I love my Katalyst. I've used the device for over a year now and it has become an essential part of my exercise routine. The strength training works but best of all it has provided so much help to my bad shoulder and knee (old sports injuries). I can overhead press again without pain for the first time in almost a decade.

I purchased the Katalyst initially to try to rehab my shoulder, hoping to avoid another rotator cuff surgery (and I know what a tear feels like and I was dreading another surgery). Amazingly, after only a couple shoulder workouts, the constant pounding pain was gone, within a month I realized I was reaching for things above my head that I would’ve winced at a month earlier. Since then, I’ve stopped all free weight workout (after 40 years), muscles are stronger and the joints don’t ache. My wife and numerous friends have since purchased the Katalyst and all are pleasantly surprised by the workouts. In addition, the customer support has been fantastic.

Love the suit and the programs. Have been using now for 6 months and have seen real gains in muscle mass and loss of fat. Katalyst quickly replaced my suit when I dropped a size!

I’m honestly trying not to use hyperbole, but I LOVE my Katalyst suit. It gives me everything I love about using weights (muscle gain, increased metabolism) without the stuff I hate (worrying about my form, stress on back and joints.) Worth every penny.

The Katalyst Suit and programs are a very effective way to optimize your workout time
By Martin W.
I love working out with my Katalyst. The results are awesome. I challenge myself every week and love the feeling of setting a new record in one of the categories- strength, power , cardio. And the stretching and recovery programs are a great way to wrap up the workouts. I recommend this to anyone who loves seeing results without injuring your body. I have back issues- like most people- and I trust this system to keep me from hurting myself. Lastly, they keep coming out with new workout programs. There’s a lot to choose from.

I have used the suit consistently over the past four months, which has led to a gradual increase in my core and lower back strength. During this same time frame, I have noticed a decrease in the recurrence and severity of low back spasms. I look forward to continuing this positive trajectory, in which the suit is playing a prominent role.
