I have used this book many times in the short time I have had it.  I have used it  when I am coaching my swim team and have also found it very helpful for myself  for workouts in my own training as a swimmer and a triathlete

This is a great workout book.  There are a large number of workouts, broken down into different areas (distance free, middle distance, sprint, IM).  Everything is clearly explained, so there is no guess work.  The workouts are long, ranging from about 3500yds to over 5000, but they can easily be scaled back but removing a set.  I highly recommend this book, especially if you are without a coach.

Lots of good workouts, easy to mix and match.   Makes doing your workout a lot more interesting, since it makes changing your routine easy.   Book holds up well around water, so you can bring it to the pool deck for easy reference.

I've been getting back into the swim of things lately.  I was wanting a guide to provide some solid workouts to help keep me motivated and on task.  This is a great tool, however the scheduled workouts are for the SERIOUS swimmer.  Taken at face-value, minimum distance workouts are AT LEAST 3,000 yds/mtrs with most distances averaging in the high 3,000s or low 4,000's.  While you can modify the workouts to match your allotted time, doing math during the middle of a workout is more headache than it is worth.

Product is durable and great for use at the pool, water resistant.  I recommend for longer swims when you have AT LEAST an hour to 1.5 hours to devote to one of the prescribed workouts.
