With X3, you train with greater force to trigger Greater Gains

X3 Fitness System

The X3 Home Gym: Greater Force, Greater Gains

Why risk injury and waste time for minimal results? Weights overload joints, underload muscles, and limit capacity to your strength in the weak range. Your body is 7X stronger in the impact-ready positions, near full extension. That’s why X3 requires lighter forces in the weak range and very high forces in the strong range.

Why Is X3 More Powerful Than Weights?

You are cutting your gains short. Static weights overload the joints and underload the muscle.

Your body is 7 times stronger at full extension in the impact-ready positions than in the joint-compromised starting positions.

The X3 provides greatly varied resistance through each movement, enabling you to recruit more muscle, produce higher HGH levels, and drive Greater Gains.

  • More Resistance Where Your Body is Stronger
  • Less Risk of Injury Than Traditional Weights
  • Easier On the Joints, Harder on the Muscle
  • Complete Muscle Fatigue for Greater Gains

Maximize Muscle Fatigue and Growth

X3 is the strongest variable resistance training system on the market. Because your body is weaker in starting positions, lighter forces are required at the beginning of the movement, where weightlifting injuries often occur.

With X3, the weight increases as you move from the weak range (near the chest) to the strong range (near full extension), where you are capable of producing 7x more force.

This allows you to safely train with greater force than you would with weights, triggering greater muscular growth.

  • Up to 600 lbs of Available Force
  • Full-Body Muscle-Building Workouts
  • Build Strength Faster
  • Greater Gains In Just 10 Minutes a Day

All It Takes Is One Set

By providing heavier loads near full extension, the larger muscles groups become completely exhausted in one set. Follow the X3 Program and discover how strong you can be, in just 10 minutes a day.
  • Full Muscle Exhaustion in One Set
  • A Portable, All-In-One Home Gym System
  • Up to 30% More Resistance Than Other Bands
  • 30-Day Money-Back Guarantee

The Ultimate Solution for Maximizing Muscle and Minimizing Body Fat

The X3 resistance band bar delivers variable resistance that closely matches the curve of human force production, stimulating optimal hormonal release, fat loss, and muscle growth for a faster, more effective workout.

X3 Bar Results

X3 Bar: Before and After

  • John Ferro before and after using the X3 bar workout system

    John Ferro

    "I lost 22 pounds of body fat and gained 20 pounds of muscle in 30 weeks. I am so happy with my results. I will never go back to weights."
  • David Fish before and after using the X3 bar workout system

    David Fish

    "One year ago, I started using the X3 and I’ve been following the workout program. My midsection has always been a problem area and I am finally starting to get the results I want. I’ve done a lot of other programs with similar or even harder work, but never saw results like this."
  • Alex Naymark before and after using the X3 bar workout system

    Alex Naymark

    "Since I started X3 about 17 months ago, I’ve completely transformed my body by losing 35 lbs of fat and putting on 12 lbs of lean muscle. I’m still getting leaner while increasing muscle mass. This has been a life-saving workout regimen coming from an injury ridden powerlifting world. X3 is the best workout ever designed for putting on muscle. Thank you, X3 team!"
  • Stephen Heston before and after using the X3 bar workout system

    Stephen Heston

    "I started X3 at 185 lb and between 12-15% body fat. I am currently at 190 lb and between 7-9% body fat. What I found remarkable about the X3 is that I was able to add pounds of muscle mass while my body fat % saw a steady decrease. All while training MMA full time. When I was hitting the gym to lift weights, I never saw results like that. I use X3 right before I work a heavy bag, and it’s made a BIG difference in strength and performance."
  • Aaron Legassie before and after using the X3 bar workout system

    Aaron Legassie

    "I stopped training for over 10 years. I just lost the desire to weight train because of the lengthy sessions with minimal results. I’ve been utilizing X3 for 8 months now. It has changed my life. I’ve lost 117 POUNDS! The program, as-is, is absolutely amazing. I have gained an incredible amount of mass and can see definition in my abs for the first time."
  • Mabel Fornos before and after using the X3 bar workout system

    Mabel Fornos

    "I lost 30 pounds of fat in 4 months and gained muscle. My body has transformed. X3 is Amazing! THANK YOU!"
  • Caleb Demmons before and after using the X3 bar workout system

