HIGH INTENSITY INTERVAL TRAINING (HIIT)

What Is HIIT?

HIIT (High-Intensity Interval Training) is a workout method where short bursts of intense exercise are alternated with brief recovery periods. This cycle is repeated multiple times, making it one of the most time-efficient ways to burn calories and improve fitness.

Example:

• 30 seconds sprint
  
  

• 1-minute walk
  
  

• Repeat for 8–10 rounds
  
  

 Key Point: HIIT burns more calories in less time and is far more effective than steady-state cardio.

Benefits of HIIT: Why You Should Try It

1. Burn More Calories in Less Time
   🔥 HIIT can burn up to 3x more calories compared to steady-state cardio.
   Just 20–30 minutes of HIIT = hours of running or cycling.
   
   

2. Boost Metabolism with the Afterburn Effect (EPOC)
   After a HIIT workout, your body continues burning extra calories for 6–24 hours.
   This is known as Excess Post-Exercise Oxygen Consumption (EPOC).
   
   

3. Lose Fat While Preserving Muscle
   HIIT reduces body fat but helps retain lean muscle.
   Unlike steady cardio, which may cause muscle loss, HIIT protects muscle mass.
   
   

4. Improve Heart & Lung Health
     Lowers blood pressure
     Strengthens the heart
     Enhances lung capacity
   
   

5. Enhance Oxygen Consumption (VO2 Max)
   Increases the body’s ability to use oxygen.
   Higher VO2 Max = better stamina for running and sports.
   
   

6. Regulate Blood Sugar & Improve Insulin Sensitivity
   🩸 Balances blood sugar levels
   🛡 Reduces the risk of type 2 diabetes
   
   

How Does HIIT Work?

• High-Intensity Phase: Pushes the body’s energy systems to the limit.
  
  

• Recovery Phase: Even when the heart rate comes down, the body continues burning calories due to EPOC.
  
  

HIIT Duration & Frequency

• Duration: 15–30 minutes is enough
  
  

• Frequency: 2–3 sessions per week
  
  

• Rest: At least 24 hours between sessions
  
  

⚠️ Pro Tip: Too much HIIT can cause overtraining or injury.

Beginner’s Corner 

If you’re just starting out:

• Begin with light HIIT (e.g., jogging + walking) for 10–15 minutes
  
  

• Focus on consistency over intensity
  
  

• In the first month, stick to 2 sessions per week
  
  

 Once comfortable, try advanced moves like jump squats, burpees, and mountain climbers.

Real-World Example

Sarah, a 35-year-old professional, managed to stay fit despite her busy schedule by doing just 20-minute HIIT sessions, 3 times per week. Within weeks, she lost fat, toned her muscles, and boosted her energy levels.
