Why Fitness Advice Is So Confusing (and What to Do About It)

Why Fitness Advice Is So Confusing (and What to Do About It)

Learning about exercise can be overwhelming. One YouTube channel tells you what to do, and you think, OK, I’ve got that. Then you see an Instagram post that tells you something else entirely. Stop by the gym and ask a trainer, and they’ll let you know that both of your sources are overthinking it and instead you should do things their way. Why is it all so complicated? I have some thoughts on that, and some tips for navigating the confusion.

One of the biggest reasons is that there are many good answers for each of your fitness questions. So you don’t have to find the one true correct answer before doing your workout, any more than you’d need to identify the unquestionably best restaurant in town before going out to eat. Let’s dig in to some of the types of confusion that you’re probably running across, and what to do about each.

Not everybody is talking to you

First I’d like to address the biggest reason we see conflicting advice in any subject: Different experts are talking to different audiences. You, the reader or viewer, are not in all of those audiences at once.

For example, if you search for “how to squat,” you’ll find a variety of answers to the question. One expert might have advice for bodybuilders to build as much leg muscle as possible. Another might be telling powerlifters how to get strong and move the most weight in competition. Yet another might be introducing beginners to the idea of exercising at all. It makes sense that they would all say different things, right?

How to navigate this: Decide on a type of advice to follow. If you want to learn the basics of powerlifting, for example, there are books and videos and real life human coaches who will teach it to you. And if you’re a beginner, don’t seek out advice for advanced lifters; it won’t be helpful to you yet.

If you can’t decide what direction you’re doing, it’s fine to check out different sources and see what they each say. But don’t expect them to all agree with each other.

The algorithm rewards pointless debates

The basics of training are pretty simple, even if it may not seem that way when you’re a beginner. You get better at running by putting in time on your feet, and not trying to turn every training run into a race. (See our beginners’ guide here.) You get stronger by lifting heavier weights over time, although that doesn’t have to mean lifting more every single week—best to follow a program that guides you through a sensible path for progress. And if you’re brand new to everything, all you really need is to build a routine and not give up; literally all of the details can wait.

But we like to learn more, and if we’re confused or anxious, we often think the cure is more information. So we visit YouTube (or the information firehose of our choice) and see what it has to say. But here is where the algorithm stands in our way: YouTubers don’t have much of a career if they just put out a few videos with basic information and then sit back and relax.

So we get in-depth debates on things like: Which running shoe might be marginally better than another? Should you do your morning workout before or after breakfast? Should you do dumbbell lateral raises with your hands in a neutral position or with your pinkies pointing slightly upward? (You might think I’m joking with that last one, but it has become a hugely controversial subject.)

Creators also get more engagement if they react to other creators, cultivate rivalries, say that everyone else has it wrong, debate creators with the opposing viewpoint, etc. The algorithm rewards confusion, because it makes people watch more videos. In reality, the direction of your pinkies on lateral raises is going to make, at most, 0.0000001% of the difference in how your shoulders look a year from now. Even if you could get a solid answer on which way is best, it wouldn’t actually matter.

How to navigate this: One day I was typing the word “optimal,” and my phone auto-corrected it to “optional.” That’s a life lesson right there. Optimal is optional. If you’re doing things basically good enough, optimizing the details is going to make very, very little difference. When you are an Olympic athlete and tiny differences in your performance could make or break your chances for a gold medal, you can revisit these questions. For now, just remember that there are many paths toward fitness, and you can take whichever you find simplest or most enjoyable.

Most advice is meant to nudge you in a direction

Let’s step out of the social media algorithm for a moment, and talk about the very reasonable things you might hear from a trainer.

As a trainer is trying to guide your movement, they’ll give you cues. These are not meant to be objective descriptions of exactly what happens in a lift, but rather nudges in a particular direction. For example, if your heels pull off the ground as you are squatting, you might be told to “drive through the heels.”

This can lead to confusion if you hear another trainer say to “keep even pressure on all parts of your foot.” That would be a better cue for somebody who is tipping back onto their heels, but it could work for the person who is getting up on their toes as well. The truth is that both trainers are trying to do the same thing: keep you from rocking too far forward or backward.

