Summary of Your Future Benefits When You Employ the ISOCHAIN with Paul Wade’s Progressive Masterplan for Extreme Strength Development

Super Economical:
One piece of equipment meets most of your physical training needs with nothing extra to purchase.

Super Convenient:
Fixed device requiring no plate changes or additional weights. Minimal storage requirements. Perfect for at-home training.

Saves Your Joints from Wear, Tear and Injury:
Because your limbs stay in a fixed position and don’t move under tension, injured or vulnerable joints can be trained hard with zero grinding, therefore with less or zero pain or damage.

Enhanced Recovery:
Because of the lack of concentric or eccentric motion, high-tension isometrics causes less damage to muscle fibers; it results in less soreness and techniques can be performed with greater frequency than conventional methods.

Now You Can Finally Track Your Progress! Why the ISOCHAIN Represents a Quantum Leap In Isometric Training Efficiency...

With all previous isometric training devices it’s been impossible to track your progress which means:

1. There’s no way to know how much force you are generating. This is a massive stumbling block because Progressive Training is the Holy Grail of all strength methods. And without this data you cannot establish progress. This not only makes programming problematic but it essentially kills training motivation. You are training blind and have literally no idea what you’re doing, or capable of doing, in terms of work load.

2. There’s zero loading reflex. Normally the nervous system puts protective blocks on your force output. It only allows maximum force to be expressed when there is a legitimate load to be dealt with. Example: pushing against a tree versus holding a tree from crushing you as it blows over.

Unfortunately these two issues have previously proven insurmountable – up until now. Because the ISOCHAIN solves them both...

Rated 10/10 Everything I had hoped for!
 
By Dan Skully / Dublin, OH, United States

I preordered the Isochain as an Isochain Advocate. I read the data, and I was convinced. Suffice to say, I had high expectations.
For context, I'm in my late 30's, and a former football player. I started using kettlebells in my late 20's, and more recently I've trained using the Convict Conditioning program. The problem that I run into with training is consistency. When I learned to lift, it was critical to go to failure every set and go full-bore every workout. That's just not realistic after a hard day at work, so any time work would get busy, I was sacrificing workouts because I didn't have either the time, or the energy to go all out. The COVID lockdown was a big setback as well; because I work in an ICU, my wife wanted me to quarantine on my off days this spring so I didn't infect her or our son. The result was a lot of sitting around.
The Isochain has solved a few problems for me:
One, it's extremely efficient. I can get a good full-body workout in 30 minutes. Even when I get busy, I can find 30 minutes nearly every day.
Two, it's effective. When I read that I could improve my strength by 5% per week, I was a little skeptical. But that's about where I am. Nearly 30% stronger in squats, deadlifts, bent rows and overhead press over 6 weeks. The different modes deserve a shout out here for helping to track this progress.
Three, even when I don't have my "A game", I still feel like I get the maximum out of what I do have. Those days where I skip a workout because I feel like I can't go all out are over. As long as I give the best effort I have on a given day, the Isochain turns that into the best workout I can get with that effort.
Four, it's safe. I've had problems with my back, my knees, and triceps tendons over the years. Zero issues with any of those. As an added bonus, my 3 year old son can be in the room with me and I don't worry about him getting hurt the way I would if I were lifting a barbell or swinging a kettlebell. I like that I can set a good example for him and keep him safe.
Five, I don't have much soreness after a workout. The isometric manual mentions "virgin soreness" early on, which you then grow out of. That was my exact experience, the soreness has been mild at most after the first 3-4 weeks. And even at my most sore, it was far less than what I've had before with traditional weight lifting.
Six, the space requirements are minimal. For a lot of the exercises, you only need slightly more space than the size of the base.

A few caveats (not negatives, per se):
One, I have noticed more improvement in my numbers for exercises where I'm strong enough to stretch the spring a little. Removal of cortical inhibition makes a difference.
Two, there is a bit of a learning curve with isometrics if you're accustomed to traditional weights. It's just different pushing as hard as you can against something that doesn't move. It gets better with practice.
Three, the bottom carabiner likes to flip so the narrow side is up, around the chain. This can be a tight enough fit that it takes some effort to get it repositioned so the chain length can be adjusted. I solved this problem by taking a long twist-tie and making a figure-8 around the sides of the carabiner so that the narrow portion stays down, adjacent to the spring. That keeps the large part up by the chain for easy adjustments.
Four, the chain is 90 links long, but doesn't have an easy way to identify where you are. I painted a stripe on every 10th link, so that I can easily track chain position for each exercise.

All told, I really enjoy this device, and the results I'm getting. I'm very excited to see where I am in a few more months.

TL;DR - Great device, great results. A few minor downsides were remedied easily with some minor tweaks on my part.

 
Rated 10/10 If you are over 60, then you need an ISO-CHAIN!
 
