While exercise is known to improve memory, scientists have mostly studied this effect by using behavioral tests or brain imaging methods like MRIs, says Michelle Voss, PhD, one of the study’s authors, a professor, and the director of the Health, Brain, and Cognitive Lab at the University of Iowa in Iowa City.
But she says these approaches can’t precisely identify where “ripples” originate, particularly in the deep brain structures like the hippocampus, a part of the brain strongly connected to memory and learning, she says.
The current study, published in Brain Communications, recorded electrical activity directly, using surgically implanted (intracranial) electrodes. “This allowed us to observe how exercise changes the brain’s memory circuits in real time,” Dr. Voss says.
The participants performed a 5-minute warm-up and then rode a stationary bike for 20 minutes at a pace they could maintain. Researchers recorded their brain activity before and after the biking session.
The electrodes showed an increased rate of so-called sharp-wave ripples from the hippocampus and connections with cortical regions of the brain, which are involved in learning and memory.
“Sharp-wave ripples have long been known from animal studies to play a central role in memory,” Voss says, adding that recent studies using intracranial recordings in humans also support the importance of ripples for human memory.
“Our findings are the first to show that exercise can modulate these ripple signals in the human brain,” she says.
Researchers also observed that larger increases in heart rate during exercise were associated with larger changes in ripple activity in cortical networks, Voss adds.
Exercise helps build connections between neurons, which deepens and strengthens brain networks, Franssen says.
Physical activity also improves metabolism, which improves insulin sensitivity, helping blood sugar regulation and giving the brain a “more stable and reliable supply of fuel,” Dr. Perlmutter says.
“This is critically important because the brain is an energy-intensive organ, consuming roughly 20 percent of the body’s energy despite representing only a small fraction of body weight,” he adds.
Voss says researchers were careful to “exclude signals that contained epileptic activity. However, of course, we can’t statistically control for the accumulated effects of having epilepsy on the brain.”
The exercise-brain ripple patterns observed in the current study also closely match those observed in healthy adults using noninvasive brain imaging, such as MRI, she added.
“That convergence across very different methods is one of the strongest indicators that the effects are not specific to epilepsy, but reflect a more general human brain response to exercise,” Voss said.
Researchers also didn’t directly test memory performance, Voss notes. “While hippocampal ripples are strongly linked to memory processing in decades of neuroscience research, the next step will be to measure how exercise-related changes in ripples relate to memory performance in the same individuals.”
Future studies should also compare exercise with other everyday activities, such as sitting quietly or light movement, to determine how specific these effects are to aerobic exercise at the intensity that was studied, she says.
It’s never too early or too late to start exercising for brain health, Franssen says.
People of any age, from grade-school children to people in their nineties, can benefit from increased physical activity, Perlmutter says. “My recommendation is to consider taking advantage of the connection between physical activity and brain health across the entire range of human aging.”
Any type of exercise is great, Franssen says, but especially “repetitive behaviors,” like swimming, jogging, and walking.
“Sometimes we let the hugeness of putting in a huge fitness routine get in our way,” she says. “Having a little exercise snack every so often is also very important to improving cognition.”
“Dancing With the Stars” alum Lindsay Arnold is expanding her digital fitness universe with the launch of a home exercise tool, The Everything Band.
Out now, the all-in-one, multiloop resistance band is a first-of-its-kind product designed to replace clunky gym equipment such as reformers, leg machines, rowers, kettlebells and more. With 11 loops (five “levels” on each side of the center loop), the portable tool, $35, can assist more than 100 movements, all of which are modeled in Arnold’s four-week, low-impact Tone Program, available on The Movement Club app.

Speaking with WWD, Arnold described the band as a physical manifestation of her need to multitask. “I like to get things done. I like to be efficient with my time. And anything I create is going to be kind of a physical version of that,” she said. “The Movement Club is our digital version of that. It’s accessible movement that people can truly do anywhere. So when we decided to go into the physical product space, I knew I wanted something that’s multifunctional, that is versatile, that is innovative.”
Arnold founded the membership platform in 2020, after her 10-year run as a coach on “Dancing With the Stars.” The idea was born out of a sudden change in her own fitness regimen that occurred when she was pregnant with her first baby. “My body was my tool to perform, but when I stepped away from that career and became a mom, life looked a lot busier. I didn’t have as much time to get back to myself,” she recalled.
“I started looking at fitness in a different way,” she continued. “I felt like there was a missing space in the fitness industry for a program that’s for everyone, not a program that’s only for pregnant women or only for people in the best shape of their life, but truly a program that meets people exactly where they are at in their fitness journey.”

