What is High-Intensity Interval Training (HIIT)?

HIIT is doing a set of very hard exercises then resting for a bit. This style is based on the idea that doing short, hard spurts of work, with breaks to catch your breath, can be better than doing less hard stuff for longer. These tough bursts make the body’s energy burning rates go up higher than easy work, helping burn more energy during and after the work out—a thing called the “burn more later” effect.

Perks of HIIT

The gains from HIIT go past just burning calories. It’s shown to boost heart and lung fitness, lower blood sugar, and trim body fat better than other workouts. HIIT also makes heart health better, speeds up metabolism, and makes muscles last longer. It’s so adaptable; workouts can change to suit different fitness levels without needing lots of time.

  • Heart Fitness: Studies show HIIT can make the heart healthier, as well or even better, than long, steady training.
  • Body Changes: HIIT makes muscles better at burning fat and handling sugar, which can help stop or manage type 2 diabetes.
  • Doable and Quick: For busy people, HIIT is a handy way to slip exercise into short time slots, with sessions lasting just 15-30 minutes.

Who Can Try HIIT?

HIIT fits a lot of people, from pro sports folks to the everyday person looking for quick workouts. But, because it’s very hard, people with heart problems or who are at high risk should talk to a doctor before trying HIIT. Also, newbies should start slow and get stronger bit by bit to dodge getting hurt.

The Start of HIIT

HIIT isn’t a new thing but has been around for many years. It got big and got serious study in the 1970s, thanks to Dr. Izumi Tabata, a researcher from Japan. He looked at Olympic speed skaters, creating the “Tabata Routine,” which is 20 seconds of super-hard work, then 10 seconds of rest, doing this non-stop for 4 minutes (or eight times). His work showed how much this training can improve both the heart and lung systems.
