I also hadn’t done core work before. I started doing a lot of heavy lifting and cardio. At Villanova, we didn’t really do conditioning; our cardio was open gym, which made me lose a lot of weight really fast.

You said you were lifting heavy weights—how’d you stack up to your teammates? You played with some pretty talented guys.

Oh, I was lifting the heaviest. Once I started gaining muscle, I would lift the most by far. It wasn’t really a competition, but people definitely tried to lift the same weights as me.

So you were by far the strongest player at Villanova. What about in the Warriors weight room?

I don’t lift the same way I did at Villanova, so I actually don’t know yet.

Probably a smart, diplomatic response given that you play with a bunch of all-stars you don’t want to piss off.

[Laughs] No, I honestly don’t know! We haven’t done any really heavy weights. One day it’ll happen.

What did you work on over the summer leading up to this season?

During pre-draft prep, I was working out with my agency, CAA, and Don MacLean, a former NBA player who was helping me. He made sure I was in good shape. I signed up for something called Sunfare, which is a meal delivery service, to assist with my diet.

Nowadays, I don’t do the meal delivery service, because the Warriors cook for us. I just eat whatever the chef makes. We always have a brunch before we get on the plane to travel, so for that, I try to have a bacon, egg, and cheese, or turkey bacon, or maybe some chicken meatballs. If it’s a game day, I’ll eat some light carbs, but otherwise, I’ll stay away from them, because I don’t digest them as well. I’m pretty disciplined about that stuff. After practice, they’ll usually make us something like salmon with broccoli and squash. If you want carbs they have sweet potatoes—lighter stuff.

Honestly though, I was a picky eater growing up. When I was younger, I loved french fries. As I got older, I started to expand my palate a lot more, and I’ve gotten better at avoiding certain foods. There are healthy alternatives to everything now, so I’m always looking for those.

How have you adjusted to the NBA grind? Do you feel like you’ve settled into a routine yet?

No, I wouldn’t say I’ve totally settled in. It’s something I’m still dealing with, especially the back-to-back games and all of that. But I feel like I’m adjusting well; as long as you hydrate properly, that helps a lot. I used to be a Gatorade guy, but now I drink a lot of water—especially sparkling water. I’m really big on sparkling water. I have a lot of that in my house. I don’t know why some people don’t like it, I think it’s great.

Also, I tend to recover really fast, so more recently, I started lifting before games. And the day after a game, instead of just sitting around, I want to get some sort of workout in to sweat and get my blood flowing. There are a lot of little things that I’ve learned about my body over the years.

I know you came into the league as a strong dude, but I have to imagine it’s still jarring figuring out whether you’re capable of physically matching up against other NBA players. Was there a moment in a game when you realized, Oh, I can do this?

I actually came in on day one feeling like I could hold my own. But there was a moment guarding LeBron, he was bumping me a little bit and I didn’t fall back as much as I thought I would. To be clear, there were also a few times when I thought, Alright, LeBron is pretty strong. Steven Adams is really strong too. But I do feel like I belong.
