Roy Hibbert has become a vastly improved player since coming into the NBA, at least partially due to his conditioning. 

Hibbert has added MMA training into his offseason routine over the past few years.

"It pushed me to my limit sometimes," said Hibbert. "We used to break things up, where we'd have 30 minutes of mitts, just punching. And then we'd do like a Cross Fit workout, where I may have to run on the treadmill, do some Burpees, do some pushups, do some ropes, do some wall getups, stuff like that. Or, like, get on the ground, and have to get up with somebody on top of you. It's just mentally fatiguing, and it strengthens you a lot more. Last game [Game 2], I'm, at the free-throw line, and I'm obviously tired, and I hear fans in the Miami section saying, 'Hey, Roy, you're bending over, you're looking tired, looking tired.' I'm like, this is nothing compared to what I did during the summer. During Game 6 of the Knicks series, I'm exhausted. I'm bending down in the timeout, 20-second timeout, basically on the ground. I'm exhausted. And the next play out, I get that block. It's just trying to be resilient. We need to get further. So that's what was on my mind."
