Having begun their pre-season at the weekend, the Pacers will play the Chicago Bulls on Saturday.
The point guard told the team's website: "I think the energy level that we had today, the amount of communication that we had. Everyone [is] just putting their life on the line.
"Everyone feels like they're 18-year vets in the NBA, body-wise. I think everyone's super tired, over-exhausted and bodies feeling like its breaking down. That's the nature of training camp. You got to take care of your body so that's why we pay our trainers good money to keep us in tip-top shape.
"[I'm] just trying to work hard and be the best player I can be to help this organisation win. Our goal is to win a championship and it starts from me on down."
Hill averaged 14.2 points per game last season.
