Each of the 5 main muscles has a "keeping it simple" section (hopefully a good starting point for anyone without previous knowledge) and an "in detail" page with comprehensive anatomical descriptions.
Use all the pages. Look at all the illustrations.
Find these 5 (paired) muscles on your body with your hands. Think of the full extent of each of the muscles, of how they provide the central framework for your body.
Try to activate each muscle, picturing them in your mind. Building this connection between body and brain is an an on-going process - something that you need to work at.
By starting from Base-Line you can begin to feel your alignment and improve your posture.
Please contact me if you have any comments or suggestions on how to make the anatomy pages as easy to understand as possible (or if there's anything else you'd like to comment on).