Since cues are nudges, they can’t really be right or wrong; they can just be helpful or unhelpful. The cue that works for someone else may not be the right cue for you.

How to navigate this: Ask for clarification if you’re getting the advice in person. If not, try both of the conflicting cues, and see if one of them helps you to feel stronger or do the movement better. You may also want to read our explanations of the cues that tend to confuse people most.

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Exercise Boosts Brain ‘Ripples’ Tied to Learning and Memory

Each time you go for a jog, ride your bike, or get active in other ways, you’re giving your brain a boost. A small new study has for the first time directly documented this phenomenon, which the researchers call “ripples” — brief bursts of electrical activity in a part of the brain called the hippocampus.

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.

20-Minute Bursts of Exercise Increase Brain Ripples

To conduct the study, the researchers recruited 14 participants between ages 17 and 50 with drug-resistant epilepsy. The subjects had already been fitted with intracranial electrodes as part of their preparation for surgical epilepsy treatment.

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.

What’s Already Known About Exercise, Memory, and Learning

“We know that exercise is the number-one thing we can do to enhance our memory and learning,” says Catherine Franssen, PhD, an assistant professor in the School of Life Sciences and Sustainability at Virginia Commonwealth University in Richmond. “Exercise will enhance both our ability to learn new things and our ability to remember previously learned things.”

Movement helps pump oxygenated, nutrient-rich blood to the brain, says Dr. Franssen, who was not involved with the new study: “We’re able to activate those brain cells more effectively and energize them.”

The increased blood flow stimulates the growth of new neurons and enhances the production of brain-derived neurotrophic factor (BDNF), a molecule that strengthens connections between brain cells and supports learning, says the neurologist David Perlmutter, MD, who was not involved with the latest study.

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.

The Research Has Limitations

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.

Satisfy Your Brain’s Exercise Craving

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.”

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Higher Fitness Levels Amplify Brain Benefits After Exercise, Study Finds

Increasing our level of physical fitness leads to a bigger release of brain-boosting proteins following one session of exercise, a new study led by a UCL researcher has found.

The study, published in Brain Research, took a group of inactive unfit participants through a 12-week training programme of cycling three times per week and made them fitter. Researchers found as their fitness increased, so did the amount of brain-derived neurotrophic factor (BDNF) released following exercise, resulting in improved brain function.

Just 15 minutes of moderate to vigorous aerobic exercise releases BDNF, a brain protein which is known to support the formation of new neurons and new synapses (connections between brain cells), and maintains the health of existing neurons. This is the first study to show that for unfit people, just 12 weeks of consistent training can boost the brain’s response to a single 15-minute workout.

The study, led by Dr Flaminia Ronca (UCL Surgery & Interventional Science, and the Institute of Sport, Exercise and Health), involved 30 participants – 23 male and seven female – taking part in the 12-week programme. To assess fitness levels throughout the programme, participants completed VO2max tests every six weeks, which measures the maximum rate of oxygen your body can consume and use during intense exercise.

BDNF levels were measured pre- and post-VO2max testing, alongside a series of cognitive and memory tests, while also measuring changes in brain activity in the prefrontal cortex – where executive functions such as decision-making, emotion regulation, attention and impulsivity are controlled.

By the final week of the trial, results showed that baseline levels of BDNF did not change, but participants did show a larger spike of BDNF following intense exercise, compared to how their brains responded to intense exercise before the 12-week programme. This was linked to improvements in VO2max (aerobic fitness).

Higher overall BDNF levels and stronger exercise-induced increases were also associated with changes in activity across key areas of the prefrontal cortex during attention and inhibition tasks, though not during memory tasks.

Overall, the results showed that increasing physical fitness can enhance the brain’s ability to produce BDNF in response to acute bouts of exercise, which can have a strong positive influence on neural activity.

Lead author Dr Flaminia Ronca said: “We’ve known for a while that exercise is good for our brain, but the mechanisms through which this occurs are still being disentangled. The most exciting finding from our study is that if we become fitter, our brains benefit even more from a single session of exercise, and this can change in only six weeks.”
