High-intensity interval training is making a comeback. Not that it really went anywhere, but it’s definitely taking a firmer place in our training as, these days, many of us need workouts that are fast and effective – like this one. In just 15 minutes this workout will have helped you burn plenty of calories, whilst adding in a pair of dumbbells will challenge your muscles further to help you build some solid gains.
HIIT is well-known for its muscle-building and fat-burning benefits, but this style of training possesses many other advantages too. A study published in the National Library of Medicine revealed HIIT is highly effective at boosting our cardiovascular fitness, more so than traditional endurance training. While another study has shown that doing three HIIT workouts a week can have the same benefits to our blood pressure as those who completed endurance training four times a week. Basically, despite the workouts being short, they pack a punch.
