effort
  • 30 seconds of rest or low-intensity exercise
  • Repeat for 15-20 minutes

2. Tabata Training

Developed by Japanese researcher Dr. Izumi Tabata, this method involves:

  • 20 seconds of maximum effort
  • 10 seconds of rest
  • Repeat for 4 minutes (8 rounds total)

3. Fartlek Training

Swedish for “speed play,” Fartlek training involves alternating between fast and slow speeds during a continuous run.

4. Sprint Interval Training (SIT)

SIT involves short, all-out sprints followed by longer recovery periods. A typical SIT workout might include the following:

  • 30 seconds of maximum sprint
  • 4 minutes of rest or very low-intensity exercise
  • Repeat 4-6 times

Getting Started with Interval Training

If you’re new to interval training, follow these steps to get started safely:

  1. Consult your doctor: Especially if you have any health concerns or are new to exercise
  2. Start with a proper warm-up: 5-10 minutes of light cardio and dynamic stretching
  3. Begin with longer intervals: Start with 1-2 minutes of higher intensity, followed by equal rest periods
  4. Choose appropriate exercises: Begin with familiar exercises like jogging, cycling, or bodyweight movements
  5. Listen to your body: Stop if you feel dizzy, nauseous, or experience pain
  6. Cool down and stretch: End your workout with 5–10 minutes of light activity and static stretching

Incorporating Interval Training into Your Fitness Routine

For the best results, try to include 1-3 interval training sessions each week. This depends on your fitness level and goals. Mix these sessions with steady-state cardio. Steady-state cardio means exercising at a constant pace. Add strength training and rest days, too. This combination makes for a balanced fitness program.