    Caleb Demmons

    "I started at about 190 pounds in March. Today I weighed in at 173. Being light but strong is exactly what I need and x3 has helped me skyrocket my results and training. As a professional parkour athlete, regular weightlifting always left me too sore. With X3, I can lift as heavy as possible and jump right into training afterward. I’m never sore and I perform better. X3 is the perfect supplement to my training."
  • John Cannon before and after using the X3 bar workout system

    John Cannon

    "I had consistent lower back and knee issues prior to X3. After using X3, I have had no injuries or ailments. My starting weight was 278 lbs and my current weight is 243 lbs (I’m 6’10”). I follow the nutrition protocol discussed in the book and strive to hit complete exhaustion on every workout with good form and repetitions."
  • Martin Vida before and after using the X3 bar workout system

    Martin Vida

    "It’s been 8.5 months since I started my journey with X3 bar. I’m down from 255 lbs and 35% bf to currently 220 lbs and 15% bf. Definitely the best investment I have ever made. X3, OMAD, and carnivore has become my lifestyle!"
  • Ted Radkoff before and after using the X3 bar workout system

    Ted Radkoff

    "An inch up on my arms, 6 inches down in my waist: seven months. This is far surpassed my expectations. Never picking up a weight again."
  • Dan Rodriguez before and after using the X3 bar workout system

    Dan Rodriguez

    "I followed Dr. Jaquish’s protocol, and used only the X3. I lost 2 inches around my waist and my weight stayed the same."
  • Mandy Watson before and after using the X3 bar workout system

    Mandy Watson

    "I lost 25 pounds! I’m really short so it shows incredibly, and with the X3 deadlifts, my hamstrings got bigger and stretched the skin on the back of my legs so I have no more cellulite!"
  • Patrick Tims before and after using the X3 bar workout system

    Patrick Tims

    "I’m Active Duty and have to maintain a certain level of conditioning for my annual physical fitness test. With X3 I’ve seen an increase in muscle mass and toning. In 8 months, my waist went from 35 to 31 and my run, definitely feels easier to do since my legs are stronger."
  • Keith Bout before and after using the X3 bar workout system

    Keith Bout

    "Best shape of my life, and I am in my 40’s. The X3 is super efficient. Not only do I use it, but I have the football team I coach using it too. Amazing results."
  • George Hayworth before and after using the X3 bar workout system

    George Hayworth

    "The results are outstanding but the other really surprising thing for me was how X3 hasn’t aggravated my existing injuries. In many ways it has rehabilitated them. I also went from 32 waist to 29-30 waist but had to have most of my pants tailored to be let out to make room for my bigger glutes."
  • Tim Bertrand before and after using the X3 bar workout system

    Tim Bertrand

    "In 12 weeks: Arms 5/8 bigger. Chest 7/8 bigger. Only worked out 10 min-ish per day. X3 is super efficient, and more effective than weight training. I am getting better results with this than with the 2 hour per day program I was on before."
  • Eric Bourgeois before and after using the X3 bar workout system

    Eric Bourgeois

    "My results in a year. I am a first responder so keeping fit is required, and now I am stronger and better conditioned than I ever imagined I could be. I liked the X3, but couldn’t understand the price. I started using just regular bands, but realized if I wanted to do meaningful strength training, the bands alone were hurting my wrists and ankles. NOW I understood X3 and pulled the trigger. Best decision I ever made."
  • Jason Young before and after using the X3 bar workout system

    Jason Young

    "In 15 months, I have gained 35 pounds of muscle using just X3 while maintaining the same body fat. I was always a hard gainer with weights, and hardly got any results. X3 changed everything."
  • Michael Patterson before and after using the X3 bar workout system

    Michael Patterson

    "In 90 days, worked through a few lingering injuries, lost 13 lbs of fat, and gained 18 lbs of muscle, and still gaining. Since watching my transformation, 4 of my friends have purchased X3s as well. Super happy with this thing!"
  • Thomas Kilcullen before and after using the X3 bar workout system

    Thomas Kilcullen

    "6 months with X3 only, and I look and feel completely different. Never going back to weights."
  • Bill Broadway before and after using the X3 bar workout system

    Bill Broadway

    "I swapped over 20 lbs of body fat for lean muscle in 12 weeks using X3 ONLY. My advice for others, follow the program to the letter. Do NOT deviate, and don’t add other stuff. Dr. J did this right."
  • Brett Delaney before and after using the X3 bar workout system

