NEW: Russian bodybuilder and daredevil Sergey Boytsov claims to have set a world record.
Boytsov claims to have set a world record for the world’s first gymnastic turns under a balloon at an altitude of 1500 meters *without* a parachute.
Boytsov says there was no “insurance,” meaning if something went wrong, he was done.
Boytsov is 30 years old and is from Russia.
