The Trader’s Performance Edge with Dr. Julie Manz

Because the most important edge you will ever develop is not in the market. It is in yourself.

I may lose a few people with this one.

The minute I start talking about exercise, I know some traders are thinking, Julie, I came here to learn how to trade. What does going for a walk have to do with my P&L?

More than you might think.

Because this article is not really about exercise. It is about performance capacity—your ability to stay focused, regulate emotion, adapt when conditions change, and continue making good decisions when the market puts you under pressure.

And that makes exercise very much a trading topic.

The Performance Connection: Your Brain Is Part of the Trading System

Traders will spend thousands of dollars improving almost every part of their trading environment.

Faster computers. Better monitors. Premium market data. New software. News services. Indicators. Education. Coaching.

Yet we sometimes neglect the one piece of equipment responsible for interpreting every bit of that information and making every trading decision.

Ourselves.

Your brain is not separate from your trading system. It is the part of the system that decides whether to enter, wait, add, exit, follow the stop, ignore the noise, or chase something you probably should have left alone.

So when we talk about physical health in the Manz Performance Model, we are not suddenly changing the subject.

We are talking about maintaining the machinery behind execution.

The Hidden Performance Drain: Cognitive Fatigue

Trading may not look physically demanding, but mentally it can be exhausting.

Think about how many small decisions happen during an active session.

Is this setup ready?

Is that move real?

Should I wait another bar?

Is the market confirming the trade?

Should I take the target or let it work?

Am I following my plan—or reacting emotionally?

Each decision draws on attention, working memory and executive control. Psychologists often group these demands under the idea of cognitive load.

You may not notice the fatigue accumulating because you are sitting in a chair. But your decision-making system notices. That is one reason a trader can be patient and disciplined at 9:45 in the morning and considerably less patient at 1:45 in the afternoon.

The strategy may not have changed. The condition of the person executing it has.

That distinction matters.

One of the biggest mistakes traders make is assuming every execution problem is a strategy problem. Sometimes the real problem is fatigue, stress, poor recovery, lack of movement, or simply too many uninterrupted hours of decision-making.

Why Movement Matters to a Trader

Exercise does much more than strengthen muscles or burn calories.

Regular physical activity is associated with better attention, working memory, mood regulation, stress resilience, executive function and cognitive flexibility.

That last one—cognitive flexibility—is particularly important in trading.

Markets change.

A stock that looked strong five minutes ago can suddenly lose momentum. A breakout can fail. A broad-market move can completely change the character of an individual setup.

Good traders adjust when the evidence changes.

Poor decisions often happen when we become mentally attached to what we expected to happen.

Exercise cannot make those decisions for you, of course. But it can support many of the mental systems you rely on when making them.

That is the real connection between exercise and trading performance.

The Brain Learns Through Movement Too

One interesting piece of exercise research involves Brain-Derived Neurotrophic Factor, or BDNF. I like to think of BDNF as part of the biological environment that helps the brain learn, adapt and maintain healthy neural connections.

Physical activity influences BDNF and other processes associated with neuroplasticity—the brain’s ability to change through experience.

Why should a trader care?

Because trading is largely a learning problem. You are learning to recognize patterns. You are learning which signals matter and which ones are noise. You are learning to recognize when a setup is behaving normally and when something has changed.

And, perhaps most importantly, you are learning how you behave under uncertainty.

All of that depends on a brain capable of learning and adapting. A healthier brain gives that process a better foundation.

Exercise Also Teaches You Something About Discomfort

This may be the most interesting connection of all. Exercise creates controlled discomfort.

Walk briskly uphill and your breathing changes. Lift something challenging and your muscles begin to fatigue. Hold a difficult yoga position and your body starts asking how much longer this is going to continue.

Your nervous system becomes activated.

But over time, you learn an important lesson: Discomfort does not automatically mean danger.

That lesson transfers surprisingly well to trading.

A position moves against you. Volatility suddenly increases. Your heart rate rises. You feel the urge to do something. The question is whether you can experience that physiological response without immediately turning it into a trading decision.

Elite traders are not people who never feel stress. They are people who become better at functioning while stress is present.

Exercise gives us another place to practice that skill. You notice the elevated heart rate. You notice the discomfort. You stay engaged. You assess what is actually happening.

And you learn that activation and panic are not the same thing.

That is a very useful lesson to bring into the market, using exercise to increase your trading performance

What This Looks Like for Us

Adrian and I try to take a walk with the dog after roughly the first hour and a half of trading. I have come to appreciate that walk as much for what it does mentally as physically.

It creates a clean break between periods of concentration. We get away from the screens. We move. We talk. The nervous system gets a chance to settle and the brain gets a chance to stop processing market information for a little while.

Then we can come back. That reset matters.

We also exercise regularly, but I have become much less rigid about what I think exercise is supposed to look like.

Some days that means cardio. Some days it means strength training. Sometimes it means yoga. Sometimes walking is enough.

The goal is not to win an award for having the perfect workout. The goal is to keep the performer capable of performing.

That becomes increasingly important as life changes. We get older. Responsibilities grow. Recovery changes. Stress outside the market finds its way into the trading room whether we invite it or not. What worked effortlessly at 25 may require more intention at 45, 55 or 65.

I do not think that is failure, I think that is adaptation. And adaptation is one of the central skills of high performance.

