The BASI Pilates® Block System, created by Rael Isacowitz of BASI, is a smart way to organize Pilates exercises. It's like a filing system that sorts exercises in a logical order, making it easier for instructors to plan classes. This system allows for classes to be both well-structured and flexible, meaning they can be adjusted to fit the needs and abilities of each person attending.

The beauty of this system is that it ensures classes are balanced and comprehensive, touching on all types of movements and engaging different muscle groups. This means everyone gets a workout that's just right for them.

As instructors get more familiar with the system, they become better at using it to craft classes that are both challenging and accommodating for everyone. Essentially, the BASI Pilates® Block System helps instructors deliver high-quality, personalized Pilates sessions, making it a valuable tool in the world of Pilates.
