Cheremisinov took up fencing when he was seven, because there was a fencing hall close to home. His first coach was Lev Koreshkov.^[2]

Cheremisinov joined the Russia national team in 2007. He attempted to qualify for the 2008 Summer Olympics, but his defeat in the quarter-finals of the Lisbon qualifying tournament to Romania's Virgil Sălișcan ended his hopes.^[3]

At the 2012 Summer Olympics he was defeated by Italy's Andrea Baldini in the quarter-finals of the individual event.^[4] In the team event Russia fenced Germany in the first round. Cheremisinov entered the last relay with a three-hit advantage, but he could not hold the lead against Peter Joppich and Russia were defeated 40–44.^[5]

He won gold in the team event in the 2016 Summer Olympics in Rio de Janeiro, Brazil.
