The England Under-21 captain, who moved to Merseyside from Sunderland in 2011, believes that putting in the extra work will eventually ensure a regular starting spot under manager Brendan Rodgers.
"A lot of players do extra training," Henderson told the club's official magazine. "I tend to work on my finishing. I think it's important as a midfielder to contribute goals.
"The goalkeepers stay behind with Mike Marsh along with a few of us. I think I need to improve in a lot of areas. Scoring goals is one of them.
"It's such an important part of football. If a manager knows he can rely on a midfielder to score a few, it means he's likely to play a lot."
Henderson has featured 37 times for the Reds so far this season, scoring four goals.
