“Been working out since 1975. The Isomax has taken center stage. The combination of convenient, very effective isometrics and seeing the amount of force generated on each rep is phenomenal. Dragon Door's innovations are a godsend. I'm 70 and the strongest I have ever been.”

“I have been able to gain more muscle mass and increased strength with the Isomax than with any free weights or weight machine. I am in my mid 40s and have been lifting weights since my late teenage years, but nothing I have tried compares to the Isomax!”

The book is excellent!!

I originally had it years ago, but lost it when I walked headlong into my own stupidity. Thanks for showing me the opportunity to purchase another copy.
Great price!! I completely forgot it is still out there. Now that I've retired and am slowing down. I believe it will be a great read.

This is an amazing book

This is an amazing book. I am amazed by the power of the isometrics and have seen great transformation in my body in just a month. Happy to have found this information and I highly recommend it

Excellent book

Excellent book, with some crazy rings based exercises; I just wish there was some kind of program for progression.

Good Overall, but takes from other Dragon Door books

While this is a good book for a beginner, both the bodyweight and kettlebell exercises can be learned in greater detail in other Dragon Door books (Convict Conditioning covers the exact same six calisthenics movements and Pavel covers the same kettlebell exercises). I probably would have found better value if I was a first time reader solely focused on fight conditioning.

Excellent
