Most treadmills are built for mechanics. IRENA, PENT Fitness Equipment, was crafted for mastery.

With its self-powered curved design, IRENA responds to your stride in real time, creating a natural, fluid running experience that eliminates the need for electricity. Every step feels lighter, faster, and more intentional—powered only by the runner. Framed in hardwood and finished with marine-grade stainless steel and natural leather accents, IRENA transforms a piece of cardio equipment into an architectural statement.

Handcrafted by European artisans, the IRENA Curve Treadmill is engineered with precision for athletes who value both performance and design. Its form encourages efficient biomechanics, reducing impact while enhancing endurance training, all while offering the tactile warmth of natural materials. More than equipment, it is an expression of strength, elegance, and self-propelled power.

For those who believe their fitness environment should inspire as much as it performs, IRENA delivers the rare harmony of innovation and artistry.
