Ryan Reynolds on the Struggles of Becoming a Father: 'It's Amazing That You Find a Way to Keep Going'

Men's Health

Ryan Reynolds gets real on becoming a dad, and having to say goodbye to his own father, who died last October.

Ryan Reynolds is getting candid about the responsibilities that come with being a father.

The 39-year-old actor and his wife, Blake Lively, welcomed their daughter James in December 2014. But he admits it hasn't all been smooth sailing when it comes to being a first-time dad.

"During those first six months, it's amazing that you find a way to keep going," Reynolds tells Men's Health, covering their March issue. "Just the lack of sleep, and the hallucinations. F**k peyote. You want to trip balls? Have a kid and see what it's like to be awake for a month straight."

"You'll have moments where you're like, 'Did I really ride a unicorn to work? I'm pretty sure I didn’t, but I don't know,'" he jokes. "Was Willie Nelson cradling my testicles this morning? It probably wasn't him, but let me check his tour schedule just to be sure.'"

The Deadpool star admits he's still overly cautious when it comes to his baby girl.

"I still check on her in the middle of the night and put my fingers under her nose just to make sure she's still breathing," he admits. "Is that insane? I feel like it might be a little bit insane."

But joking aside, Reynolds also opens up about the final moments he spent with his father, James Reynolds. The father of four sons died last October after a long battle with Parkinson's disease.

"I got to say goodbye to him. I got here [Vancouver] while he was still conscious, and had some pretty valuable time with him," Reynolds recalls. "In my dad's dying moments, we were making him laugh. We were all in there together, me and my brothers, just joking with him. And of course, we end up busting each other's chops."

"It wasn't a bad way to go," he continues. "If I could have the same death as my father, I would do it right now."

Still, it hasn't been easy dealing with his death.

"We had a deeply complicated relationship, and it leaves behind some questions that are still being answered," Reynolds says. "Not just about him but, you know ... how I'm trying to get better at being a dad and a husband and a man."

But by all appearances, Reynolds is succeeding on all fronts, and fans are now eagerly awaiting his turn as the sarcastic anti-hero Deadpool. Reynolds talks to the magazine about how he stays in superhero shape

"I get depressed if I don't move," Reynolds shares. "So for me, that’s enough. I don't necessarily need to have 400 pounds on my back in the squat rack and then take a picture of myself and send it out to my Twitter followers: 'Part of the 400-pound club today.' I like to hike and go biking, that kind of thing. Get outside, move my body, get some fresh air pumping through my lungs. That's my idea of a workout now."

And he's also getting real about how his fitness routine has changed on account of his turning 40 this year.

"I never did stuff like that back in my 20s," Reynolds admits about warming up. "But I'm that guy now. I'm the guy doing calisthenics. I'm doing jumping jacks and deep knee bends. I work out like a British person."
