I mean no disrespect to the fitness industry here, or those who work in it (I have been working in the industry for nearly 20 years). But I do think the industry has played a role in creating some false beliefs about what movement is and we have allowed those beliefs to rob us of the simplicity of incorporating more movement into our daily life.
Instructors and classes can be instrumental in helping us to break bad habits, build effective programming for specific goals, or to reach goals more efficiently, but “exercise” is not the end-all-be-all to movement.
You don’t need a gym. You don’t need an instructor. You don’t need a fancy pair of shoes or a yoga mat to MOVE your body. You don’t need a laundry list of principals to abide by and you certainly don’t need permission from anyone other than yourself.
