A major feature of my tutorials is that I actively update them as new science and information becomes available. Unlike regular books, and even ebooks — which can be obsolete by the time they are published, and can go years between editions — this tutorial is updated at least once every three months and often much more. I also log updates, making it easy for readers to see what’s changed. This tutorial has gotten 15 major and minor updates worth logging since I started logging carefully in late 2009, and countless more minor tweaks and touch-ups.
Minor update (Oct 23 '13, section #2.4) — Added a couple paragraphs about exactly where in a muscle strains tend to occur, and why. See section #2.4, Location, location, location.
Major update (Jul 3 '13, section #3.4) — Much more detailed and evidence-based tips for estimating recovery time. See section #3.4, Good tricks for knowing when it’s safe to use a torn muscle again.
Minor update (Mar 29 '13, section #4.1) — Upgraded risk and safety information about Voltaren Gel. See section #4.1, You and “vitamin I”: anti-inflammatory meds, especially Voltaren® Gel.
Product upgrade (Jul 30 '12) — PDF versions of all SaveYourself.ca tutorials are now available. They are ideal for printing and offline reading on e-readers. The online version will always be the “real” version (guaranteed current) and the best way to read the books, but fresh PDF copies will always be available to customers. Announcement on my blog: Finally! PDF versions of my books, and the “technologically interesting” story of how they were made.
New section (Mar 30 '12, section #4.17) — No notes. Just a new section. See section #4.17, Prevention: will water and electrolytes make a difference?
Update (Nov 2 '11, section #4.9) — Rewritten and expanded with important evidence about how stretching does not prevent strain injuries. See section #4.9, What about stretching? Can it treat or prevent strains?
Minor update (Jul 14 '11, section #2.2) — Added a (very) funny clip from the TV show Glee. See section #2.2, True muscle strain checklist.
Major update (Jun 21 '11) — Major improvements to the table of contents, and the display of information about updates like this one. Sections now have numbers for easier reference and bookmarking. The structure of the document has really be cleaned up in general, paving the way for efficient conversion to other formats (Kindle, Apple’s iBookstore, etc). Best of all, it is now significantly easier for me to update the tutorial — which will translate into more good content for readers. Care for more detail? Really? Here’s the full announcement.
New artwork (Jun 8 '11, section #3.3) — Added a nice new diagram of strain severity. See section #3.3, What’s the worst case scenario for your muscle strain?

New section (Oct 5 '10, section #4.13) — Another new section and yet more good new evidence about prevention. See section #4.13, Prevention: Warmups work.
New section (Sep 15 '10, section #4.16) — New section based on solid new evidence about prevention. See section #4.16, Prevention: can you prevent muscle strains by upgrading your muscle balance?
