He was also the sixth man to lift at least triple his bodyweight in the clean & jerk in international competition, having done so seven times;[6] the others are Naim Süleymanoğlu, Stefan Topurov,[7] Long Qingquan, Halil Mutlu, and Neno Terziyski.

Om was picked up by the weightlifting instructor Sin Gap-jun while practicing football at the local sports school.

[9] At the men's 56 kg weightlifting event at the 2016 Summer Olympics in Rio de Janeiro, Om was a favorite to renew his gold from London.

After breaking his own Olympic record with a lift of 169 kg, Om was surpassed by Long Qingquan and had to settle for the silver medal.

His total was tied with second place Thạch Kim Tuấn but he won by virtue of a lighter body weight (55.71 vs. 55.75).
