When I bought the book by fellow blogger and authors Reeves, Paglini, et al. Triathletes Swim First: 100+ Beginning Swim Workouts for Triathletes, I had planned at first to buy a hard copy.
I changed my mind and downloaded the e-book instead. The reason: I use the book by these athletes for one of many options to train the core muscles, and for mobility training of all muscle groups with cardio, breathing, recovery, and buoyancy benefits included.
Takeway Training Tip: With the book on my desktop, I can print-off one of the workouts from one or more pages, and bring it with me to the pool for guidance.
This is also true for all of those fitness, training, and health books that tend to get lost on your bookshelves with workouts, pictorial how-to sequences, and instructive tips in them. If you buy them in e-book form, you can easily print-off the pages with the content you want to work on, and take them with you.
You can even laminate them, create a card folio, and re-use them to save paper, and increase your fluency in variety training.
This is very much a simple way to put all of those sport, training, and fitness books to good use in your adaptive training life.
It also helps the athlete or wellness author to sell an e-book instead of a hard copy, as there is less production expense. Here, the green of the trees and the green of author profits come together.
