The Chelsea defender was ever-present for the Blues least season, helping them win the Premier League.
Terry said he puts in extra work in training and in pre-season to ensure he can prolong his playing career.
And the 34-year-old hopes to follow in the footsteps of Giggs, who retired aged 40 last year to become assistant coach at Manchester United.
The former England skipper told Sky Sports News HQ: “In the last four or five years I’ve done a lot of extra work, not just at the training ground.
“The kids are a bit older now so I get a bit more of a lie-in.
“Putting the effort in the gym, training ground, off the pitch and eat the right food, I’m hoping to carry on as a long as possible.
“There’s an opportunity you see with players like Giggs of playing until a very big age.”
Chelsea, who face Fiorentina in a pre-season friendly on Wednesday, kick off their league campaign against Swansea City on Saturday.
And the defender said Sunday’s defeat to Arsenal in the Community Shield has made the squad more determined to retain their title.
He said: “Sometimes you win, win, win. It’s not nice losing, we wanted to win the Community Shield.
“The only positive was we played well and more importantly the disappointment within the squad can be a wake up call, it could be a blessing in disguise.”
He added: “We are the team to catch.
“We realise we need to go on another level to last year which is going to be a tough task.
