28-year-old Eirik Lundstein from Elverum, Norway, is doing jumps and flips with kettlebells in his arms. He has recently posted a video of him doing so and has received more than 50,000 views on YouTube and over 2 million on Facebook.
This guy’s workout technique is really special as it is very dynamic and requires a lot of gymnast skills as backflips is a big part of it. Lundstein has started training in 2009 and after the video went viral he woke up famous.
His passion grew from a desire to challenge himself and also an interest to play with gravity as weights change the center of gravity and momentum. “I would not recommend this to anyone unless they really know what they are doing,” he says. “There is a lot of body control, body strength, and understanding of momentum needed to be able to do this and not get injured,” Lundstein told in the interview.
