Corina Constantin

In January 2017, Constantin announced her second retirement, having accomplished all she wanted to in the sport. "At my last world championships, I won silver", Constantin said, "and [in Korea], I took my revenge."

Since retiring from Gymnastics, Constantin continues to be an active member of the Romanian gymnastics community, coaching aerobic and artistic gymnastics, and continues to be a member of the AEROS troupe. At the 2017 European Artistic Gymnastics Championships in Cluj-Napoca, Romania, Constantin performed in the opening ceremonies.

In 2016, Constantin was a member of the Romanian Gymnastics and Modern Dance troupe, AEROS which toured in Italy and Switzerland from February to March.

After a year long break, Constantin announced she was coming out of retirement with hopes to win the gold medal in Individual at the 2016 World Championships. "It is the only thing missing." Constantin said.

This title further fuelled Constantin's goal to win the 2016 World Championships.

Constantin's 2016 season started off with the Cantanhede World Cup in Portugal where she won the gold medal in individual women with a 21.900, placing ahead of teammate Bianca Gorgovan and Hungary's Dora Hegyi who scored 21.425 and 21.150 respectively.

At the 2016 World Championships Constantin walked in hungry. In trio qualifications, Constantin, Surdu and Bogati, who also came out of retirement, placed 11th with the score of 20.113, missing out on the finals. Eager to win the individual gold medal, Constantin qualified into the individual women final in second place behind China's Yu Yangyang. Scoring a 21.800 in qualifications, Constantin won the gold medal with a massive score of 22.050, 0.3 ahead of Yu Yangyang.

She states her most memorable achievement as winning the 2015 European Championships and her greatest ambition being to win gold at the 2016 World Championships.

The 2015 European championships, held in Elvas, Portugal were Constantin's first competition since her retirement. In qualifications, Constantin scored a 21.350 placing her into the final .100 ahead of leader, Dora Hegyi of Hungary. In the finals she won the individual women's title ahead of Hegyi, who scored a 21.650, with a 21.750.

Constantin competed well in 2014 winning the gold medal in individual with a 21.400 ahead of teammate Bianca Maria Becze, and the silver medal in trio with teammates Surdu and Bogati at the 2014 Suzuki World Cup. At the 2014 Barovets World Cup, in Bulgaria, Constantin won gold in both Individual and trio competitions scoring a 21.350 and 20.700 respectively in each routine. In Portugal at the 2014 Ponta Delgado World Cup, the Romanian Trio once again won gold with a 21.205. In individual competition Constantin's winning streak was ended by Austria's Lubov Gazov. Constantin won the silver medal with a 21.600 after qualifying in third position with a mere 20.950.

In Cancun at the 2014 World Championships Constantin was once again a favourite to win the gold medal along with Austria's Lubov Gazov and France's Aurelie Joly. She qualified into the final in third place with a 20.850 and won the silver medal, behind Gazov with a 22.000. After being victorious at their last two international competitions, the Romanian trio of Constantin, Bogati and Surdu was victorious and won the gold medal with a 21.541 after qualifying into the final in a disappointing third place. The Romanians continued to build on their success and the group of Constantin, Bogati, Surdu, Becze and new senior Bianca Gorgovan won the gold medal in the group finals ahead of France with a 21.705.

After retiring in 2014, Constanin worked as an pilates instructor and as a gymnastics coach.

The 2013 World Games was where Constantin's talent was on full display, qualifying second into the Individual final with a 21.050, Constantin beat out first qualifier Aurelie Joly of France to win the gold medal with a 21.450.

At the 2012 World Championships, Constantin was a favourite to win the gold medal along with Spain's Sara Moreno. Unfortunately, Constanting scored a 21.100 in the qualifications, which was enough to qualify her into the finals in third place. In the finals Constantin finished a disappointing fourth place with the score of 21.150.

Constantin's first major International event was at the 2011 Aerobic Gymnastics European Championships where she won the gold medal in Individual Women with a 21.500. Here, Romania also placed second in the group with a score of 20.794 by Constantin, Maria Luisa Pavel, Laura Cristache, Delia Lacataru, Anca Surdu, Andreea Bogati, all members of the AEROS troupe. This event led to Constantin being selected as a member of the Romanian team who would be competing at the 2012 World Championships.
