How Exercise Affects Sleep and Energy in Your 50s and 60s
There's a particular sort of morning worth aiming at. You surface before the alarm, you don't negotiate with the duvet, and by three in the afternoon you've still got something in the tank.
That's what I want to get into: exercise, sleep and energy for the over 50s. I run online exercise classes across the UK, and once people have been coming a while, sleep is the thing they mention without being asked.
Sleep and energy are the same problem
They look like two separate things. They're one thing seen from either end.
There's a state I think of as the zombie. Never properly asleep, never properly awake. Drifting through the evening, then drifting through the next day as well. Nothing wholehearted at either end of it.
Watch someone in their twenties. They're either out like a log or bouncing about like a labrador puppy. Both of those are wholehearted states, and that's the bit that matters. Depth at night, proper go in the day.
Rest is training, and training helps you rest.
I won't pretend sleep stays easy for everyone. I look back at my teenage self sleeping until two in the afternoon with real envy. But the way out of the zombie isn't waiting for sleep to turn up of its own accord. It's earning it.
That's what exercise does. You earn your sleep, then you've got more in the tank while you're awake.
What better sleep actually means here
Better sleep, in the research and in practice, mostly isn't about more hours.
It's falling asleep sooner. Waking less in the night. More of the time you spend in bed actually spent asleep.
Which is exactly what sleeping like a log describes. Not a longer night. A more solid one.
What the research says about exercise, sleep and energy over 50
The biggest piece of work here is a 2025 network meta-analysis in BMC Geriatrics by Xiong and colleagues. They pooled 62 randomised trials covering 5,005 older adults, then ranked exercise types against each other for sleep quality. Combined aerobic and resistance training came out on top, ahead of aerobic alone, resistance alone, walking and yoga. Improvements showed up from around five weeks in.
For what that looks like measured rather than reported, there's a 2026 randomised trial in the Brazilian Journal of Physical Therapy from Monteiro and colleagues. Thirty-two older adults, average age 70, sixteen weeks of mixed training, with sleep tracked by a wrist monitor rather than a questionnaire. More of their time in bed was spent asleep, a rise of about 6.6 percentage points, and they were awake in the night roughly 33 minutes less. Their sleep got less broken up.
Total sleep time didn't move. Neither did time in bed. So look at what did shift: not the night's length, its solidity.
A 2020 trial in the Journal of Clinical Sleep Medicine by Tseng and colleagues points the same way. Forty adults, average age 62, all of them sleeping badly at the start. Twelve weeks of supervised aerobic work three times a week, and their sleep quality scores improved across every part of the measure.
They recruited people who weren't sleeping well to begin with. If your sleep is already sound, there's less for exercise to shift.
Daytime energy has thinner research behind it than sleep does, so I'd call it promising rather than settled. What I can say is what I see once people have been turning up a couple of months.
Ursula said it best: "Love James classes in the morning. We have a great work out and it's fun and sets me up for the day."
If sleep has been a real struggle for a while, book a chat with your GP. Things like sleep apnoea need looking at properly, and moving more sits alongside that rather than instead of it.
Does it matter when you exercise?
Earlier in the day is a sensible default if evening sessions leave you wired. Some finish at eight and lie there with their brain still going.
Plenty of others sleep soundly after an evening workout and swear by it.
So no cut-off times from me. Try both, notice which gives you the better night, and go with that one.
What to actually do about it
Two things, neither complicated.
Something aerobic you'll come back to. Anything that has you breathing harder counts, and the research rewards repeatable over heroic.
Then some strength work alongside it, because that pairing is what ranked top in the Xiong review.
Then the thing that beats any perfect programme: turning up regularly. Five weeks is roughly where the shift starts, so consistency does more than cleverness.
The class timetable has 15+ live classes a week on Zoom. Fitness and Strength, Zumba Gold with Row, Yoga with Virginia, Pilates with Aimie, Tai Chi with Andy, Dancercise with Anna, and Balance. Many have seated and standing options. There are 1,000+ on-demand workouts too, for when live doesn't fit.
I film it all from a studio near Stroud, Gloucestershire, but Jim's Gym is online, wherever you are in the UK.
Questions people ask about exercise and sleep
Does exercise help you sleep after 50?
Exercise does help you sleep after 50, and the strongest evidence is for sleep quality rather than sleep length. A 2025 BMC Geriatrics review pooling 62 randomised trials and 5,005 older adults found combined aerobic and resistance training ranked best, with improvements appearing from around five weeks of regular training.
How long does it take for exercise to improve sleep?
Improvements tend to appear from around five weeks of regular exercise, according to the 2025 BMC Geriatrics network meta-analysis of 62 trials. Some people notice a difference sooner. The review found benefits still building well beyond that point, so those early weeks aren't the whole story.
Is it bad to exercise in the evening?
Evening exercise isn't bad for sleep as a rule, and plenty of people sleep well after a late session. If you finish a workout wired and then struggle to settle, move your sessions earlier and see whether that helps. There's no single cut-off time that applies to everybody.
What type of exercise is best for sleep?
Combined aerobic and resistance training ranked best for sleep quality in the 2025 BMC Geriatrics review of 62 randomised trials, ahead of aerobic work alone, resistance alone, walking and yoga. In practice that means something that lifts your breathing, plus some strength work, in the same week.
Will exercise give me more energy during the day?
Daytime energy has less research behind it than sleep does, so treat it as promising rather than proven. What's better established is that regular exercise improves how solidly you sleep, and sleeping more soundly is the usual route to having more in the tank by the afternoon.
