Older Yet Faster (book with illustrations and photos, and online lesson and exercise videos) is a manual for teaching runners how to transition to efficient running and to help them to avoid incurring almost all of the common running injuries as they do so. It is ideal for beginners to learn how to run well and for experienced runners to changeover to good technique. Coaches can also use this book as a reference on how to implement technique change for their clients, and we expect it to become the go-to manual for medical professionals, to help them deal with running related injuries caused by bad technique and footwear.

After learning how injuries are caused and then gaining a good understanding of running technique in the early chapters you will be prepared to read about our technique-change system which we call "OYF Running". Heidi's Strengthening Exercises consists of a well-ordered series of exercises which will help your body safely adjust to the redistribution of the workload and are essential to rebuild parts of the body which have been neglected due to poor technique.

We identify specific injuries and how they are caused and we show how by improving running technique, and re-strengthening these injuries are quickly cured. Podiatrists will find Heidi's experiences and advice particularly interesting, especially as they will almost certainly, be in conflict with what is still taught in universities.

In Appendix A, Keith discusses how to implement his Lessons from a coach's point of view, in Appendix B, Heidi explains how she treats her patients who are suffering with specific injuries and in Appendix C she explains her Strengthening program in greater detail for medical professionals and interested runners.
