Fatherhood has a way of stripping away the illusion of control. Peter Nelson II learned that quickly.

Peter lives in Cleveland, Ohio with his wife and their three kids, ages four, two, and a newborn just weeks old. He’s the founder of SISU, a wellness brand rooted in heat, resilience, and ritual, and Hell on Hogsback, an endurance race that pushes people toward their physical and mental edge.

Those same themes show up at home.

Letting Go of Control

The hardest part of parenting for Peter hasn’t been the lack of sleep or the packed schedule.

It’s accepting that no matter how much you plan or prepare, you’re not fully in control.

Instead of fighting that reality, Peter and his wife choose to focus on balance and inclusion. Their kids see their faith practices. They see focused family time. They see the work of building a business. They see the discomfort that comes with training for races and adventures.

Nothing is hidden. Life is lived out loud.

Why the Small Moments Matter

The most rewarding part of fatherhood has been watching how inquisitive his kids are and how much they remember. The smallest actions stick. A tone of voice. A habit. A response in a stressful moment.

Those observations force Peter to double down on what he and his wife feel called to do each day. It’s deeply rewarding and a little bittersweet. A reminder that time is passing whether you’re ready or not.

Learning Fatherhood in the Trenches

One thing Peter wishes he knew earlier is that there’s no manual for being a great dad. You learn it in real time. In the trenches.

That means trusting your gut. Knowing when to lead and when to support. Understanding your role as a husband as much as a father. And remembering that while the days feel long, the years move fast.

The advice that’s guided him most is built around what he calls the three P’s. A dad is called to be a Provider, a Protector, and a Priest. Providing fulfillment for each family member. Protecting a home that feels safe and open. And keeping faith at the center so everyone can lean into God’s calling for their lives.

A Day Built on Intention

Life looks different with a newborn in the house, but when they’re outside that window, Peter and his wife start early. Around 4:45am, coffee and workouts come first. He jumps into the SISU sauna, then wakes the kids around 6:30.

Mornings are for pancakes, lunches, hugs, and school drop-offs. Work runs from mid-morning through early afternoon, followed by a daily run. Late afternoons are for pickups and evenings with the family.

A few rhythms anchor the week. Twice-weekly no-phone evenings. Monthly one-on-one dates with each kid. Regular date nights with his wife. None of it is perfect, but the intention is clear.

Keeping Priorities in Order

When work, life, and family all collide, Peter filters everything through a simple hierarchy. Faith first. Family second. Fitness third. Work last.

If something pulls him away from family time, the answer is usually no.

When things feel overwhelming, it’s often a sign that the order slipped. Re-centering on movement, training, and time alone helps him reset. His grounding tools are consistent. Running. Sauna. Physical strain that clears mental noise.

Non-Negotiables That Last

Peter’s non-negotiables are rooted in presence. When his kids are talking, the phone stays down. Eye contact matters. Listening matters. And when they ask him to wrestle, he always says yes. Every time. Because you never know when the last time will come.

When he’s flying solo, Peter leans into travel, long races, lifting heavy, good food, and a cold beer. Simple pleasures that fuel the bigger work.

Peter’s approach to fatherhood mirrors how he lives everywhere else. Lead with intention. Embrace discomfort. Stay present. And don’t miss the moments that matter most.
