Recently, Kristaps Porzingis' days have started around 6:45 a.m.

He’s up at that hour to prep for his first NBA training camp with the New York Knicks.

After breakfast -- his first of several meals throughout the day -- Porzingis heads to the Knicks' training facility to start working out.

On some days, he begins by working on his shot. Weightlifting starts at 8 a.m.

At 9 a.m., he’s on the court with his teammates, stretching and going through some of the Triangle offense.

Next he’ll participate in 5-on-5 scrimmages for a couple of hours with the other Knicks. After the games, which Porzingis says can get competitive, the rookie has his second meal of the day.

Then he heads home for a nap and another meal (getting closer to his 5,000 calorie-per-day mandate).

Porzingis says he’s back in the gym by 6 p.m. for another hour of weight training.

And then?

“Get some ice if I need it, go home and get some rest.”

Rinse, repeat.

This is the process Porzingis has followed in recent days to add some muscle to his 7-foot-1 frame.

Last week, Porzingis said he’s put on 11 pounds. He hopes to add four more before the start of training camp Tuesday.

“I was real skinny in the summer league, so now I’m putting on some nicer weight that’s probably 90 percent muscle that helps me,” he told MSG Network. “I even feel stronger, quicker and I can jump a little higher. I don’t think [the weight gain] will slow me down. I think that will make me quicker and maybe even more athletic.”

Porzingis’ weight -- along with his overall development -- is one of the more intriguing aspects of the preseason for the Knicks. It’s not a stretch to say that the Latvian is the most important Knick outside of Carmelo Anthony.

The Knicks’ short-term future -- and, to some extent, the legacy of team president Phil Jackson -- will be dictated in part by whether Porzingis is successful in the NBA.

If the No. 4 overall pick develops into the player the Knicks envision, New York will have a star to build the roster around after Carmelo Anthony. But if Porzingis falls short of expectations, the Knicks will have squandered their best draft pick in 30 years.

Those are issues for another day, though.

For now, Porzingis is focused on getting to Tuesday morning.

“Can’t wait for training camp to start and to fight for my spot,” he said.
