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.”

“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!”

Excellent Isometric Trainer. Additional training technique to weights. Exercises your muscles differently than normal weights. For those people like me who have never trained isometrically they stimulate your muscles without risk of injury. Isometrics strengthens muscle strength / endurance in different ways to w… Read More

I love my IsoMax. I am 55, I had the normal aches and pains you would expect for someone my age. Back, knee and tricep tendonitis. I have been using the IsoMax for 4 months, my aches and pains have faded to nothing. My blood pressure has also improved and i have effortlessly gained muscle. And i am only using it … Read More

Best Kettlebell on the Market

The feel and weight distribution of this kettlebell is the best on the market.

Love RKC kettlebell

I'm not sure if I got a one off but the new finish is inferior to my older RKC Kettlebells. The others have a nice matte finish where my newest one has a shiny finish and looks like a cheaper version. Still a good bell, well balanced and probably still better than most. Got a 7/10 for that reason. By the way, I'm not a weekend warrior, I'm in the fitness industry: trainer for 15 years. I may know something.

A product I love to snatch

I'm happy that I've found Dragon Door kettlebells.But it took a fair amount of searching.Started with trips to a local sports/fitness rquipent store, then Target.Nothing at all looked convincing.My first kettlebells were bought yers ago locally and are made with epoxy coating.That's just plain wrong. How could someone come up with such an idea? It hardly makes any sense from a ruggedness/longevity of the product prospective.But that's what was available at the time.This time I put in more effort into my research.And I would like to thank the person who wrote a very thorough review of the best kettlebells out there.I decided to go with simply the best!

Repeat customer

I keep coming back for more and can't imagine buying kettlebells anywhere else!

Unmatched quality

I have used many different brands of kettlebells and will only buy RKC. I have a pair of the 24s that are used almost everyday, they will humble you and empower you. Handles are the perfect size and are breaking in nicely. Another great product from RKC.
