Felix Grewe and Mike Diehl have put together a book that includes many ways to build a circuit training plan and adapt it as your training changes or you become more fit.

Fit Strong Lean: Build Your Best Circuit Training Plan includes helpful photos and a variety of exercises for those of us who want to do our circuits at home or in front of a mirror at the gym, but not with a paid trainer.  This book provides top notch, professional assistance at a fraction of the cost.

In this episode, we learn a bit more about what each of them has to offer us to "build your best circuit training plan".

Mike Diehl is a certified fitness coach for sports performance as well as health, fitness and sports rehabilitation. He has worked for the German Women's National Tennis Cup Team for more than 10 years as their fitness coach and has worked with Wimbledon Champions as well as top soccer and ice hockey teams in Germany.

Mike likes to start his day early with an intensive workout. His philosophy is: "Everybody is able to become fitter, stronger and leaner! Pain doesn't stand a chance against passion. It's all about finding a goal for which you are willing to accept pain and hard work."

Felix Grewe is a professional journalist, author, and fitness and tennis aficionado. He worked for many years as a full-time reporter for a German tennis magazine and went on to head up the media department of the German Tennis Federation. He now works as a freelance journalist, author and social media manager. 

Felix and Mike met for the first time about 7 years ago when Felix tried an experiment with Mike for a tennis magazine article. This was the spark for bringing together a workout book of Mike's exercises and philosophy. Felix, as the writer/journalist and both as tennis and fitness experts put Mike's methods into words. And, of course, Felix trains regularly using Mike's workouts.
