The Fitness for Life interactive iBook works on iPads, so it’s best to use an iPad when searching for the book. Open the iBooks app, tap the Store button, and enter “fitness for life” in the search box. The first results should include the Fitness for Life interactive iBook (released July 15, 2014). Note that the results will include the updated fifth edition (released March 31, 2006), which is not interactive.
If you search the iBook store on a phone or other mobile device, the results might not include the interactive iBook because the product can’t be used on those devices.
You might be able to find the interactive iBook by searching iTunes on a laptop or desktop computer (or use this direct link: https://itunes.apple.com/us/book/fitness-for-life/id900072316?mt=11), but results may depend on whether you’re using a Mac or Windows system. Again, the best method is to search from your iPad, because that’s the device that will run the interactive iBook.
