Pavel Tsatsouline, Master of Sports, is a former Soviet Special Forces physical training instructor who has been called "the modern king of kettlebells" for starting the Russian kettlebell revolution in the West.

In 1998 Pavel introduced the ancient Russian strength and conditioning tool to the American public in his subversive article, Vodka, Pickle Juice, Kettlebell Lifting, and Other Russian Pastimes. The article was published by MILO, a magazine for tough hombres who bend steel and lift rocks. When Pavel started getting mail from guys with busted noses, cauliflower ears, scars, or at least Hell's Angels tattoos his publisher took notice.

In 2001 Dragon Door published Pavel's groundbreaking book The Russian Kettlebell Challenge and forged the first US made Russian style cast iron kettlebell. RKC™, the first kettlebell instructor course course on American soil, kicked off.

Several years later Dragon Door published Pavel's book Enter the Kettlebell! which became the golden standard in kettlebell instruction. It was followed by Return of the Kettlebell which introduced the most advanced Russian strength and muscle building techniques.

Pavel is a subject matter expert to the US Marine Corps, the US Secret Service, and the US Navy SEALs. A kettlebell in his fist, he was voted the 'Hot Trainer' by Rolling Stone and appeared in media ranging from Pravda to Fox News. Dr. Randall Strossen, one of the most respected names in the strength world, stated, "In our eyes, Pavel Tsatsouline will always reign as the modern king of kettlebells since it was he who popularized them to the point where you could almost found a country filled with his converts…"
