If you’ve spent any time researching classical Pilates, you may have come across the name Gratz. At Sharp Pilates™, every piece of equipment in our studio is authentic classical Pilates apparatus – and that’s not an accident. Here’s what Gratz is, where it comes from, and why the quality of apparatus matters for your practice.


The Origins of Gratz Apparatus

Gratz Industries has been manufacturing Pilates equipment since the 1960s, when Joseph Pilates himself worked with the company to produce the apparatus used in his original New York studio. The designs are based directly on Joseph Pilates’ own specifications – the same proportions, the same spring tensions, the same craftsmanship he developed over decades of teaching.

When Joseph Pilates passed away in 1967, Romana Kryzanowska continued teaching the classical method using Gratz equipment. It became the standard for classical Pilates studios worldwide and remains so today.


What Makes Classical Apparatus Different

Not all Pilates equipment is created equal. The Pilates industry has expanded significantly over the past two decades, and with that expansion has come a wide range of equipment manufacturers producing reformers, cadillacs, chairs, and barrels at varying price points and with varying design philosophies.

Classical Pilates apparatus is different in several important ways:

Proportions and spring tension. Classical apparatus is built to the original specifications developed by Joseph Pilates. The spring tensions, carriage dimensions, and overall proportions are designed to work together as a system – each piece of apparatus complementing the others in a way that supports the classical sequence.

Craftsmanship and materials. Classical apparatus is built using high-quality materials and time-tested construction methods. The equipment is built to last – many studios around the world are still using apparatus that is decades old.

Integrity to the method. When you practice on classical apparatus, you are practicing on equipment the method was designed for. The exercises feel different – and work differently – on authentic apparatus than they do on modern alternatives.


The Apparatus at Sharp Pilates™

Sharp Pilates™ is equipped with a full complement of authentic classical Pilates apparatus from Gratz, Pilates Designs, and Legacy – the gold standard manufacturers in classical Pilates equipment. Our studio includes reformers, towers, cadillac, wunda chair, high chair, arm chair, spine corrector, foot corrector, ladder barrel, small barrel, pedi pole, and more. Each piece serves a specific purpose within the classical sequence, allowing our instructors to work with clients across the full range of classical Pilates exercises.

This matters for your practice because the apparatus isn’t just equipment – it’s a teaching tool. The springs provide resistance and feedback that guides your body into correct alignment and helps you develop the strength, control, and body awareness the method is designed to build.


Why We Only Use Classical Apparatus at Sharp Pilates™

The decision to use exclusively Gratz, Pilates Designs, and Legacy apparatus at Sharp Pilates™ is a reflection of our commitment to the classical method in its most authentic form. Romana’s Pilates is a lineage – a direct transmission of Joseph Pilates’ work through Romana Kryzanowska and her students. Using equipment built to classical specifications is part of honoring that lineage.

It also means that when you practice at Sharp Pilates™, you are experiencing Pilates the way it was meant to be experienced – on apparatus built to the original standards, taught by instructors trained in the classical tradition.
