The former Leeds United youngster struggled for a starting spot last season, his first at the club since his £7m move from Leeds 12 months ago.
His season was hampered by an ankle injury he picked up in October and he made just six appearances in the Premier League but, after a great summer captaining the England Under-20s to World Cup glory, he is ready to make his mark for the Cherries.
He told the Bournemouth Echo: "Last season was full of ups and downs but I definitely grew as a person and learned how to deal with things. I felt I improved in my training last year and had a few games towards the end of the season. I thought I did well.
"Going away in the summer and doing what we did there put me in great stead. There is a lot of competition for places here. Hopefully, the team can do well this season and we can have a really good go."
