Full Transcript

Joanne: The before and after pictures. Look at them, they say it all. These people did not take any pills, or go on some crazy diet, or run two marathons, two to five marathons. They simply changed their workout tool to the X3 Bar exercise band bar system. So we have the inventor of this tool here today, Dr. John Jaquish. He’s here to show us the science behind this tool because, doctor, you’re a scientist, right?

A portable, all-in-one home gym system

Dr. John Jaquish: I am, yeah, probably more inventor than a scientist. Not everybody invents stuff. So, I developed a medical device 13 years ago to treat my mother’s osteoporosis. So, what ended up happening was we tested this device and it puts huge forces through the body. It’s called OsteoStrong.

Joanne: Right.

Dr. John Jaquish: It puts huge forces through the body in impact-ready positions. So, if I go to trip and fall I’m going to protect myself like this. So, I noticed in these positions that people are seven times stronger in that impact-ready position than they are in the weaker ranges of motion. I knew I was the only guy that had quantified that, so I wanted to develop a device for muscular training. This is it. So, here I’m going to get in a chest press position.

Joanne: So, it comes with the bar. It comes with five different bands?

Dr. John Jaquish: Four different bands and then the elite one is extra. When I crosstalk

Joanne: There’s no way.

Dr. John Jaquish: … over 600 pounds. This is a chest press where I’m holding close to 300 pounds at the top, but the weight diminishes when I get to a weaker range of motion so I can actually go through movements and engage the body in accordance to the biomechanics. So, the weight gets heavier as the musculature is capable of delivering more power, which means a greater level of fatigue faster. So, the workouts are like 10 minutes, and there’s even more growth than you’ve ever seen.

Joanne: This is yours over here.

Speaker 3: You’re not going to hook me up on this one here, 600 pounds? Oh my gosh.

Joanne: We’re going to try this because it’s intense. All you need is 10 minutes a day.

Dr. John Jaquish: All right, so Joanne’s going to do the overhead press, the squat. Get the bar up here. Go ahead and stand up.

Joanne: Oh, my gosh.

Dr. John Jaquish: Put your hands around.

Speaker 3: Put my hands around?

Dr. John Jaquish: Yeah.

Speaker 3: Okay.

Dr. John Jaquish: And now just stand up and do a bicep curl where you pull the elbows back at the top. Perfect.

Speaker 3: Now, what’s the weight range that we’re working with here with this strap?

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

Dr. John Jaquish: So, this one goes to 70 pounds at the top, but she may be closer to 40 at the bottom. This one goes to about 50 at the top, but it might be 20 at the bottom.

Speaker 3: And you can definitely feel it. You can feel the difference.

Joanne: This is crazy. This is… People say this is all you need, so I got to toss it to break guys. For more information go to We’ll keep working out, guys. See you in just a few minutes.
