THE NAP WINDOW WORKOUT
If you're reading this, you're probably someone who used to love training. Someone who before being a mum, had a routine, felt strong, felt like yourself. Then had a baby and watched all of that pretty much disappear.
You are not lazy. You are motivated. You are disciplined. But you are exhausted. And exhaustion makes everything feel impossible, especially exercise.
But, you don't need a two-hour gym window. You just need to know when your baby is likely to nap and have a workout ready to go the moment they close their eyes.
That's exactly what this guide is. A simple, realistic workout plan mapped to your baby's nap windows by age. No guesswork. No wasted time standing in the kitchen wondering if you should eat, sleep or exercise.
Let's get you moving again.
How to Use This Guide
Find your baby's age range, check the typical nap pattern for that stage, and choose the workout that fits your available window.
A few things to keep in mind:
Every baby is different. These are general nap patterns, not guarantees.
Start the workout the moment baby goes down. Don't wait to see if they'll actually sleep.
Done is better than perfect. A 15-minute workout you completed beats a 45-minute one you didn't start.
If naps are unpredictable, that's a sign worth looking at. More on that at the end of this guide.
Please get clearance from your GP or a women's health physiotherapist before beginning any exercise programme postpartum.
0 – 5 Months: The Fourth Trimester Plus
What's happening with sleep
Newborns sleep a lot but rarely in predictable chunks. Naps can range from 20 minutes to 2 hours and happen up to 5 times a day. This stage is survival mode, and that's completely normal.
Around 4 months, babies often face a regression in sleep as they start to sleep in cycles but these are still unpredictable.
Your nap window: 20–45 minutes
This isn't the time to push hard. Your body is still recovering from birth, your hormones are all over the place, and sleep deprivation is real. Gentle movement is your goal here and it still counts.
The 20-Minute Recovery Reset
Do each exercise for 40 seconds, rest for 20 seconds. Focus on breathing and building back up your core. Repeat the circuit twice.
5 - 8 Months: Finding a Rhythm
What's happening with sleep
Naps start to consolidate. Many babies this age take 3 naps although wake windows should still be followed. A longer morning nap (1.5 – 2 hours), an afternoon nap, and a short late-afternoon power nap.
Your nap window: 60 - 90 minutes
You're starting to see more predictability as baby starts to settle into a routine, which means you can plan ahead. This is the stage where getting back to intentional movement becomes more realistic. You have enough time for a proper session if you move quickly when baby goes down.
The 30-Minute Strength Reset
3 rounds of the following. Rest 30–45 seconds between exercises.
8 - 15 Months: Two Nap Territory
What's happening with sleep
Most babies move to 2 naps around 8 months. A morning nap and an afternoon nap. Each can last around 1.5 hours each.
Your nap window: 60 – 75 minutes
You now have two fairly long windows per day to work with. Why not work out for one and rest for the other. The key is to start you work out immediately and not spend 10 minutes scrolling before you begin.
The 45-Minute Full Body Blast
4 rounds of the following. Rest 45 seconds between exercises.
15+ Months: The Long Afternoon Nap
What's happening with sleep
Around 15 months babies are often starting to transition to 1 nap however, it is possible for some to still be on 2. When down to one nap, it is typically in the middle of the day around 12/1pm for around 2 hours. This is a brilliant training window.
Your nap window: around 90 minutes
This is your biggest opportunity. A 90-minute nap window gives you time for a proper workout AND a few minutes to cool down and eat something before baby wakes. Use it.
The 60-Minute Strength & Cardio Session
Split into two blocks. Do each block twice before moving to the next.
BLOCK A — Strength (x2)
BLOCK B — Cardio (x2)
Remember – make the most of your baby’s naps. A 15-minute workout is better than a 45-minute workout that didn’t happen.
Ready for a Sleep Plan That Works Around YOUR Goals?
This guide gives you the workouts. But if your baby's naps are unpredictable, short, or fighting you every time no workout plan will fix that.
That's where I can help.
I'm a sleep coach who works specifically with mums who want to get back to training. When we work together, I don't just look at your baby's sleep I ask about your fitness goals, when you want to train, and what you need to make movement happen. Then I build a sleep plan around all of it.
You've got this. One nap at a time.
