Despite representing Great Britain at the Beijing Olympics in 2008, Keatings failed to make the team at London 2012 with injuries hampering his chances.
This meant the 23-year-old was forced to watch on as the British men's team won an historic bronze medal in the capital last summer, the first time this had happened since 1912.
However five gold medals at last month's British Championships proves that Keatings is getting back to his best, something he is eager to prove to his continental rivals in Russia.
"It was important not to dwell on the disappointment of London 2012," said Keatings, who won pommel horse gold at the 2010 European Championships in Birmingham.
"The best way to go about it is to use that as fuel for your fire and that's what I've done.
"I've got my head down in the gym and worked hard because I wanted to prove a point and get myself back on the team. Now I can hopefully start achieving some great things again.
"I'm definitely happy. The last two years have been hard through injuries and not making the Olympic team, so I wanted to come back with a bang.
"I'm in a different place now. This time last year I was coming back from some serious ankle injuries, I felt a lot of pressure, mentally and physically, it was challenging. I've cleared my mind completely now, I'm feeling in great shape and confident."
