The No-Nag Method: A Screen-Time Agreement Your Swimmer Actually Signs

I am David Karasek, an Olympic finalist and Swiss record holder in the 200m IM, and I coach the mental side of racing for hundreds of competitive swimmers. A few weeks ago a swimmer texted me: "I want to swim, but I don't feel very motivated." So we opened his screen time. What we found there explained more about his flat training than anything happening in the pool. That conversation became the No-Nag Method, and I ran the first full round of it live inside our free Swimpros community on Skool.

Why nagging stops working around age 12

The instinct to make a new rule is understandable. It's also the thing most likely to backfire. A 2025 study in Pediatric Research followed over 10,000 adolescents aged 12-13 and found that when parents used screens to control behavior, it was associated with higher screen time and more problematic video game use. Calm parental monitoring, without the control, was linked to lower screen time instead. The rule itself isn't the problem. Who it comes from is.

This tracks with a separate 2025 study of 9,519 adolescents tracked from age 9-10 to 12-13: screen time rose by more than 3 hours a day across three years, while sleep duration quietly fell across the same period. For a swimmer whose whole training block depends on recovery, that's not a parenting footnote. That's a performance variable.

Here's the part most parents miss: a rule imposed from outside a 13-year-old triggers resistance almost by design. An agreement they helped write doesn't. That single distinction is the entire method.

What the No-Nag Method actually is

It's not a stricter rule. It's a different process, built on five steps:

1. Identify the need. Screen time is never really about the screen. It's meeting a need — distraction, stress relief, connection, boredom relief, belonging. Ask your swimmer directly: what does this actually give you? You can't replace what you haven't named.

2. Change the environment, not the kid. Once you know the need, find something else that meets it. Bored and want connection? A trampoline park with friends does the same job a scrolling session does, minus the 500 hours a year it quietly costs.

3. Sign the agreement together. Not a rule you impose — a one-page contract you co-write. Ours is called the No-Nag Agreement, and the difference is simple: a swimmer defends a plan they helped build. They resent one that was handed to them.

4. Track it like a training log. Screen time, sleep, and morning energy, logged daily. A 2019 self-monitoring study in youth behavior change found tracking combined with goal-setting outperformed almost every other intervention type — the same reason a training log works better than a coach's memory. Once a swimmer sees last week's number, beating it becomes the game.

5. Let the results shift the identity. This is the part that makes it stick without a single reminder from you: better sleep shows up as better times in the pool. Once a swimmer starts thinking of themselves as someone who protects their recovery, they defend the habit on their own. That's internal motivation, and it's the only kind that survives you leaving the room.

The 3-question baseline check you can run tonight

This is the exact opener we used to launch the first round of the No-Nag Method — no app, no lecture, five minutes at the kitchen table.

Two easy wins to add immediately, straight from the agreement: no phones at the dinner table, parents go first, and phones away 30 minutes before bed. That's the entire parent job in this method. Everything else belongs to the swimmer.

What Swimpros families are actually saying

When we opened the baseline check inside the community, the honesty is what stood out. From swimmers:

I think I am just doing it to not have to do the stuff I really have to do... if I check social media I feel like I then know the new trends and what happened, and I don't want to feel left out. - Liv, 13, Swimpros community

And from parents, watching from the other side:

She's consuming so much mindless content that there's little room left for boredom, creativity, or simply being present in real life. - Nadja, Swimpros parent

When he is not on his phone so much, he is more relaxed and we end up having nicer conversations, which I really enjoy. - Galabina, Swimpros parent

Even I signed my own version. Small honest detail: I'm having my wife co-sign our son's agreement instead of grandparents. As I told the group, she has more leverage than my parents these days — use whoever actually has it in your house.
