Ablyazin competed for the national team at the 2012 Summer Olympics in the men's artistic team all-around. He was the only Russian male artistic gymnast to win two medals, a bronze on floor and a silver on vault behind Yang Hak-Seon of South Korea, at the 2012 Summer Olympics.[5] On the floor, his score tied him for the second-highest score of the night with Kohei Uchimura of Japan and only Zou Kai of China had surpassed him. However, after applying tie breaking rules in gymnastics for the Olympics, Uchimura ended up with the silver and relegated Ablyazin to the bronze. With a D-score of 7.1 on floor, he also executed the most difficult routine during the event final with an extra pass and barely finished his routine in time, right at the sound of the final warning bell indicating his time was over.

In October, Ablyazin competed at the 2014 World Championships in Nanning, China and helped the Russian team to a fifth-place finish. In the apparatus finals, Ablyazin had qualified for three events. Ablyazin even surprised himself to finish ahead of defending champion Kenzō Shirai of Japan and win his first gold medal on floor, scoring 15.750, with just 0.017 difference in their scores, after Shirai stepped out-of-bounds in his third pass and incurred a 0.1 point penalty. Ablyazin's routine in that floor final had the second-highest difficulty score of 7.1 behind Shirai's 7.4, and they were the only two finalist who had difficult values scoring above 7.0. Ablyazin took home the bronze medal on rings too with a score of 15.700. Although he did also qualify for the vault final, he fell on both vaults and finished eighth.
