How busy women can realistically hit 10 hours of exercise a week – and unlock the biggest health benefits

A huge new study published in the British Journal of Sports Medicine – which analysed the activity levels of more than 17,000 participants – suggests that to achieve a substantial (defined as greater than 30%) reduction in heart attack and stroke risk, adults should aim for 560–610 minutes of moderate-to-vigorous physical activity per week. That’s considerably more than the current 150-minute minimum guidelines for health benefits, so it’s perhaps unsurprising that only 12% of people in the study achieved it.

It’s not to say there wasn’t any reduction in risk for lower totals – just not what scientists class as ‘substantial’. And it’s also important to note that the study was observational, meaning it cannot prove any kind of direct link; just association. It could be the case, for instance, that participants were already healthier and fitter than the general population. Plus, neither sedentary time nor less vigorous exercise were measured.

When WH put the findings to personal trainers, they were very keen to stress that something is always better than nothing – and they also had some useful tips for giving it your best shot at getting those golden 10 hours in.

Olivia Horncastle is a personal trainer helping busy women and mums fit exercise into their schedules.

Habit stack

‘I get my busiest clients to habit stack movement – so every time they fill up a kettle, they might do some squats, when they brush their teeth, they might do a wall sit,’ says Horncastle. ‘Other small things like trying to take calls while walking, or stretching in front of the TV at night work well. It doesn’t need to always be adding a full workout – all small additions help.’

5-minute workouts matter

‘Even starting with a 5-minute bodyweight circuit and building that up over time starts a habit – something is always better than nothing.’

Set yourself daily or weekly challenges

That might be trying to do 50 squats throughout the day, increasing your steps by parking further away at the shops, or taking the stairs instead of the lift, says Horncastle.

Tie exercise into your social plans

‘Instead of drinks with friends, I might suggest we go for a walk and grab a drink at the end, or try a new Pilates class instead of brunch etc.’

Michael Baah is a strength coach and oncology exercise specialist working with busy professionals, athletes and people recovering from cancer. ‘All that protection for your heart works best if you maintain your muscle mass, too,’ he cautions. ‘If you walk a lot but never do any strength work, you actually lose muscle faster, and after age 30, women naturally lose about 1% of their muscle every year unless they use it.’

Baah recommends doing three 45-minute strength sessions a week, using simple, compound moves (think: squats and deadlifts) that work your whole body. ‘You should finish each exercise feeling like you could maybe do just one or two more reps – this is the safe and effective method we use in clinics.’

‘The rest of your target comes from walking,’ adds Baah. ‘Just 40-50 minutes of brisk walking every day gets you there easily. Add a swim, yoga or dance class once a week if you like, and you’re all set.’

But don’t forget to adequately fuel, notes Baah. ‘Once you’re moving regularly, food matters, too. You need enough protein every day to help your body get stronger – aim for 1.4-1.8g for every kg of bodyweight. Without this, you do the work but miss out on the best results.’

If you’re more deterred than motivated by the recent study results, Horncastle wants to leave you with a few words. ‘Start small and slow, whether that’s one workout a week and building up, or starting with a few small walks – that’s how you achieve long-term, consistent change.’

‘And don’t compare yourself – who cares if Susan does hot yoga five times a week? She isn’t living your life. You need to find what works for and benefits you, but is realistic, too.’
