Your fitness industry experts. Products and experience for athletes, by athletes.

What do we do?

At Strez Fitness Solutions we design and equip unique training spaces.

Gyms, clubs, studios, corporate gyms, home gyms, regardless of size, cannot be forgotten.

We design equipment personalized to your training needs and the unique character of your brand. We carry out custom projects, in a Polish factory, supporting the Polish economy.

We design and produce training solutions that we, as enthusiasts and athletes, test in our own clubs.

We were born out of need and passion. In our opinion, this is the only right way to support our clients in developing their coaching businesses with great pleasure for years as designers, equipment suppliers and consultants.

Who designs and delivers solutions?

Our solutions are the result of the work of a team with many years of experience in the fitness industry. As trainers, designers, club owners and manufacturers, we understand every aspect of the functionality of space. For each project, we select the right team to take care of every detail - from concept to implementation.

How do we work?

Like our equipment, our approach is always personalized. Every training space has its potential, and we maximize it with modern solutions tailored to the specifics of the place and the client's vision. We analyze, advise and deliver ready-made solutions that leave the client with a ready-made space to train. We are at every stage of the project implementation.

Does the client have any influence on the design?

Each project is fully personalized. We work with the client at every stage to create a space that reflects their vision and needs. Strez offers full flexibility in terms of equipment and design, ensuring that the final effect is not only functional but also unique. Tailored to the client's brand.

I know the fitness industry inside and out. I’ve spent years analyzing clients for whom training is an essential part of their lives. I’ve been training since I could walk. I know the struggles that clients, trainers, and club owners face.

At Strez I support clients in the areas of business model and marketing strategy.

The challenges that owners most often come to me with are:

  • How to create an offer for my club?
  • What marketing activities should you undertake with a limited budget?
  • How to acquire new and retain regular club members?
  • How to work less in your own business?
