The 25-year-old struggled with a foot injury for much of this campaign and was able to make only 15 Premier League appearances for the Hammers, scoring two goals and providing four assists in the process.
The former Liverpool forward also missed out on England's 23-man World Cup squad, but is on manager Roy Hodgson's standby list.
Carroll has now said that he is relishing the prospect of starting the 2014/15 campaign fresh and without injuries.
"I can't wait for the new season to start," he told West Ham's official website.
"I didn't want the last one to end to be honest, I still felt fresh and ready to play more games as I had missed the opening half of the season.
"We had a talk after the last match about the positives and the tough times we had when we were sucked into the relegation fight for a bit, but the gaffer, staff and all the lads had the belief that, once we came through those times and got players back, we could get better and we did.
"Now the focus is to push on and look forward to the new season."
