What Real Users of The IsoMax Have to Say

“Having been a Strength and Conditioning Coach for 40 years (33 years at the college level, 7 years at the high school level), I have seen a LOT of devices come and go. The IsoMax impresses me so much that I would definitely incorporate it into my program if I were starting all over again in my career. It'll defin… Read More

“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.”

Bob Lorenz

“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!”

It was a good live review of the pushup chapter from the book

It was a good live review of the pushup chapter from the book. But it unintentionally (I think,) accented the importance of using a slow with the exercise. Gong down on a two second pace, pausing one second at the bottom, and then rising on a two count, ads tremendous value to the exercise. When I did the book course originally, I topped out before getting to the one handed push up. I suspect that, given recent gains, that should be able the master the one armed push up this time around while using this cadence.
