How to Stay Fit When You Have Young Kids: The Honest Guide

Nobody tells you before you have kids that your fitness will essentially be put on hold for a few years. The sleep deprivation, the mental load, the complete evaporation of free time — it’s a lot. But staying reasonably fit during these years isn’t impossible. It just requires a different approach.

Lower the Bar (Temporarily)

This is the first and most important mindset shift. You are not going to train the way you did before kids for a while. Accepting that means you can focus on what’s actually achievable rather than feeling guilty about what you’re missing.

The goal with young kids isn’t peak performance. It’s maintenance — keeping enough muscle, keeping enough cardiovascular fitness, and staying sane. That’s a completely legitimate goal and it’s achievable even in the most chaotic parenting phases.

The Minimum Effective Dose

Research suggests you can maintain most of your fitness with as little as two 20-minute sessions per week of resistance training. Two sessions. That’s it for maintenance. Finding two 20-minute windows in a week is hard with young kids, but it’s not impossible.

When to Train With Young Kids

Before They Wake Up

The most reliable window. If your kids wake at 7am, a 6am alarm gives you 45–60 minutes of uninterrupted time. This requires going to bed earlier — which is worth it. Many dads find this the only truly reliable training window.

During Nap Time

For dads with babies and toddlers still napping — this is gold. The temptation is to collapse on the sofa, and sometimes that’s the right call. But even three nap-time sessions a week of 20 minutes changes your fitness trajectory significantly.

After They’re in Bed

Works well but requires energy you often don’t have. The advantage: no time pressure. The disadvantage: training at 9pm can disrupt sleep. If this is your window, keep intensity moderate and finish at least 90 minutes before you want to sleep.

During Their Activities

Football training, swimming lessons, dance class — while they’re doing their thing, you could be doing yours. A pair of wireless headphones and a bodyweight workout plan on your phone is all you need to turn 45 minutes of spectating into training time.

Training With Your Kids

Some of this is genuinely useful, some is wishful thinking. What actually works:

• Running with a buggy — harder than regular running, good workout, kids often enjoy the motion
• Cycling together — a bike seat or trailer extends your cycling range while kids are small
• Park workouts — pull-ups on playground equipment, step-ups on benches, lunges around the park. Looks ridiculous, works well
• Playing actively — chasing, wrestling, swimming with them. Doesn’t replace structured training but contributes to overall activity

What doesn’t really work: trying to do a focused strength session while supervising a toddler. Save that for when they’re contained or occupied.

The Home Gym Advantage

A gym membership is nearly useless with young kids — you can’t just leave the house for an hour whenever you want. Home training removes the travel, the changing room, the drive. When you have 25 minutes, you train for 25 minutes rather than spending 20 of them getting there and back.

A kettlebell, a pull-up bar, and a mat is all you need. See our guide to home gym equipment for dads for specific recommendations at every budget.

Nutrition: The Lower Effort Wins

With young kids, elaborate meal prep and strict dieting is unrealistic. Focus on the basics that require minimal effort:

• Protein at every meal — eggs, Greek yoghurt, chicken, tuna. Simple, fast, high protein
• A protein shake on busy days — 2 minutes, 21g protein, done
• Don’t eat the kids’ leftovers — fish fingers and chips off their plates add up
• Reduce, don’t eliminate — cutting alcohol from 5 nights to 2 nights is more achievable and more impactful than going teetotal and lasting a week

Give Yourself Some Grace

Some weeks you’ll train three times. Some weeks the kids will be ill, you’ll be ill, work will be chaos, and you’ll do nothing. That’s parenthood. The measure of fitness with young kids isn’t any single week — it’s the pattern over months.

Two sessions a week, most weeks, is enough to maintain and slowly improve. It’s not Instagram fitness. It’s real life fitness. And it’s absolutely worth doing.