By Doug Bennett / North Little Rock, Arkansas, United States

I was an Iso-Chain Advocate and patiently waited for months to receive my Iso-Chain. I just have to say it was worth the wait! I have been a customer of Dragon Door for many years and I own several "pairs" of kettlebells. I am 62 years old, and due to my activities, I have several old injuries that seem to revisit me when I embark on an ambitious kettlebell program, most notably a left shoulder injury that reappears with just a simple loss of form on a kettlebell movement. And of course, upon embarking on my Iso-Chain journey, I experienced another setback. While repairing a plumbing problem at one of my buildings I fall and bruise a rib.... Another setback!
My original purpose for embarking on an isometric program was for blood pressure control and to keep me off meds. Now that the rib problem has healed I am on my way with the Iso-Chain. I can say that almost immediately, my shoulder is much better! No more constant nagging pain throughout the day. I am starting to see some growth in upper body muscles, and most importantly, I feel stronger and seem to be much more in tune with my body. Knee aches and pains (yeah, I almost forgot about those, I am so used too them) have all but disappeared as well. I have noticed a slight improvement in the blood pressure numbers and I am sure once I get deeper into the programs, these numbers will get to where I want them to be.
In my opinion, everyone over the age of 60 should own and use one of these devices! Just the freedom from pain is well worth the investment, not to mention the other benefits!
At this point, I also have the mention the fact that Dragon Door's customer service is 2nd to none. I prefer using the Load mode and counting the beeps. To my chagrin, my Iso-chain started refusing to go into Load mode. After several minutes of struggling, pulling out batteries and resetting the device I could finally get it to cooperate. Initially I was convinced that I was doing something wrong. I finally reached out to Dragon Door and they promptly replaced the control bar. No questions asked! This is Customer Service at it's finest! For anyone looking for cutting edge physical fitness solutions, Dragon Door is the hands down leader in the field.
Highly Recommended!
(I have also introduced my 15 year old grandson to the ISO-CHAIN! I am using him as a test guinea pig! I will report on his progress once I get him a little more consistent with his workouts.)

 
Rated 10/10 Best thing I've ever used for fitness
 
By Ted Croushore / Springfield, VA, USA

Three weeks on the chain...started 12/14 with Promethean 3x a week. As of today's session, I'm up 30% on my max and about the same on my 6 set average for deadlifts, curls, and shoulder press. I'm trying to keep it under 35 minutes with warm up and cool down.

Two things: 1) I'm hyped for the Isochain; and 2) for me, the app is a must.

 
Rated 10/10 Best piece of equipment I have ever bought!
 
By Brad Mechor / Calgary, AB, Canada

I recently purchased the Isochain and have to say that I am absolutely in love with it!
I have bought a ton of fitness equipment in the past (ask my wife!) and I can honestly say that this is the first piece of equipment I look forward to using almost daily!
Very functional and have noticed great strength gains in the first month since I got it. I love to check the amount of force generated with each movement and have watched numbers climb!
If I could have only 1 piece of equipment it would be without hesitation, the Isochain!

 
Rated 10/10 You guys are onto something with this thing!
 
By Thomas Hauge / Egaa, Aarhus, Denmark

"Initial" review after approx. 1 month's training and experimentation. Brief background: 57 years of age, 36 years of gym/barbell training, 5 years of convict conditioning. Got intrigued by the isochain and bought it. Bar-console was defective, Dragon Door sent a replacement immediately, sterling service! The manual lives up to its title, if it's isometrics, it's in there. Solidly sourced, too! I've tried isometrics several times during my training life, and Dragon Door is right : being able to MEASURE what you are doing IS the game changer. Between measuring and manual, you'll know both what you're doing and why.

Time or recovery ability constraints will dictate how many exercises, how many sets and how many workouts-a-week you can do, but you will be making an informed choice, and be able to check out if the choice is working as intended. Personally, I dived in with an 1-1 to isochain conversion of my usual exercises, of course doing 6x6, and hey, if you can isos every day, that's the way to go, no?

No. It's a bit insidious, really. You DO recover fast from isos, and it there IS something about the "biofeedback" of the console that makes you eager to hit the next workout a.s.a.p. -- but the console will also tell you when you aren't ready yet; an important fringe benefit: you can always do a bit of ballistic cheating with a barbell, effectively getting by with less effort. If you cheat on the isochain, your bluff will be called immediately -- no beeps.

So I've (reluctantly, those iso's ARE addictive) brought my program down to seven exercises and the frequency down to 4-5 a week. I test the transfer of strength regularly, by doing my previous convict conditioning exercises, and I can confidently report that it DOES carry over, and I am NOT experiencing any "angle specificity"; the CC bodyweight moves are a lot easier already, and I am only doing that program once every 7-10 days, so the improvement can ONLY come from the iso workouts.

But there are far more important benefits from the isochain. My wife has been struggling for many years to find a "safe" way to train. A 110-pound ICU nurse, she once had to catch a 240-pound unconscious patient falling out of bed, and do so from a lousy angle. One shoulder and two back surgeries later, her usual gym/barbell-style training was out. Calisthenics have been adequate, but with six fused vertebrae and brittle rotator cuff, some positions and movements are off-limits, and that includes some that are required resonably strenght-inducing loads. OTOH, building strength is imperative to support the back and shoulder. Checkmate.