In 2025, The Movement Club saw a 190 percent increase in revenue, a 226 percent increase in new subscribers and 151 percent growth spike in returning subscribers.
With 12 programs including Full Body, Bridal, Postpartum, Pilates Strength and Self Care, the membership-based platform is, indeed, suitable for beginners, experts and every exercise level in between. Most workouts range from 18 to 30 minutes, with elements of dance woven throughout. “A lot a lot of my classes incorporate ballet, bar movements and also the stretching that I do feel like is a lot more targeted for dancers, which is really, really cool, because it’s all about lengthening and strengthening your muscles while also stretching and keeping your body safe,” Arnold explained.
The Tone Program, which is five days on and two days off, targets arms, glutes, legs and core, with short, high-intensity intervals and three-to-four reps of each exercise. The format, Arnold said, allows members to familiarize themselves with the band, and hopefully, inspire them to use it in their own regimen. “I will continue to add new videos with the band, like I always do, but first, I really wanted to launch with a good program for people to follow along with and track their progress,” she said.
The weekend workout trend is taking over the internet, and people are obsessing over it. But with most of us leading sedentary lives, is it too good to be true? HT Lifestyle spoke with Sumit Dubey, fitness expert and the founder of Sumit Dubey Fitness (SDF) centre to understand whether weekend exercise actually works or it is just another passing fad.

Sumit Dubey said, “These days, life moves quickly. Folks find it tough sticking to regular workouts through the week. So they shift everything to Saturday and Sunday instead.” “Squeezing sweat into just a couple of days has become common lately,” he added.
“When Monday hits, and the chairs stay full again. Two long pushes each weekend. Can those really balance out five lazy ones after? The body keeps score differently, maybe,” said Sumit.
According to Sumit, weekend movement counts more than you might think. Scientists see gains when people hit 150 weekly minutes of solid effort, even if it’s just two days. Hearts respond well, so do blood sugar levels. Long-term illness risks dip slightly, and doing something beats doing nothing – no perfect routine needed.
Still, some key limits need attention. Sumit highlighted that often moving keeps things running smoother. When you stay seated all day, circulation slows, posture slips, body parts weaken – little by little, they lose their edge. Five inactive days dull the gains from two active ones. A weekly rhythm matters more than weekend effort alone.
Here’s another thing to think about: getting hurt more easily. When exercise gets squeezed into just a few minutes, people tend to go too hard – especially if they haven’t moved much lately, highlighted Sumit. Pushing fast without building up slowly can pull muscles or strain joints. Tiredness shows up quicker when effort spikes out of nowhere. Bodies unprepared for sudden bursts react with soreness or discomfort most times.
“Still, working out on weekends might actually help, as long as it’s done with some thought,” said Sumit. Ease counts more than effort. You can try running, sometimes swimming instead; pair either with strength drills along with quick footwork. Wait until movement feels smooth before adding speed, ease off gradually once finished.
Mornings aren’t the only time motion matters. Getting up to stroll, reach, or shift positions through workdays cuts down the health downsides of too much stillness.
“Just twice a week, moving your body? That still misses what everyday motion offers. Showing up – any way you can – is more crucial than how hard you push. Consistency wins easily when matched against sporadic bursts. Skip perfect routines; choose ones that fit smoothly into life. Progress forms slowly, built by tiny actions done again and again,” said Sumit.

Vernon’s favourite senior’s personal trainer is on the move. For more than 25 years, Don MacLeod has been leading weight-resistance exercise classes for seniors.
Vernon’s favourite senior’s personal trainer is on the move.
For more than 25 years, Don MacLeod has been leading weight-resistance exercise classes for seniors.
And for the past eight years, MacLeod had taught classes five days a week at Snap Fitness in the Landing Plaza, but on March 31 that gym closed its doors, so MacLeod needed a new venue for his popular classes.
Enter Anytime Fitness in the Anderson Subdivision.
MacLeod said he is grateful to have reached a deal with the fitness club to carry on his morning exercise classes, and many seniors have already signed up.
While there are other gyms in Vernon that have seniors exercise classes, the certified personal trainer uses weight-resistance training to target all major muscle groups.
He will lead seven classes from Monday to Friday.
“It’s basic strength training,” MacLeod said of the exercises that geared towards the older crowd.
“We do everything that the bodybuilders and powerlifters do, but in a reasonable manner where we are just going to get our bones, our muscles, our tendons and ligaments stronger.”
MacLeod, 71, has also taken special courses geared specifically towards working with seniors.
Some seniors may feel too intimidated to go to a gym on their own, but MacLeod said seniors can find a common bond when they exercise in a group.
MacLeod said he has heard a few people say “what a waste of space” to hold senior’s classes.
“They really make life difficult for us. They think old people shouldn’t be in the gym, why are they lifting weights: to stay strong and to stay healthy,” MacLeod said. “One day, these guys are going to be old too.”
MacLeod said he started lifting weights in 1972 and continues to reap the benefits of regular exercise as he enters his 70s.
For more information, contact MacLeod at 250-260-1001.
