Travis Kelce conceded last season took a toll on him, but the Kansas City Chiefs star is confident he can prepare fully for the upcoming campaign.
Tight end Kelce helped the Chiefs to their second straight Super Bowl triumph earlier this year.
The 34-year-old has spent much of the offseason on tour with his girlfriend Taylor Swift, even appearing in some of the pop superstar's shows in Europe.
However, now back at training camp, Kelce is not planning on slowing down any time soon.
"Last year was pretty taxing on my body," Kelce said after Saturday's session at Missouri Western State University.
"I've had more snaps than a lot of guys if not everybody in the NFL over the past five, six years, and I'm very prideful of that, but I know it has taken a toll on my body.
"So it's just making sure that my body's getting that rest and that ability to train harder and be able to withstand an entire 17-to-20-game season.
"This is my sanctuary. Everybody may say that is pretty gruelling, but I enjoy it. There's something about this place to get you ready every single year, and I'm not going to lie, I got pretty excited as the time started counting down to get out here and get this thing rolling.
"This is where it all starts. You can say it starts in the offseason, and yeah, you want to get that foundation set in the offseason of the leadership and the mentality and things like that.
"But at the end of the day, this is where you really find out what the team is made of, how you sharpen the iron, how your guys practice your practice habits, the attention to detail, and nobody does it better than coach [Andy] Reid."
