I'm a masters swimmer and I've had this book for nearly a year, and I find it a valuable resource.
There are lots of different ideas so you can keep trying new things and altering your workouts, which is great for reducing tedium in the gym.
It seems to be one of those books that people with varying starting points about land work for swimmers can get some ideas from. You can read as much or as little about the science behind it as you want.
There are a mix of exercises: medicine ball work, swiss ball work, stretch cords, ciruits, free weights and resistance machines.
The photos make some of the more complex exercises better to visualise.
As I mentioned I've been using ideas from the book for nearly a year and I have noticed the difference both in the gym and in the pool; I just wish I'd found it sooner!
