"I'm Julia Karlstad and I'm an extremely dedicated and passionate fitness enthusiast and entrepreneur. I've owned and operated JKFITNESS, a health and fitness business in San Antonio, Texas for the past decade plus and been in the fitness industry for over 15 years, JKFITNESS is geared towards individualized personal training and overall wellness. 

When I met John Louis and was introduced to his machine, the FREEBOUNDER®, three years ago, I immediately fell in love with this powerful and versatile machine. The biggest attraction of the machine was the fact that it has zero impact on a person's joints. Despite no impact, it can rapidly get the heart rate elevated and challenge your muscles like no other piece of fitness equipment in the industry. I've had clients ranging from 8 years old up to 82 years old on the FREEBOUNDER®. I've also had athletes and other clients with many joint or medical conditions on the machine. This is a must have if you want to bring a whole new level of training to your facility."

I absolutely appreciate this apparatus, and wholeheartedly endorse it.

About me; I am 67 yrs old. I contracted polio when I was ten months old. It caused significant atrophy in my left leg. Most exercise apparatuses I tried were designed to build strength or are designed for able-bodied people. As a polio survivor, I found it awkward and difficult to use most gym/fitness center leg machines.

I have had the opportunity to use the FREEBOUNDER® for the past several months. The FREEBOUNDER® gives me the opportunity to exercise my legs, hips, and torso, in ways that I allow me to get an aerobic  workout and still have the security of multiple hand hold positions to stabilize myself. The FREEBOUNDER® provides me with a useful workout without any harsh impact on my joints. I have found the FREEBOUNDER® to be useful for a virtually infinite variety of exercises, and with slight variations it is possible to isolate different areas of muscles.

Over the course of the past several months I have progressed from 10 to 15 to 20 to 30 minute workouts. I use the FREEBOUNDER® six days a week in the morning before my shower, and then on to work. I have regained some muscle tone in my legs, lost some weight, and I continue to appreciate benefits after every workout.

I would recommend the FREEBOUNDER® to anyone who needs to exercise impact free or needs to work on recovery after injury or surgery."
