Isometric ­ from the Greek isos, which means "the same", and metron which means "size".

Isometrics means pitting your muscles against an immovable object and holding for a period of time ­ usually for a slow count of 10.

An assortment of webbing hardware and homemade handles. (see the Miscellaneous page for webbing tips and ideas)

Here are some examples of using webbing as an Isometric exerciser. Sliders enable quick adjustments in the lengths of webbing.

Isometrics utilizing some leverage

­ gruntbrain

The Alexander Zass Isometric ExerciserAlexander Zass was a noted strongman from the early 20th century. His claim to fame washis ability to bend thick iron bars and to snap chains with his bare hands. What makes Zassso unique was not only his ability to perform these astounding feats of strength, but the wayin which he developed the strength to be able to do these things.

As a Russian prisoner of war held in Austrian prison camps during World War I, hedeveloped a powerful physique and tremendous strength by pulling on his prison bars andchains. He had been a strong man prior to the war, having worked out religiously as a youngman, but as a prisoner, he discovered the means by which extraordinary strength could beachieved. At one point, Zass found himself shackled in solitary confinement. He wasconcerned that, being unable to exercise properly, he would deteriorate and loose thestrength and physique he had spent so many years developing. It was then that he beganpulling on his chains and prison bars as a means of exercise. To his great delight, hediscovered that this type of training actually increased his strength. Finally, when the timewas right, he bent the bars to his prison window, snapped the chains of his manacles, bentone of the bars clear around to be used as a j­hook for scaling a wall, and made good hisescape! After the war, he went on the road as a strongman and gained fame throughoutEurope and England as "The Amazing Samson" . He also sold a course of strength­buildingutilizing the methods he had developed as a prisoner of war, and which he, himself,practiced throughout his illustrious career.

With the advent of the Internet and a growing interest in the early Iron Men, AlexanderZass has been resurrected from virtual obscurity and is today being hailed by many as the Father of Isometrics. Our modern dayfamiliarity with Alexander Zass, as well as with many of the Iron Men of the Golden Era, is due to the efforts of two men, Roger Fillaryand Gil Waldron. These two men, along with contributions made by Gordon Anderson, have worked tirelessly and continue to do so tochronicle the photos, lives, and workout programs of the pioneers of physical culture on their site, Sandow . This is the definitive site onthe subject, and both Roger Fillary and Gil Waldron deserve enormous credit and thanks for their important contribution to posterity.You can go to this site to find Alexander Zass's fascinating autobiography. Not only did he live an extraordinary and exciting life, buthis well written autobiagraphy also lends insite into European and British culture at the turn of the twentieth century.

Through a lot of research and digging, photos of Alexander Zass demonstrating his exerciser have surfaced, but the actual course ofexercise that he sold has yet to be found. Among practitioners of Isometrics, the Alexander Zass course is the "Holy Grail" of workoutprograms, and a worldwide hunt ensues in hopes of finding it.

And now, tao has made his own Alexander Zass exerciser and has developed his own program of exercise.

The Roller Iso­cizer

Here's an Isometric device that will enable you to move as quickly as possible from exercise to exercise. All you've got to do is roll apipe to the desired position. The magic ingredients here are webbing and athletic tape. A couple of rolls around the tape, and thewebbing binds and will not slip!

The quickness with which you can adjust the height of the bar enables you to easily perform the same exercise from three differentpositions, like curls for example, ensuring overall development of the biceps.

Here's how to create this exerciser:

9/22/2015 isometrics

http://www.angelfire.com/ny5/shenandoah/Grunt/Isometrics.html 5/19

Take a 15' length of 1" webbing andcreate a large loop by tying the endsinto a knot.

Attach the webbing to a an athletic­taped pipe via a slip knot.The pipe shown here is a 12" length of 1" PVC inserted into a 11/2" rubber utility hose for a wide, supple grip.

Here are some examples of exercises that can be performed with the Roller Iso­cizer:

Isotonic/Bodyweight exercises can also be performed using this device, as shown on the right. Lean back and use it as a wrist roller!

