Do I Need To Get In Shape Before Starting Jiu-Jitsu?
If you've ever thought about trying jiu-jitsu but told yourself: "I need to get in shape first."
You're not alone.
Maybe it's been years since you've exercised consistently. Maybe you'd like to lose some weight. Maybe your cardio isn't what it used to be. Or maybe the idea of walking into a martial arts academy where you assume everyone else is already fit, strong, and experienced feels a little intimidating.
So you make yourself a deal:
I'll start once I lose 10 or 20 pounds.
I'll start after I get back into the gym.
I'll start when my cardio is better.
Here's the problem: You're trying to get ready for the very thing that can help you get ready.
You don't have to get in shape before starting jiu-jitsu. You just have to start.
Beginners Are Supposed to Be Beginners
One of the strangest expectations we place on ourselves as adults is believing we should somehow already be good at something we've never done.
We don't expect that from our kids. When a child starts a new sport, we expect them to need instruction. We expect them to get tired. We expect them to make mistakes. We tell them:
"Give it time."
"You're still learning."
"Nobody is good at something the first time they try it."
And then it's our turn to try something new, and suddenly those rules disappear.
Adults walk into their first jiu-jitsu class worried that they're too old, too heavy, too weak, too inflexible, or too out of shape. But that's exactly what a beginner is supposed to be: Wherever they are today.
You aren't expected to arrive ready for jiu-jitsu. Training is what gets you there.
Jiu-Jitsu Really Is a Workout
We don't need exaggerated fitness claims to make this point. There's actual research behind it. Brazilian Jiu-Jitsu is an intermittent sport, meaning periods of higher, moderate, and lower intensity occur throughout training and sparring. A systematic review examining 58 studies involving 1,496 participants looked at major physical components involved in BJJ, including aerobic and anaerobic fitness, muscular strength, power, body composition, and muscular endurance. Researchers also noted the particular importance of strength endurance because grappling requires athletes to repeatedly maintain muscular effort during training and competition.
In everyday terms?
You're moving.
You're pushing.
You're pulling.
You're gripping.
You're stabilizing.
You're getting up and down from the floor.
You're using your core.
And you're doing all of that while trying to solve the physical puzzle happening in front of you. It doesn't feel much like spending 45 minutes staring at the timer on a treadmill. And you certainly don't need an athlete's conditioning to begin developing those abilities.
What About Weight Loss?
This is worth talking about honestly because losing weight is one of the reasons many adults decide they want to become more active. Can jiu-jitsu be part of a weight-loss journey? Absolutely. But no exercise program—including jiu-jitsu—is a magic weight-loss solution.
The CDC explains that physical activity increases the amount of energy your body uses, while weight loss ultimately occurs when that contributes to a calorie deficit. Nutrition therefore matters too, and the amount of physical activity needed for weight management varies considerably from person to person.
That's why we'd rather tell you the truth than promise that jiu-jitsu will make a certain number disappear from the scale. What regular physical activity can do is much bigger than that.
The CDC reports that physical activity can improve sleep, reduce feelings of anxiety, strengthen bones and muscles, and lower the long-term risk of conditions including heart disease, stroke, and type 2 diabetes. That's a pretty compelling reason to move your body—regardless of what the scale says.
"But I Know I'm Going to Get Tired."
You probably will. That's okay. You may need breaks during your first classes. That's okay too.
Your first goal isn't to keep up with someone who has been training for five years. Your first goal is simply to begin. Then come back. And come back again.
Federal physical-activity guidance recommends that adults work toward at least 150 minutes of moderate-intensity aerobic activity each week, along with muscle-strengthening activity on at least two days. But importantly, the CDC also emphasizes that adults who are inactive can build toward those goals—and even some moderate-to-vigorous physical activity provides health benefits.
You don't have to transform your fitness overnight. You build it. One class at a time.
You May Be Surprised by What Changes
One of the great things about starting jiu-jitsu is that progress isn't always measured by a scale or a stopwatch. Sometimes you notice it when climbing the stairs doesn't leave you as winded. Or when you make it through another round before needing a break.
Maybe you realize you're moving more easily. You're stronger than you were. You're sleeping better. Or something that felt impossible during your first week suddenly feels...normal.
Those little changes add up.
And because jiu-jitsu is also something you're learning, the motivation can feel very different from exercising simply because you think you're supposed to exercise.
You're not just working out.
You're learning a skill.
The Hardest Part May Be Walking Through the Door
For many adults, physical fitness isn't actually the biggest obstacle.
It's being a beginner again.
It takes a little courage to walk into an unfamiliar room, put on a gi, and admit that you don't know what you're doing.
We understand that.
At Charles Gracie Academy Magnolia, we aren't looking for people who are already great at jiu-jitsu.
That's our job.
We want people who are willing to learn.
Our adult classes are designed to be welcoming to beginners, and our instructors will help you learn at an appropriate pace. You don't need previous martial arts experience. You don't need to be an athlete. And you certainly don't need six-pack abs.
You just need to be willing to take that first step.
Stop Waiting Until You're "Ready"
If you've been telling yourself you'll start when you're fitter, stronger, thinner, or more confident, consider this:
Maybe those aren't prerequisites for starting.
Maybe they're part of the journey.
We give our children permission to be beginners all the time.
Maybe it's time we gave ourselves the same permission.
You don't get in shape so you can start jiu-jitsu.
You start jiu-jitsu—and getting stronger, healthier, and more capable can become part of the journey.
Maybe This Is Your Sign to Start
If you've been thinking about trying Gracie Jiu-Jitsu, we've made it a little easier to finally say yes.
For a limited time, new adult students at Charles Gracie Academy Magnolia can train September through December for $500—and we'll include your Charles Gracie gi FREE.
Sign up now, and you can train the rest of August free.
Four months.
A new gi.
A chance to learn something new.
And maybe the beginning of a stronger version of yourself.
You don't have to get ready first. Come as you are. We'll start from there.
