Like many parents balancing work and childcare, doctor and mum-of-three Lucy Demaine, 33, can’t always make fitness a top priority. Still, she knows just how important it is for both physical and mental health.
‘Working as a doctor, I’ve seen first-hand the effects of poor lifestyle choices on patients, and the profound impact this has on long-term health,’ she tells WH. It’s completely shifted how she thinks about fitness.
A former elite rugby player – she competed in the 2016 Six Nations – Lucy was once used to intense training. Now, though, her focus is on ‘longevity, resilience and being able to fully participate in life.’
Below, Lucy explains how she approaches fitness today, and the sessions she swears by.

A former elite rugby player, Lucy’s approach to fitness has changed in recent years
How to take the pressure off
While she says she’s still finding her feet with fitness two years postpartum with twins, Lucy has found a way of training that works for her. And with three young children and a very busy work schedule, it’s not neat and structured.
‘Coming from a rugby background, I was used to structured training blocks – 12-week strength cycles, fixed sessions and clear fitness progression. But that just doesn’t work for me anymore,’ she says. ‘I don’t know if I will train once in a week or four times. I don’t know how I will feel day to day, as that depends entirely on sleep, work and the kids. So instead, I have shifted to something much more flexible.’
What does that look like? ‘I keep a bank of short workouts I can choose from depending on my energy and time – all around 30 minutes long: upper-body, lower-body, full-body, high-intensity, or running,’ Lucy explains. ‘That means there is no pressure – I just focus on doing some form of movement that fits into my daily life.
The workouts
‘These are the kinds of sessions I rotate depending on how I’m feeling. Nothing complicated – just simple, effective and easy to start. They work because they take 30 minutes or less, require minimal equipment and can be scaled up or down depending on energy,’ says Lucy.

‘For me, that is Tuesday night netball. It is in the diary, and it does not move.’
2. Keep workouts short
‘30 minutes is enough. It doesn’t need to be perfect, just consistent.’
3. Stay flexible
‘Tired or stressed? Swap the intensity, not the habit. Something is always better than nothing.’
4. Have the workouts ready to go
‘Having a bank of sessions you can choose from depending on how you feel takes the thinking out of it.’
5. Ditch the all-or-nothing mindset
‘Missed a session? It does not matter. Start again tomorrow. This is about long-term consistency, not perfection – something I have really had to learn since becoming a mum.’
