How to live longer: The best exercise for increasing life longevity – what is it?

What is high-intensity interval training (HIIT)

Nuffield Health explains: “HIIT training stands for High Intensity Interval Training – a form of cardiovascular exercise. HIIT can be further broken down into two main categories SIT (sprint interval training) and HIIT (high intensity interval training). 

“SIT is a form of very intense interval training that should only be performed by already well-conditioned people who have no contrary health conditions.

“You perform 3-5 intervals of very short maximal-intensity exercise working until you can’t sustain the intensity, followed by a prolonged recovery period.

“This would typically be 20-30 seconds of work followed by a three to five-minute rest interval.”

HIIT involves exercising from 30 seconds to three minutes, working between 80-100 percent of your maximum heart rate, with shorter recovery periods than SIT.

Nuffield Health continues: “There is no specific formula to HIIT but as a rule of thumb I would recommend your recovery period should be at least the same as your work interval and can become shorter as you get fitter.”
