Are you interested in a career in Personal Training and Sports Performance - but wonder how you’ll ever be able to actually build a secure, sustainable career around doing what you love?

The Fitness Industry is Saturated with Trainers Who Are:

  • Tired and burnt out from a soul-sucking environment and an unsustainable, draining schedule

  • Worried they’ll never be able to afford to take the next step in life

  • Don’t have Proper Guidance, Structure, and Continued Education To Support Their Professional Growth 

  • Never Feel That They Are Making A Difference Or Genuine Connection With Clients Because Most Gyms Are A Revolving Door Of Members and Staff

  • Feeling isolated that they have to go it alone and don’t have a solid supportive team around them

Many Trainers Have Also Experienced:

  • Leadership and management that don’t deliver proper guidance, structure, and continued education to support their professional growth

  • Being part of a company that is in neutral that doesn’t display an exciting future of continuous upward mobility, security, or career sustainability

  • Drama-filled, toxic work environments where you have to constantly cover for underperforming team members

Our Vision at PowerStrength Training Systems is Simple.

We Create Extraordinary Careers for Trainers by Focusing on these 5 Key Areas:

  • realistic schedules that are actually sustainable 

  • competitive, guaranteed compensation & benefit packages with continuous growth options and incentive opportunities

  • a growth-minded, professional team environment that makes you proud to say what company you’re a part of and who you work with

  • a platform to have real connections, relationships, and impact that helps change the lives of our clients through one of the best training experiences on Earth

  • a value-driven company that operates with integrity to always do what’s best for the team members, clients, and local community

The PowerStrength Difference:

Who We Are

Here is What Your Role Could Look Like:

Building Impact: You will be part of a team that impacts thousands of lives in our local community every year. This is achieved through conducting small, personal sessions with real people where your work has a direct, impactful effect.

Coaching: You will coach about 15-30 Hours per week and be able to make a serious impact in the lives of our clients every single day and be known as a local expert.

Community Building: Our goal is to make fitness as FUN as possible for our clients and make it easy for them to show up to their sessions. Your job goes far past the sets, reps, & “X’s & O’s” of training. From the second your members walk through the door, they will be welcomed into the community and cared for & served to the highest standard.

Member Experience and Results: All of our trainers are not responsible for sales or getting new clients. But they are responsible for creating a first-class experience that delivers guaranteed results for every member under our roof.

Job Requirements

Action Taker: You need to be the type of person who is proactive and gets joy out of getting things done.

Willing to learn & execute: We utilize various technologies and softwares to enhance every role and keep our focus on what matters most in our service delivery.  An understanding of social media, email, and other computer-based tasks will be necessary.

Enjoy talking to people: You don’t have to be crazy extroverted or the life of the party, but you must enjoy talking with people and giving/getting direction.

You need to be a person who loves to deliver remarkable experiences to other people…aka, you need to be someone who feels good by making other people feel good.

Detail oriented: You need to nail down the details. You don’t need to race through work and deliver mediocre service. We need you to slow things down and get them done right. We want you to be meticulous in your work so our clients benefit on every level of service they receive from us.

What powerstrength clients have to say

“I LOVE PSTS!  From my very first time stepping into the gym, I felt like I belonged.  All of the trainers and members are extremely welcoming and encouraging - it really does feel like a community.  The trainers meet you where you are at and there is no comparing or ‘one upping’ from other members.  Everyone is on their own journey and the coaches make sure to celebrate you where you are at.  The trainers do an extremely good job of tailoring your workout to your needs and abilities, while at the same time encouragingyou to go farther than you ever thought you could. From the constant high-fives, fists bumps, and shouts of encouragement, I feel like I can do anything that is asked of me!”

- Wendy T.  - PowerStrength Member

“.. I never in a million years thought I would enjoy going to a gym. But this isn't a gym. This is a community with no judgment. People just like me, working to improve themselves. The trainers are the best people ever. They are so kind, encouraging and supportive. They have become my friends. I will forever be grateful to the PowerStrength Team for making me believe in myself!” 

- Mimi V - PowerStrength Member

"Thank you so much to the staff at PowerStrength. Your investment in kids in West Michigan goes far beyond a typical gym. There’s a reason people will travel up to an hour+ away to train with you. The leadership, character development and genuine care for each person that walks through the door is unparalleled. To our family personally, it was a sanctuary for our son.”

- Mother of a PowerStrength Athlete

What industry leading experts Say about powerstrength

I am so inspired by the team at PowerStrength. First off, the facilities are world-class and the results from all of their innovative programming are unparalleled in the industry. But that is only one reason why PowerStrength is different. The other is that their trainers are operating on a different level and they really care. Each team member pushes themselves to lead by example, continue pushing the limits of their own personal development, and they execute every day on the values and the mission of the PowerSterength Family. Their results are only second to the amazing and connected community they have built over the last 12 years. Thank you for leading the way and setting an example for trainers in our industry!

“Mark and the PowerStrength Team are in a league of their own.  Over the last 12 years in the industry, I’ve seen the top gyms in the country up close and “behind the curtains”... and they don’t come close to the operation that PowerStrength has.PowerStrength is at the forefront of education & development. From top to bottom, they have developed a team of rockstars. I have made the 3.5hr trip on multiple occasions to bring my staff to learn and watch their training. I can’t speak highly enough of their product. If you have never seen it up close, you should! Their sessions are second-to-none and the environment they have is ELECTRIC!They have taken over West Michigan and, and in my opinion, are just scratching the surface. In a world of fake clout & pretenders, they are the real deal.” 


Connor Flahive

Owner of Flahive’s Strength Training and Flexx Personal Training, Chicago, IL

“In an industry filled with empty promises, “snake-oil salesmen”, and self-proclaimed social media gurus - the PowerStrength Team and facilities are a breath of fresh air. This is a group of professionals who hold each other accountable to always improve professionally, and to always over-deliver. The secret sauce may well be outstanding leadership in PowerStrength Founder and Owner, Mark Ehnis, who refuses to be second-class in the industry in any category. If you want to be great, PowerStrength is the ultimate destination to turn your passion into a sustainable and fulfilling career.”
