Old-fashioned cardio takes hours for results and you easily get bored of the repetitive motion on the treadmill. On the other hand, HIIT is fun, with more variety and engaging movement.
Efficient.
HIIT lasts only 30 minutes, but the after-burn effects will last hours after the exercise.
Minimalistic.
You don't need expensive equipment to do them. Just use your bodyweight, maybe a few dumbbells, a jump rope... That's it!
Location-independent.
You can perform the workouts anywhere! Do it in the living room with your kids, do it in your office on lunch break. If you're daring enough, do it at the side of the road when you're stuck in a traffic jam! (But please don't disrupt the traffic).
A brain booster.
HIIT has been shown to boost levels of brain-derived neurotrophic factor(BDNF), a protein involved in brain-cell repair, learning, memory, mood regulation and cognitive function. Conventional exercising methods do not release this brain-boosting protein.
