Propulsion

Intelligent training.

Propulsion owner Ashtyn Johnson learned her love for movement early – as a 3200 meter runner on the track, she also competed in shot put and was 3rd in state in power lifting in high school. Not the typical combination of activities for most athletes, but as she began to focus solely on running, she found injury stopped her from consistent training and kept her from competing at the level she knew

she was capable of competing at. Using a combination of running, cycling, lifting, climbing, ballet (yes, a power lifting climbing ballerina runner), and more she has had success competing at a variety of distances and disciplines and uses the same philosophy she uses for herself as she works with others.

A big part of being a good coach is staying a student.

I recently completed a mobility certification focused on improving range of motion, building strength within that range, and understanding muscle recruitment on a deeper level.

Mobility work is not just about “stretching more.” It is about creating strength and control in positions your body struggles to access — whether that is overhead mobility, t-spine rotation, or deeper squat positioning.

My goal is to help a wide range of people move better, train smarter, and stay active longer. And I will always keep learning new techniques to better help each individual I work with.

Show up for the miles when you feel good, and the miles when you don’t.
Not every run feels great. Not every split goes to plan. You keep running anyway.
That’s how progress happens.

Training outside hits different—and not just because of the view.

Fresh air, natural light, and open space can boost your energy, improve your mood, and help you stay more consistent. You’re not stuck in the same four walls—you’re moving, breathing, and pushing yourself in a more dynamic environment.

Outdoor training also challenges your body in new ways. Uneven surfaces, weather, and space force you to engage more muscles, improve balance, and build real-world strength.

Plus, let’s be honest—it just feels better.
Less pressure. More freedom. More focus.
If you’ve been feeling stuck in your routine, take it outside and see what changes.

Seven years ago Susanne signed up as a birthday gift to herself. Seven years later, she's still here — stronger, more confident, and feeling at home in her body. That's the whole goal. 🤍 Message me if you're ready to start your own journey.

This isn’t just a workout—it’s a lifestyle. At Propulsion Fit, it’s about building strength, confidence, and a community that pushes you to be better every day. Whether you’re just starting or leveling up, you’re not doing this alone.

Happy May 1st!

January 1st isn’t the only day you get to decide to change your life.
Wherever you are right now—start there. It’s not too late, and it never will be.

No shortcuts. Just consistency.

Every rep, every drop of sweat, every day you show up — it all adds up. Progress isn’t always loud or visible, but it’s happening.

Stay committed when it’s hard. Stay disciplined when motivation fades. That’s where real change begins.

Your body can handle more than you think.
It’s your mindset you have to train.
