The defender, who has one cap for England is currently being put through his paces alongside the rest of the squad in North America as the Reds continue their pre-season preparations for the start of the new season, in the heat of Boston.
He is set to be involved as Brendan Rodgers' charges face AS Roma at Fenway Park on Wednesday night, and he is hoping to repay the faith the manager has shown in him.
Liverpool's No.34 has described the upcoming season as 'massive' for him, and admits he now feels 100 per cent confident and strong as he looks towards reaching a peak level of fitness through playing competitive matches.
"I think in terms of confidence and feeling strong I'm definitely 100 per cent, but in longer terms that takes games," Kelly told Liverpoolfc.com.
"You can't replicate that in training, so the more games I play, the more I'll get up to that peak fitness which is what I need this season - it's a massive season for me.
"I've been fit for a season now but I haven't had the games, so the run of games is vital for me this season and hopefully they'll come in this pre-season.
"As a young lad you train and then you play at the weekend, so to train throughout the week and then not play at the weekend was difficult [last season].
"But I'm still part of the team, I was still travelling to all the games and I still felt a part of it. That's what was good from Brendan - to keep me involved with the team.
"I'm just looking forward to this season, enjoying my football, enjoying being here with the team and it's exciting times for Liverpool as you know."
With games coming up against AS Roma, Olympiacos and Manchester City in quick succession - which you can watch live on LFCTV GO, Kelly will have plenty of opportunities to boost his match fitness ahead of an exciting season.
