" The X-iser Machines have been outstanding for the New York Jets.

We placed our five portable steppers in our training facility - two in the actual training room and three in the rehab area in the weight room.

The machines are a great exercise tool for warming up, therapeutic exercise, rehabilitation and aerobic activity. The machines have been received well by our athletes.

At the New York Jets, any non-practicing injured athlete works out on the field with the trainers and strength coaches. In the past these players just rode stationary bikes.

 With the help of The X-iser Machine, we have added a new closed-chain exercise on the field. I believe this machine will enhance our athletes' conditioning and also play an important part in rehabilitation, reconditioning and maintenance conditioning.

At present we plan to travel with two machines, using them in the locker room and on the field for
warming up. "

David Price - Head Athletic Trainer, New York Jets.

" In all honesty, I was a bit skeptical about The X-iser Machine. After your demonstration and our discussion of the many options The X-iser Machine presents, I knew it could be used as an adjunct to the Philadelphia Eagles' rehabilitation program.

With the wide variety of injuries we encounter, the use of The X-iser Machine can play an important role in rehabilitation. I have received positive feedback from the athletes and they want to make it a part of their routine workout.

The instructions you gave were excellent and especially good for athletes who must use the lumbar stabilization techniques. I recommend the use of The X-iser Machine in anyone's rehabilitation program and will definitely implement it into the Philadelphia Eagles rehabilitation program."

James T. Collins - Head Athletic Trainer, Philadelphia Eagles


" I've been using The X-iser Machine for the past four years at my office, and it has become a regular part of the physical training programs I design.

My clients of all ages routinely begin and finish their work sessions with the short "triple blast" program. Most people find it quick and easy but very challenging and effective.

And, at a fraction of the cost and size of the big treadmills and stationary bikes, many choose to buy their own X-iser Machine for home use. "

Rob Mottram, PT, ATC

Tilteist Performance Institute Advisor

" I use burst training with every client I have. It is not an option! Everyone gets on the
X-iser day one to experience what a real burst feels like! The X-iser is an essential part of my celebrity business - Nutrition on Location - and the foundation of my personal training routine as well! "

"To be honest, when I first saw The X-iser Machine I thought it was a toy. But after learning how to use it, I was simply amazed. As a world class speed skater, I have always taken pride in the power and strength of my quads.

After only one minute on this tiny machine I thought my legs were going to explode.

The X-iser Machine is an excellent tool for the conditioning circuits of skaters, hockey players, skiers and other athletes.

The X-iser Machine is portable and effective. Combined with the X-iser fitness programming and form technique, it makes an excellent tool for building speed, power and muscular endurance, and for developing balance, torso control, and proprioception."

" I have been using The X-iser Machine for about six months now and all I can say is "Wow!"  Why didn't I have one of these 17 years ago when I first started my career as a Personal Trainer?

I have seen previously unmotivated, uninterested clients suddenly become excited and dedicated - becoming fit and happy in the process. They love it because it's fun, it's different and it's time-efficient.

I love it because it's safe, effective and challenging. Thank you for bringing The X-iser Machine to the fitness world! "

" The era of having to work out for 30 minutes a day has come to an end.

The science behind The X-iser Machine and its effectiveness in creating VO2max, lactic acid buildup and growth hormone release is incredible.

Our clients, working out four minutes a day four times per week, have increased muscle mass by 20-30% and decreased fat mass between 10-30% in a three-month period on average.

Not only has it changed fat/muscle ratios, but it has also aided in dropping excess blood glucose issues. Any person can do it. We have patients from 110 lbs - 400 lbs.

We run a year long weight loss and lifestyle change program through nutrition, exercise and individual metabolic testing - there is no other workout program we will use. "

" The X-iser is revolutionary; it has changed my life and my practice. I used to work out eight hours a week and could never drop my body fat to where I wanted it. Much to my amazement, working just minutes a week with the X-iser instead has given me a significant decrease in body fat - from 30% to 24%. My clients have been thrilled with the X-iser as well. Nothing speaks like results! "

" I learned about The X-iser Machine at the bottom of the page for PowerBlocks. I had been heavily researching home gym equipment that was powerful and didn't take up much room since I don't have a space for large equipment in my home.

The pull for me was the PowerBlock name/quality, the research and the testimonials, which lured me in to do more study of your product.

Honestly, the photos of a mini-stepper would have thrown me off without reading further simply due to the images of cheap infomercial manipulative ads we are bombarded with. When I saw your product in Perform Better catalogs, on Paul Chek's site and on the TPI Web site, I was sold on my belief. When I bought one and tried it for myself, I was sold for life.

My favorite exercise so far is rebounding a five pound medicine ball while stepping and throwing/catching from hand to hand. (Next to short-burst stepping with hammer-curl, overhead press of course...!)
Thanks for a great product and I'll be working on a testimonial from our Center. "

Kyle Carso LMT, NSCA-CPT, Owner, Massage-Energy, LLC

" Anyone who tells you that four minutes a day to fitness is too good to be true doesn't know what they're talking about.

Once The X-iser Machine was explained to me, I had to try it myself. Throw away the late-night infomercial crap that's been sitting in the closet all these years.

Get rid of excuses about not being able to get in the gym. The X-iser Machine was the antidote to my couch-potato exercise ethic, and The X-iser Machine is here, I believe, to save obese America. Would you give less than 20 minutes a week to regain health? "

Dixon Wiles - The New You Show on 105.3 Free FM - Dallas, Texas

" I have gained tremendous strength in my legs from the use of The X-iser Machine.

In just a couple of months my belt size has decreased from size 34 to size 32, and my consistency and endurance on the course have improved from being in better shape.

My scoring average has increased by three shots. My lessons have been more successful because my clients have adopted the same X-iser Machine routine.

The biggest problem with my senior membership is their inability to make a turn. This has now been dramatically improved with The Golf Tee Warm-up, the benefits of which are incalculable. Instead of spending half the lesson working on their turn, we immediately start working on their fundamentals. Thank you for the best-designed game improvement aids in the world. "

David Smolsky II - Head PGA Professional, Wildwood Golf & Country Club, Cape May Court House, NJ

" As one of the top-producing trainers for an international fitness chain, I went out on my own. Now, working once again after a personal heart valve repair, I specialize in training for martial artists, lifestyle/weight management, seniors/masters, and cardiac post-rehab. I would not be without the X-iser and PowerBlocks. I use them myself and recommend them to all of my clients "

James Elliott Clayton

"With over 15 years of experience in the fitness industry, I was at first extremely skeptical about The X-iser Machine. It appeared to be too small to match the performance claims.

However, after experiencing the machine firsthand, I can attest that it is truly remarkable. This portable machine is superb for basic aerobic stepping, circuit training, interval training, and dynamic group exercise classes. Consequently, the X-iser Machine is an excellent product for retail and commercial customers."