Enter the isochain. Now she can find the optimal/safe/strongest position for every muscle group, and THEN "pile it on". As an example, she can only "afford" to bend knees and hip 10-15 degrees when doing a deadlift. To get effect-inducing load in that position with a barbell would be high-risk, or require a power rack -- and even with the power rack, the barbell could prove too heavy, and cause injury. With the isochain, there is only load when she actually pulls, and it "disappears" the moment she stops pulling. With the CONSOLE on the isochain, we can keep the intensity on a "safe" level, and still within the range needed for progress.

Short of a roomful of advanced training machines, I can't imagine any other training tech providing that combo of safety and effectiveness. The isochain delivers that roomful of advanced training machines in a tool that takes up less than one square meter (I'm european).

... So if you guys at Dragon Door aren't already marketing the isochain aggressively to physical therapists, you should. Muscleheads like yours truly COULD go on slinging iron (though I'm not likely to ever do that again), but a lot of people who'd never be ABLE to benefit from the gym could do themselves a world of good with an isochain.

You guys are on to something with this thing!

 
Rated 10/10 Huge break through
 
By Edson Castillo / Streamwood, Illinois, USA

Been dedicated to training for performance for 40 + years. I competed in football at the college level and after, took up different disciplines of martial arts. I've taught professionally from general fitness to professional athletes.

I can't remember a time when a training modality had this much of a positive effect on me. You must purchase a copy of the Ultimate Isometrics Manual with the Isochain. My training is renewed, the results have been incredible so far and there is so much more to experiment with. All backed by scientific references.

I'm grateful to Paul Wade and the Dragon Door Research Group.

 
Rated 9/10 A true game changer
 
By Matt Schifferle / Littlton, CO, USA

It's hard to put the value of quantifying isometrics with audio feedback into words. It truly is one of those things you have to experience to understand the value behind it.

It took me a couple of workouts to really "get it" and understand what the programming of the Isochain does to the isometric workout. Once I understood what was really going on, I wondered how the heck I was able to effectively train true strength isometrics without that feedback.

Since then, working out without such feedback feels like I'm just training blind.

 
Rated 9/10 Great isometric device
 
By Doug Zale / Valparaiso, IN, United States

The Isochain solves the biggest problem with isometrics especially for someone used to free weights' progression! You can't know the effort of your pull from one pull to the next in one workout let alone over time. The Isochain solves this beautifully. You can set a specific load and increase it progressively over time noting the load, the reps achieved, the max achieved, and even an average.
My only real problem is the ease of moving the handle up and down the chain and noting which link to hook into. Counting links is tedious but the only good way. I've tried marking the links with colored tape but it comes off quickly. I?m considering colored plastic locking strap ties next. This is a minor quirk that can be worked around. I still love it for its safety, especially for the deadlifts.

 
Rated 10/10 Fantastic Training Device
 
By Jens Bunge / Frankenthal, Rheinland-Pfalz, Germany

I've been training for 40 years now, starting with isometrics in the form of a Bullworker and a power twister as a 17 year old. Then continued exercising with dumbbells and barbells. But in recent years I came back to isometric exercises again. So I was very excited to see the Isochain advertized in Paul Wades "Ultimate Isometrics Manual" which I purchased last fall. I ordered one on a Sunday and was surprised that it arrived all the way from US on Thursday morning! Great customer service from Dragon Door and FedEx!
Since then, I've been training with this fantastic training device at least twice a week - alternating isometric with dynamic workouts -
and see steady gains in my strength. My muscles are able to contract harder than ever,
and a workout doesn't last longer than 15 - 18 minutes. This is a very effective and time-efficient form of training! The concept of having an electronic unit in order to measure the applied force and monitor progress over time is nothing less than ingenious! I'm glad I bought the Isochain and highly recommend it to anyone who wants to take the guesswork out of his/her isometric training!

 
Rated 8/10 Great, Could be Even Better
 
By Jeff Pitman / Menomonie, WI, United States

The Isochain does provides significant improvements in weight training, for three reasons:
- It uses the principle of isometric exercise
- It greatly simplifies the objectivity of measuring results. The "Maximum" and "Average" recording features for each exercise are truly brilliant additions, and very simple to use!
- The Isochain also reduces the possibility of injuries which always lurk when hefting heavy weights.
For these reasons alone it should be the go-to exercise device for serious weight lifting practitioners.

There are minor design/manufacturing elements that could be improved however:
- The individual links of chain should be slightly wider across their interior; currently switching from one link to another is needlessly a bit cumbersome.
- The screw bolt and its attachment point on the underside of the handle is insufficiently strong (mine bent during the second week of use.)
- I recommend clip-on rubber/plastic rings be attached to chain links to identify the precise link needed for quick changes between exercises. (I've been using tape, but the tape doesn't last long.)

The manual that accompanies the ISOCHAIN is well worth reading, regardless of your current level of expertise. A great improvement for strength training!