Now, you might not have a playground across the street. Here's an easy to make door attachment. Slip a length of 1" webbing, or ropethrough a short length of PVC whose ends have been sanded and rounded, tie a tight square knot and push the knot into the pipe. Youcan add a carbinger, as shown, or an s­hook with which to attach your Roller Iso­sizer. Slip the attachment under or over a door, andshut the door. You could make two of 'em ­ one for atop a door, and one for underneath.

The ability to quickly adjust to any length also enables you to perform isometrics from different positions. For example, you couldperform curls or shoulder presses from low, middle, and high positions.

Isometric Stand

Here's my idea for an isometric machine. Basically it's comprised of two 7 foot 4 x 4's with1" holes drilled 4" on center for 1" wooden dowels. The 4 x 4's are jointed at the bottom andsecured to the base structure with (2) 3/8" bolts ea. side, and 2 x 4 bracing, back and front.Using a 5' steel bar or pipe, you could slip the dowels into select holes on either side andperform a myriad of barbell type isometrics ranging from dead lifts through squats and upto presses. The lower holes could be used for pushups, and the top holes, which are drilledangled slightly downwards could be used for chinups.

Making a longer platform, say 4' x 4', or even 4' x 6', would make this machine moreversatile. You would be able to attach heavybags, resistance bands, Jungle Gyms, PowerRings, webbing exercisers, wrist rollers, etc.

Shown here are some Isometric exercises being performed on a machine of similar design:

Iso Strap

The Iso Strap essentially works the same way as the Isometric Stand above. You stand on the strap and grab hold of two handles oneither side. The Iso Strap consists of a long length of 1 1/2" webbing with a fixed handle on one end, and multiple holes in which to slip

9/22/2015 isometrics

http://www.angelfire.com/ny5/shenandoah/Grunt/Isometrics.html 8/19

another handle with a fixed hook. An over door/underdoor attachment greatly increases the number of exercises that can beperformed. With the door attachment secured at the top of a closed door, you can perform push down/pull down exercises. The doorattachment positioned at the bottom of the door makes the strap ideal for triceps curls. You can lower or raise the heights of thehandles by simply stepping away or closer to the door.

You add as many holes as you want to, whenever you want to, wherever you want to, allowing as many isometric exercises that you canconceive of. You can do everything from iso squats, through iso bench presses (with the strap against your back), on up to iso militarypresses. The quick adjustment also enables you to perform the same exercise from various positions ­ curls, for example. You couldhave your Iso Strap set up to do curls from the bottom, middle, and top of the exercise, resulting in full development of the biceps. Youcan do concentration curls by sitting down and holding the fixed handle in one hand with your elbow braced against the inside of yourknee, while holding the strap down with the foot of your other leg. This would allow you to perform concentration curls from threedifferent positions super­fast.

The Iso Strap will also enable you to perform Alexander Zass type isos as seen above.

Here's how to make it:

Determine the length of 1 1/2" webbing you need by standing on a length of webbing and raising your hands straight up overhead,holding the webbing in each hand, and then measure and cut that length of webbing. Add a bit more than you feel you need to assurethat it is long enough. You can always cut off the excess. In my case, at a height of 5'9", I cut a length sixteen feet long and ended upneeding fourteen feet. Singe the cut ends with a flame to seal them and to prevent them from unraveling. Do this with every length ofwebbing that you cut.

I went looking for a couple of eye hooks of the type found at Lowy Enterprises. Of course, there isn't ahardware store in the entire free world that carries this item which millions of people would have practical usesfor, so I got a couple of S hooks from Ace Hardware and they allowed me to use their vice to smoosh one end ofthe S hooks into an eye.

I made two 5" handles from 3/4" PVC with rubber pipe insulation. Sand and smooth theedges of the PVC. Cut two lengths of 1" webbing 24" long, slip one of the hooks over one ofthe lengths of webbing, slip the webbing through the handles, tie a good, tight square knoton each, and then tuck the square knots into the handles. There is no need for the webbing tobe of equal length when tied. If I had been making a devise that required the webbing to beof equal length, then I would have sewn the webbing. But why create work for yourself whenyou don't have to?

