Ektov began his career as a junior and won the national junior indoor triple jump title in 2004. The following year he was the runner-up at the senior indoor and outdoor championships behind Roman Valiyev. The 2005 season saw him improve his best jump to 16.31 m and he also made his first major international appearance, coming seventh at the 2005 Asian Athletics Championships. He became the Kazakhstani national champion both indoor and outdoors in 2006, but he was behind his rival Valiyev on the regional stage – at the 2006 Asian Indoor Athletics Championships Valiyev took gold while Ektov managed the bronze medal. In the 2007 indoor season he set a personal best with a jump of 16.34 m, which brought him the bronze at the 2007 Asian Indoor Games. Although he repeated as the national outdoor champion, he failed to record a mark at the Summer Universiade in Bangkok later that year. Ektov failed to make the podium at the 2008 Asian Indoor Athletics Championships, but achieved a significant improvement in his best on the 2008 Asian Grand Prix tour. At the meet in Korat, he won with a mark of 17.07 m, surpassing the 17-metre barrier for the first time. This made him Asia's third best triple jumper that year, but because it was just short of the Olympic "A" standard Kazakhstan could only send one athlete to the 2008 Beijing Olympics and the more experienced Valiyev got the berth. The 2009 season marked a career progression: Ektov won the national title with a jump of 17 metres exactly and came sixth in a high quality international field at the 2009 Summer Universiade. He represented his country on the global stage for the first time at the 2009 World Championships in Athletics, although he did not progress beyond the qualifying rounds. While fellow countryman Valiyev won at both the 2009 Asian Indoor Games and the 2009 Asian Athletics Championships, Ektov also reached the podium at both events by taking the silver medal indoors and a bronze outdoors. He won a further national title outdoors in 2010 with a wind-assisted 16.96 m and achieved his best legal jump of the season at his most important competition of the year – his clearance of 16.86 m brought him the silver at the 2010 Asian Games behind the home favourite Li Yanxi. The year after, Ektov claimed his first major triple jump title – beating both Li and Valiyev, he produced the third best jump of his career to win the gold medal at the 2011 Asian Athletics Championships.
