The rewards of improved health, increased energy, and physical performance will make the effort well worth it.

What Is HIIT (High-Intensity Interval Training)?

What Is HIIT (High-Intensity Interval Training)?

High-intensity interval training (HIIT) is a training technique in which you give all-out, one hundred percent effort through quick, intense bursts of exercise, followed by short, sometimes active, recovery periods. This type of training gets and keeps your heart rate up and burns more calories in less time.

  • HIIT workouts typically last 10 to 30 minutes and consist of short periods of intense exercise followed by recovery periods. For example, sprinting for 1 minute and then jogging for 2 minutes.
  • HIIT can be applied to many types of exercises, including running, biking, swimming or strength training with weights. The possibilities are endless.
  • During the intense intervals, aim for 70 to 95 percent of your maximum heart rate. The recovery periods should allow your heart rate to return to 50 to 70 percent of your maximum.
  • HIIT improves your cardiovascular fitness and metabolism, burns more calories and builds strength. Studies show HIIT can significantly improve your aerobic and anaerobic capacity.
  • To get started with HIIT, choose an exercise you enjoy, like running, biking or rowing. After properly warming up, go all out for 1 to 2 minutes, then recover for 1 to 2 minutes. Repeat this interval circuit 3 to 4 times, 2-3 times a week. You can then build up the intensity and duration over time as your endurance improves.

HIIT is a very efficient way to exercise and an effective training method for both cardio and strength. By pushing yourself during the intense intervals, you can achieve health benefits in less time. However, HIIT may not suit everyone and you should talk to your doctor first, especially if you have any medical conditions.

The Benefits of High-Intensity Interval Training

High-intensity interval training (HIIT) offers significant benefits for both cardiovascular and metabolic health. Studies show HIIT can:

•Improve aerobic and anaerobic capacity. HIIT involves short periods of intense exercise followed by recovery periods. This helps increase your endurance and ability to sustain high-intensity activity.

•Burn more calories. HIIT causes an oxygen deficit that increases your metabolism for hours after exercise. This “afterburn effect” helps you burn more calories, even at rest.

•Build muscle. The intense intervals promote muscle gain by requiring your muscles to adapt to the increased demands. Studies show HIIT leads to greater gains in both cardiovascular fitness and muscle strength.

•Improve insulin sensitivity. HIIT helps cells become more responsive to insulin, which is important for blood sugar control and fat loss. Improved insulin sensitivity means your body is better able to utilize blood glucose and less likely to store it as fat.

•Reduce health risks. HIIT exercise provides cardiovascular benefits that can lower health risks like heart disease. It helps lower blood pressure and cholesterol levels while improving circulation and respiratory health.

•Shorten workouts. HIIT workouts are time-efficient, often lasting just 15-30 minutes. The short, intense intervals provide an efficient way to exercise and reap benefits, even with a packed schedule.

In summary, HIIT offers an array of benefits for health, fitness, and metabolism. By incorporating high-intensity interval training into your routine, you can achieve more in less time and experience life-changing results. The rewards of HIIT are well worth the effort.

A Beginner’s Guide to HIIT Workouts

To get started with HIIT workouts, follow these steps:

Choose an exercise modality. The options for HIIT workouts are endless. You can do bodyweight exercises like pushups, squats, and burpees. You can utilize equipment like a jump rope, exercise bike, or rowing machine. Or you can do weighted exercises with dumbbells or kettlebells. Pick exercises you enjoy and that match your fitness level.

Start with a warm-up. Do 5 to 10 minutes of light cardio like jogging in place or jumping jacks to raise your heart rate and warm up your muscles. This will prepare you for the intense intervals to come.

Determine your interval times. For beginners, a good place to start is 30 seconds of high intensity exercise followed by 30 seconds of recovery. You can adjust the times up or down from there based on your needs. The shorter the high intensity interval, the higher the intensity needs to be.

Include rest periods. In between intervals, do an active recovery like walking or lightly jogging in place. This helps your heart rate come back down before the next high intensity interval. The rest periods should be the same time or slightly longer than your high intensity intervals.

Start with a shorter duration. If you’re new to HIIT, aim for 10 to 15 minutes of intervals including warm-up and cool-down. You can build up the duration over time as your endurance improves. The total workout time including warm-up and cool-down should be 20 to 30 minutes.

Cool down properly. Do 5 to 10 minutes of light cardio and stretching. This helps your breathing and heart rate return to normal and prevents dizziness or nausea. Stretching also aids muscle recovery.

With practice and progression, you’ll be performing longer, more advanced HIIT workouts in no time. The key is to start slowly, listen to your body, and have fun with it! HIIT workouts provide an efficient way to improve your endurance and burn calories.


As you’ve learned, HIIT is a highly effective and time-efficient form of exercise that provides impressive fitness and health benefits. By incorporating high-intensity interval training into your workout routine, you’ll boost your metabolism, increase your endurance, and burn more calories in less time. The key is pushing yourself outside of your comfort zone for short periods, then recovering and repeating. Start slowly and build up as your fitness improves. With consistency and the right plan for your needs and abilities, you’ll be well on your way to achieving your health and fitness goals through the power of HIIT. The rewards of improved cardiovascular health, increased strength and stamina, and a leaner body are worth the effort. You can do this! Commit to HIIT and start reaping the benefits today. Read more
