You Are 7 Times Stronger Than You Realize
10 years ago, a scientist invented a medical device to grow bone density since his mother had low bone density and knew he could fix it.
The device fixed his mother's bone density as well as tens of thousands of others, but he made another big discovery. He saw that when people are in impact-ready positions, they were seven times stronger than what weights would allow at the gym. This means that when you lift weights you are overloading joints while under-loading muscle. Exactly why so many fail to see results.
What if you could change the weight as you move!?
He created some of the world's most powerful latex bands: 50–100 times the power of typical fitness bands. The only challenge was that these bands would injure wrists and ankles if used alone.
He then invented a powerful olympic resistance band bar and ground plate to protect joints and deliver massive variable power for RAPID GROWTH!
Unlock Your Potential With X3
- Beginning with full range reps, and hitting about 500 lbs (237 kg) at peak, continue until zone A cannot be reached
- Continue doing half reps using only Zones B & C at about 300 lbs (136 kg) until B cannot be reached. Usually 5 more reps.
- The last 2–3 reps have the user barely moving the bar because of the extreme exhaustion with about 100 lbs (45 kgs), just in Zone C.
- After this process, the muscle is taken to fatigue to a far greater level. Greater fatigue = Aggressive growth
Included With X3
- X3 Elite Bar – Specially machined alloy steel resistance band bar with internal bearings, like an Olympic bar, so that the grip is always optimized
- Ground Plate – Heavy Duty Ground Plate Protects ankles from high forces produced by X3
- Custom Engineered Resistance Bands up to 600 lbs (272 kg) – Includes Extra-Light, Light, Medium, and Heavy. (600+ lb Elite Band sold separately) bands made from layered latex of exceptional thickness
- Engineered to support over 600 lbs (272 kg) of resistance
Also Included, 12-Week X3 Workout Program
- Entry Level Guidance on Form and Technique
- Advanced Workout Methods for Accelerating Growth
- Tips On When to Exercise and When to Rest
- Nutritional Meals with Little to No Prep
- Hacks for Greater Results

Our Customers Love the X3 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"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."
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"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."
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."
Sherry Waldman"8 months of X3 and I have almost doubled my strength in every movement. My results are incredible."
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"I followed Dr. Jaquish’s protocol, and used only the X3. I lost 2 inches around my waist and my weight stayed the same."
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"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"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."
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!"
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"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"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"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"6 months with X3 only, and I look and feel completely different. Never going back to weights."
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."
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."
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"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"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"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"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"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 X3 builds muscle much faster than conventional lifting in far less time and with the lowest risk of joint injury.
Dr. Jaquish has been featured on many top health podcasts and speaks at scientific conferences all over the world. He is a research professor at Rushmore University and a nominee for the National Medal of Science.
