It feels like conventional exercise methods just don’t cut it anymore.

2015 has been proclaimed the “Year of Rucking “, prancercise, doga ( yoga with your dog) and cycle karaoke are all real things and The Glow team have already tried their hand at roller skating and dancing like Beyonce to keep fit.

Now there’s another new method invading your workout and it takes its inspiration from an unusual place: Vikings. Icelandic Vikings to be exact.

Founded by Icelandic personal trainer Svava Sogbertsdottir, The Viking Method is an intense, no-nonsense fitness plan that celebrities including Suki Waterhouse and Nicole Sherzinger swear by. (Post continues after gallery.)

Girls star Lena Dunham says exercise is vital to her mental health.

The basis for the workout is inspired by the “ toughness ” that Icelanders have developed after “surviving centuries of isolation, cold, enormous volcanic eruptions,” Sogbertsdottir writes on her website.

Not only is it designed to strip fat, increase performance, agility, power, create a long, lean athletic physique and bring the “quickest and greatest” results, Sogbertsdottir claims it will become “addictive”

“I want people to look good but also enjoy exercise more and think about what they’re doing,” she told Look Magazine.

“It is a tried, tested and rock solid method. It will not be hard work. It will not be work. It will be a pleasure. You will love every second of the method and you will love the huge results it will give you.”

If you love the TV show Vikings, this could be the workout for you.

Making intense exercise a pleasure? That would certainly be a miraculous result, abs or no abs.

According to former Ironman and fitness expert Guy Leech (who's trained the likes of Madonna and George Clooney, just FYI!) the Viking method has been proven to achieve fast results.

"It focuses on functional fitness and high intensity training (HIIT) which is great to really burn fat and increase the metabolism," he says.

"It has a heavy focus on strength which is excellent too, particularly in building a tight, toned body and achieving results that you can really see." (Post continues after video.)

Unfortunately it's probably not for the fainthearted, or for anyone who has been a little *ahem* slack with their fitness (*cough* ME *cough*).

"The viking method would be best suited to reasonably fit to very fit people looking to maximise their results and take their training to the next level," Leech admits.

"This method can be a little intimidating for those new to training and those who have a poor fitness base. Because of the vigorous movements, it's also no good for someone who is nursing an injury," he says.

While it's not an exercise you can pick up immediately at home, with initial help it can certainly be a method incorporated into your general workout.
