Kamenov started calisthenics after being inspired through athletes on YouTube. His biggest influencer back in the days was Hannibal for King. He wanted to do a similar thing since he was already motivated since gymnastics intrigued him. Another big motivational factor was his uncle, who is 52 years old and never complains about working out.
Erik Barsi started his calisthenics career in 2017 which is at the time of writing 4 years ago. He mentioned that it has a lot to do with how you train and mainly genetics. Erik Barsi would consider himself as someone who wants to break his own limits.
