The stretching industry has seen huge growth in the past 3 years, with many hundreds of studios popping up. As veterans in the field, our approach is time tested, experienced and 100% effective. Although this sounds like marketing speak, after 30 years of teaching stretching and publishing 8 books on the subject, we know what works, what doesn’t, and what’s unsafe. We also know that practitioner ability and interest vary, so we built and patented equipment to ensure you get a great stretch every time, no matter your instructors experience, skill level or interest. 



Stretching equipment has also been used for centuries because it is well known that when the body is gently supported, it releases. It’s called “positional release.” The StretchFit approach is to use modern equipment to target specific muscles and to facilitate maximum support and relaxation in each stretch. 



Anyone who has studied medical science knows that muscles are found in compartments, or bundles. A well known example is the hamstrings, a bundle of 4 muscles at the back of the thigh. Our approach is to isolate each of the bodies compartments and stretch them methodically, just as weight training equipment does.

It’s, anatomically based, precise, and no one is left guessing “am I doing it right!?” 

At StretchFit we also hold stretches for 2 to 3 minutes. Research shows that this is the minimum period of time for biological adaptation. 

StretchFit uses a method called PNF or contract/relax stretching. Its use is common in physiotherapy and osteopathy.  Although it sounds complex, its simple to perform and vastly accelerates the acquisition of flexibility. 



Our teachers are the highest trained in the industry. There are five individual StretchFit training manuals and training is personally conducted by StretchFit creator Anthony Lett and Kenyi Diaz. They have released 8 books on stretching including 4 Amazon bestsellers and lectured internationally on stretching in 30 countries.
