HIT THE SWEET SPOT

It’s an equation more complex than Euler’s theorem: how to harness the energy-boosting benefits of exercise without crashing a few hours post-session. Problem. Solved

Find a workout routine that’s just right for your energy levels

When it comes to exercise and energy, comprehending the relationship between the two is trickier than running a bath at the perfect temperature. Exercise requires energy to perform – and has been proven to provide a boost if you do it right. But sweat too much and you’ll end up knackered, swerve sessions entirely and be too lethargic to even pull your leggings on.

‘Studies show an improvement in energy levels after exercise,’ confirms Tracey Devonport, professor of applied sport and exercise science at the University of Wolverhampton. ‘Previously, this was attributed to the release of chemical endorphins – hormones that elevate mood and help fight fatigue – but new research suggests other chemicals such as noradrenaline, dopamine and serotonin (produced and released in higher concentrations during exercise) may be responsible.’

But how to boost your power bank without tipping into tired AF territory? ‘Moderate-intensity exercise is associated with an increase in perceived energy, while vigorous exercise raises the risk of exhaustion,’ explains Devonport.

So, best practice is experimenting to find where that sweet spot between moderate and vigorous sits for you, and aiming for it on days when you’re feeling more like lying down than leaning in. To that end, we tapped celebrity trainer and founder of Roar Fitness Sarah Lindsay to create an exercise plan that should help give you a lift akin to a post-glastonbury shower.

THE WORKOUT Sarah’s plan combines strength and cardio. ‘This way, you won’t fatigue one energy system by repeating the same type of workout too soon,’ she says. ‘Variation keeps you mentally stimulated, too.’ Aim to mix 2-3 strength sessions with 2 cardio sessions across the week for max results.