    Brett Delaney

    "My X3 is literally my favorite thing I own. In 9 months, I increased lung capacity, dropped 9 pounds of body fat, and added over 22 pounds of muscle. I’m now sitting comfortably around 9-10% body fat."
  • Todd Stratton before and after using the X3 bar workout system

    Todd Stratton

    "In 6 months, I gained 20 pounds of muscle and lost body fat at the same time, which was unexpected. X3 is fantastic."
  • Sean Williams before and after using the X3 bar workout system

    Sean Williams

    "In two months, I have seen fat loss, muscle gains, and definition. I love the accessibility of the product. My wife loves it too and she is also happy with her results. Adding to that, it has helped me in my job because it involves heavy lifting. The little time invested has yielded INCREDIBLE results!"
  • Sherry Waldman before and after using the X3 bar workout system

    Sherry Waldman

    "8 months of X3 and I have almost doubled my strength in every movement. My results are incredible."
  • Maykell Lorenzo before and after using the X3 bar workout system

    Maykell Lorenzo

    "I received greater gains from X3 in 11 weeks than in 20 years of lifting. I owned $10k of exercise equipment and sold it all now that I have my X3. Best device EVER for gaining muscle and losing body fat."
  • Rey Descalso before and after using the X3 bar workout system

    Rey Descalso

    "With weights, each injury meant 3 to 4 weeks of no exercise and reversal of any progress. I’ve had no injuries using the X3 even though the intensity of my workouts has increased exponentially. I used to walk around at 210. Now I’m 195. I can’t believe how good my body looks and feels. More muscular, more vascular, more flexible, and looking forward to the next x3 workout."
  • Raj Jayarama, MD before and after using the X3 bar workout system

    Raj Jayarama, MD

    "I am a physician and not only have my results been incredible, but I recommend X3 to my patients as well."
  • Greg Williams before and after using the X3 bar workout system

    Greg Williams

    "I’ve been noticing some pretty drastic results after only a month of X3. Before using the X3, I weighed about 270 lbs. After a month of using it, I weigh 235 lbs Feeling pretty good so far."
  • Matt Schweitzer before and after using the X3 bar workout system

    Matt Schweitzer

    "Best piece of workout equipment I’ve ever used. Massive strength gains, noticeable aesthetic changes in 4-5 weeks. The amount of muscle and lean mass is better than advertised. My DEXA and the mirror reflect massive changes."
  • Terrell Rainey before and after using the X3 bar workout system

    Terrell Rainey

    "X3 put 20 pounds of muscle on me in 24 weeks. I am on the road for work all the time, and by using X3, I have no compromise, better results than with weights, and I can do my workout ANYWHERE!"
  • Jeff Huguet before and after using the X3 bar workout system

    Jeff Huguet

    "Got my X3 in March. Been using it now for 8 months (the before pic is about 1 1/2 years ago). I’m 53 years old folks! X3 works. Plain and simple."
  • Sabian Beard before and after using the X3 bar workout system

    Sabian Beard

    "In the four months since I started X3 and adopted intermittent fasting, I’ve cut from 188 pounds at 12% body fat to 173 pounds at 7% body fat. I also sleep better and have better recovery. I’ve about doubled my vertical jump for football and ultimate frisbee, and even improved my running performance without any cardio work!"
  • Brandon Witters before and after using the X3 bar workout system

    Brandon Witters

    "Leaner and 30% stronger in all lifts on average. Strength gains even translate to weight lifting, though now I am 100% X3 for training."
  • Scott Blasz before and after using the X3 bar workout system

    Scott Blasz

    "I am 51, and 5’ 9. I was injured on the job and lifting weights was not an option. When I started using the X3, I weighed 247 pounds, and was 45-50% body fat. Now, 5 months later, I weigh 193 pounds and I’m about 19-23% body fat."

About the Inventor

John Jaquish, PhD, is a Wall Street Journal Best Selling author of Weightlifting Is a Waste of Time and inventor of OsteoStrong, a bone density building medical device that has reversed osteoporosis for thousands and created more powerful, fracture-resistant athletes across 300 clinics worldwide.

While researching bone density, Dr. Jaquish quantified the variance in power capacities from weak to strong ranges, which led to his second invention, X3. Research indicates that X3 safely builds muscle much faster than conventional lifting.

Dr. Jaquish has been featured on many top health podcasts and was nominated for the National Medal of Science.
