Who is the The Core poster for?
The Core belongs to the Body & health section rather than to a school year, because health is not something one grade owns. Anyone learning movement can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the The Core poster?
The core's job is mostly to resist movement, not to produce it. A wall chart earns its place by being glanceable from where the work is happening, so The Core belongs on the wall where that health work actually happens, within glancing distance, rather than filed away.
What other posters go with The Core?
Breathing Under Load, Common Injuries and The Hip Hinge sit alongside The Core in the Body & health section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Breathing Under LoadCommon InjuriesThe Hip Hinge
Is the The Core poster free to download and print?
Yes. The Core downloads as a free PDF with no account, no email and no watermark, like everything else in the Body & health section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the The Core poster print at?
The Core is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of The Core loses nothing.Printing guide
