Most people think about warming up their muscles before a workout. Almost nobody thinks about warming up their nervous system. It turns out that might be the more useful place to start.
What breathing actually does to your body
When you feel stressed, rushed, or on edge, your body is running on its sympathetic nervous system, the part responsible for the fight or flight response. According to the American Council on Exercise (ACE), slow, controlled breathing helps activate the parasympathetic nervous system instead, the part of your body responsible for rest and recovery processes. [1]
Breathing through your nose specifically plays a role here. ACE notes that nasal breathing warms, moistens, and cleans the air before it reaches your lungs, and it stimulates the parasympathetic nervous system in the process. [1]

Why this matters before you train
You do not need to be in a state of full panic for this to apply. Everyday stress, a rushed morning, a stacked schedule, a stressful call right before your workout, keeps your sympathetic nervous system a little more active than it needs to be. Starting a workout in that state is not wrong, but a short reset beforehand can shift how your body shows up for the session.
A simple way to put this into practice
Before your next session, take a few minutes to inhale through your nose and exhale fully. Try counting a slow four count in and a slow four count out, and let your belly expand as you breathe rather than just your chest. That simple reset is enough to bring your stress response down before you begin.
This is not about doing it perfectly. Even one minute of this before you train counts.

Building the habit with iFIT
A good moment to try this is right before you open the iFIT Personal Trainer App to start your session. Use those few minutes between deciding to work out and actually starting as your breathing window. It costs nothing and takes less time than lacing up your shoes.
Frequently asked questions
Does breathing before a workout actually do anything?
Yes. Slow, controlled breathing helps activate your parasympathetic nervous system, which is associated with rest and recovery, and can help shift your body out of a stressed state before you begin training. [1]
Why breathe through your nose instead of your mouth?
According to ACE, nasal breathing stimulates the parasympathetic nervous system, in addition to warming and filtering the air before it reaches your lungs. [1]
How long do I need to do breathing exercises for it to help?
Even a minute or two of slow, controlled breathing before a workout can help calm your stress response. You do not need a long or perfect routine for it to count. [1]
When is the best time to do this?
Right before you start training works well, but it can also help during a stressful moment earlier in the day, before a meeting, while stuck in traffic, or anytime you notice tension building. [1]

iFIT Trainer Casey Gilbert Shares His Journey to Well-Being
May marks Mental Health Awareness Month, a time to fight the stigma, raise awareness, and support the millions of people around the world living with mental health conditions. We spoke with iFIT Trainer Casey Gilbert, who shared what mental health means to him, challenges he’s faced, and how it inspires his fitness journey. To learn more about Casey, follow him and iFIT on Instagram. And be sure to take care of yourself with our TBD Mental Health Collection, featuring refreshing workouts that support your physical strength and emotional well-being. Casey, how has prioritizing your physical fitness and mental health affected your overall well-being? Casey: “I started prioritizing my physical fitness because it was something that made me feel good, made me feel calm, and made me feel productive. But I didn’t realize until a few years ago that I was also prioritizing my mental health. There’s been plenty of times when, if I’m stressed or anxious, I don’t find myself able to perform physically. Taking moments to breathe, be mindful, and check in with yourself can benefit your physical health. Taking a step back sometimes can help me move forward in my fitness journey.” What inspired you to start prioritizing your mental health? Casey: “Since diving into that passion and purpose of prioritizing my mental health, I found that my overall well-being has drastically improved. I’m able to show up more for myself and those around me, and it’s been quite the journey that I am looking forward to continuing.” Have you experienced times when your mental health affected your physical fitness? Casey: “Those who know me know that I’ve struggled for a long time with anxiety, depression, overthinking, and [feeling] overwhelmed. I think that’s part of the human condition, and it makes me feel more human. When I share that on social media and with the iFIT Community, I’ve gotten an overwhelming response of positivity.” How do you manage those feelings when they arise? Casey: “As soon as I realize I’m not the only one going through it, I try to think about how [I’m] feeling in that moment and being okay with that. It’s a fitness journey, right? We’re trying to build our bodies and get healthier. But it’s also a journey of the mind to figure out who you are and build on that.” One last question. Do you have advice for people who want to create a healthy balance between fitness and well-being? Casey: “Just like building your body, think of your mental health as a journey. You’re not going to flip a switch and have everything figured out, just like you’re not going to do one bicep curl and have Arnold [Schwarzenegger] arms. It’s a process, and practice makes progress. Also, be kind to yourself. It’s going to take time. You will have setbacks, but that’s the part of the journey. We’re here together. We’re experiencing life together, so have grace with yourself. You’ll get exactly where you need to be as long as you keep showing up and doing your best.” Conquer your goals with Casey! Like Casey says, “Consistency and dedication are the only ways to approach a task—and conquer it.” Join these iFIT Series with Casey and give your mental health the attention it deserves.
