In the UK the most common entry point is to start with a Level 3 Mat Pilates qualification, which offers a standardised entry into teaching Pilates.
This certification will get you well-acquainted with the core principles of Pilates, anatomy, the basic mat Pilates exercises and how to teach. 

Unlike Mat Pilates, there is no set of national professional standards for Reformer training and it is unlikely that there will be any time soon. 
Therefore any employer will usually request a Level 3 Mat Pilates certification plus they will expect that you have experience and further training on the reformer bed.

Studio 281 has therefore created a contemporary reformer instructor training programme, that is only available to those with a Level 3 Mat Pilates qualification.
This requirement is to ensure that instructors are teaching reformer classes safely and with sufficient training.

As studio-owners and instructors ourselves, we know what skills matter most and what is required to become an excellent Reformer Pilates Instructor. We made sure that our Reformer Instructor training course fills the gap between Mat Pilates and a Reformer trainer, offering innovative contemporary training as an addition to the essential Pilates training that stays true to the method.

Generally, insurers will require that you’ve trained to the national standards required for your modality. But remember, for Reformer, there are no national standards yet, so in this case most companies will cover you once you’ve been signed off as competent to teach with a Level 3 Mat Pilates Diploma and relevant experience and training on a reformer bed. We ensure all our students leave their program with this experience via practical teaching, observation and participation hours, as well as personal feedback and thorough assessments.