You Do Not Need to Become a “Gym Person”

This is where people sometimes make exercise unnecessarily complicated.

You do not need to run a marathon. You do not need a two-hour workout. You do not need the perfect heart-rate zone, the perfect fitness tracker or the perfect program.

Walk.

Ride a bike.

Lift weights.

Swim.

Stretch.

Take a yoga class.

Garden.

Dance.

Play pickleball.

The best form of exercise is not necessarily the one that looks most impressive, it is the one you can turn into a repeatable part of your life.

Because for performance, consistency usually matters more than occasional intensity.

A heroic workout followed by six days on the couch is not much of a system. Neither is one day of perfect trading discipline followed by four days of impulsive decisions.

Performance tends to be built through repeatable behaviors and exercise positively affects your trading performance.

Exercise Is Not Time Away From Performance

Busy professionals often see exercise as something that competes with productive work. I think that calculation is incomplete.

If 30 minutes of movement helps you think more clearly during the next several hours, then those 30 minutes were not necessarily taken away from productivity. They may have improved it.

That is particularly important for a trader because one poor decision made while mentally depleted can undo a lot of good work.

We spend enormous amounts of time trying to find better entries. Sometimes we should also be asking: What helps me become the person most likely to execute those entries correctly?

That is the larger idea behind Physical Insight.

The Performance Loop

One of the reasons I like exercise as part of a performance model is that the benefits tend to reinforce one another.

Regular movement can support energy, mood, stress regulation and sleep. Those can support better focus and patience. Better focus and patience can support better execution. Better execution tends to increase confidence in your process.

And confidence in a sound process can make it easier to avoid emotionally driven decisions.

So the relationship is not:

Exercise → profitable trading.

It is closer to:

Movement → better performance capacity → better conditions for disciplined execution.

That is an important distinction. Exercise will never replace a trading edge. But it can help support the person responsible for executing one.

Julie’s Performance Challenge

This week, I want you to run a very simple experiment.

Move intentionally for at least 30 minutes each day.

Do not worry about calories. Do not worry about whether it was difficult enough. Do not worry about whether someone else would consider it a “real workout.”

Walk. Stretch. Lift. Ride. Practice yoga. Put on some music and dance around. Go up and down stairs.

Just move.

Then, before the market opens—or before beginning your main work period—give yourself a score from 1 to 10 for three things:

Focus

Patience

Calm

You might also make a quick note about whether you exercised the previous day, how you slept and how you feel physically.

At the end of the week, look back. Do not try to prove anything. Just look for patterns. You may find that the market did not change at all.

But the person responding to it did.

Julie’s Toolbox

Every elite performer has tools that make good habits a little easier. These are not necessities. They simply reduce friction.

A Comfortable Pair of Walking Shoes

Walking remains one of the easiest forms of exercise to fit into a trading day.

A comfortable pair of shoes removes one tiny excuse. They make it easier to get outside after the morning session, take a short reset walk or simply add movement to a day that might otherwise be spent sitting.

Resistance Bands

Resistance bands are inexpensive, portable and surprisingly versatile. They make it possible to add basic strength work almost anywhere—at home, in an office or while traveling—without needing much space or equipment.

Julie’s Book Corner

Spark by John J. Ratey, M.D.

This is one of the books that helped change the way many people think about exercise.

Rather than treating movement strictly as a fitness issue, Dr. Ratey explores its relationship with learning, mood, memory, stress and cognitive performance.

That makes it particularly relevant to the way I want traders to think about exercise: not simply as something we do for the body, but as something that can support the brain doing the trading.

Healthy Brain, Happy Life by Wendy Suzuki, Ph.D.

Neuroscientist Wendy Suzuki takes a similarly interesting look at the connection between movement and the brain.

She combines research with personal experience to explain how physical activity can influence memory, attention, mood and brain health.

The Science Behind the Insight

The research does not suggest that exercise somehow turns people into better traders.

That is not the claim.

What it does suggest is that physical activity can support several systems involved in high-quality performance: attention, working memory, executive function, cognitive flexibility, mood regulation, stress response, neuroplasticity and healthy aging.

Those are also systems traders use every day.

So the practical argument is fairly simple. If trading requires sustained cognitive performance, then maintaining the physical systems supporting cognition deserves to be part of trading preparation.

One Thing to Think About

Imagine someone offered you a pill that might help support: better focus, better emotional regulation, better memory, better stress resilience, better sleep, and healthier cognitive aging.

You would probably want to know more about it.

You might even be willing to pay quite a bit for it.

Now imagine that one of the things that can support many of those same systems is something as ordinary as taking a walk. Sometimes the performance tools we overlook are the simplest ones.

One Final Thought

People often ask what separates elite performers from everyone else. Usually they are looking for a secret.

More talent.

More intelligence.

More discipline.

A better strategy.

Those things can matter.

But elite performers also learn to prepare the performer.

They recognize that execution does not happen in isolation. Sleep matters. Nutrition matters. Stress matters. Movement matters. Recovery matters.

The market is where your performance eventually gets measured. But much of that performance is built somewhere else. It is built in the choices you make before the trading day begins, after the screens go dark and during the hours when nobody is watching.

So the next time you think taking 30 minutes to exercise is pulling you away from your trading, consider another possibility. It may be part of your trading preparation.

Until next time, trade well, think clearly and take care of the performer behind the performance.
