What is HIIT?

So, what exactly is HIIT? In a nutshell, it’s a workout style where you push hard for a short burst, catch your breath, then go again. Most HIIT sessions are over in 10 to 30 minutes, making them perfect for anyone short on time. Here are a few reasons people love it:

  • Time-Saving: You can get a killer workout in just 15 minutes. Whether you’re sprinting, cycling, or doing bodyweight moves, HIIT packs a punch without eating up your day.

  • Burns Calories Even After You’re Done: Thanks to the “afterburn” effect, your body keeps torching calories long after you’ve finished sweating.

  • Heart Health: HIIT gets your heart pumping and helps keep it strong—think of it as a tune-up for your cardiovascular system.

  • Run Faster, Longer: Runners love HIIT because it helps them go faster and farther by training muscles to handle tough bursts and recover quickly.

  • Boosts Your Mood: There’s real evidence HIIT can help ease anxiety and depression by ramping up feel-good brain chemicals.

  • Better Sleep: People who do HIIT often find they sleep more soundly and wake up feeling refreshed.

Practice HIIT Everywhere

Many HIIT routines require minimal to no equipment, making them perfect for individuals who prefer to exercise at home, out in the nature or at the local leisure centre. Bodyweight exercises such as squats, lunges, burpees, and mountain climbers can be combined into a high-intensity circuit that targets multiple muscle groups and elevates the heart rate.