Using a short length of PVC and a 12" length of 1" webbing, make a door attachment in the samemanner that the handles were made. You'll notice a narrow piece of vinyl tape wrapped around thehook. That's there to close up the gap that you'll see in the picture of the S hook above, to preventthe hook from slipping off of the webbing. If I had been using rope instead of webbing, this wouldn'tbe a concern. The tape works just fine, but at some point I might close that gap with some JB Weldjust to have a finished product.

9/22/2015 isometrics

Secure the fixed handle to one end of the strap using a slider.

Here's how you determine where to put the holes in the strap:

Stand on the strap and, with one hand, lift the fixed handle to the position you want your hands to be in for a particular iso exercise.Take hold of the other side of the strap with your other hand and bring both hands together in front of you, pulling the strap taut.Place the thumb of your hand holding the strap to where the fixed handle is attached to the strap on the other side. From where yourthumb is located, measure down 3" and make a mark with a marking pen. The subtraction of 3" takes into account the length of thehook on the detachable handle.

I punched holes into the webbing using the largest punch attachment from an inexpensive leatherpunch kit I got at Micheal's.

Secure the holes with eyelets. Eyelet kits can be found at either fabric stores or hardware stores, orfrom the webbing links shown on our Resources page.

As well as an Isometrics Exerciser, the Iso Strap, together with the door attachment, also makes aworld­class Bodyweight Exerciser! See the Bodyweight page for ideas, in particular, the 15 Minute Door Gym.

http://www.angelfire.com/ny5/shenandoah/Grunt/Isometrics.html 10/19

Here’s a unique adjustable strap utilizing a slider with rounded edges that will allow you to adjust any nylon or neoprene strap withease during your workouts. As you adjust the strap to desired lengths, you can mark the settings at the slider with a marking pen.

Step 1: Take one end of the belt strap and loop itthrough as shown. This is the adjustable part of

the belt strap.

Step 2: Take the other end of the belt strap andloop it through the same way as shown in Step 1.

Loop the strap over the buckle and back throughthe other end of the buckle. This is the stationary

end of the strap.

Voila'! You're good to go. Use your iso strap as is

or add 1" utility hoses for handles as shownabove.

The Cinch Isosizer

9/22/2015 isometrics

http://www.angelfire.com/ny5/shenandoah/Grunt/Isometrics.html 11/19

And making quick adjustments is a "cinch" with this iso strap! A cinch is the same mechanism used to tighten the saddle around ahorse. You can use either D rings or O rings as seen here. Simply slip the end of webbing over and through as shown, and that's it.Once tightened, it will not budge, and then to loosen it, simply loosen it. It's that easy. Note also, that the belt has been tied around therings. A slider could have been used, or the belt could have been sewn, but why create more expense or work when you don't have to?And note also that an old martial arts belt makes a great, heavy duty strap.

As with the Easy Slide Iso Strap shown above, you can use any length of webbing you choose for all your iso or bodyweight needs.

Looking at the top of this page, you'll see a picture showing the cinch set up utilizing a carbinger which can be hooked onto something,greatly increasing your range of exercises.

VariablesWhen it comes to creating your own equipment, virtually anything you can think of is possible.

Here is an iso exerciser thatenables you to pull with palmsinward, outward, upward ordownward. Think hammer curlsor triceps curls. The top handleis a PVC pipe and the sidehandles are rubber pipeinsulation wrapped withelectrician's tape.

This exerciser gives you a choiceof using a length of PVC or somerubber utility hose as a handle.Note that a plastic slider can beused for most your needs,although a metal slider insuresmaximum strength.

For this easily made device, arope is slipped through a coupleof foam bicycle handles and thentied on the ends. Bicycle handlesprovide numerous options, fromsimple foam, or for the ultimatein decadence, molded rubber.The exerciser shown above alsodemonstrates how easily you canmake dedicated isosizers. Make abunch of 'em for variousexercises! You can also combine

9/22/2015 isometrics

a few of them by looping themtogether for readily availablediffering lengths.

Yet another quick method of attaching a handle to arope ­ just slip the ends of a rope through the handleand tie knots on either end.

Here's a "grip assist" exerciser. Slip yourfingers between the handle and the webbing,and the webbing will keep your hand held fastagainst the handle. One knot is all that's neededhere. Just slip the ends of webbing through ahandle and then slip one of those ends aroundand through again.

Quick­Change Iso Handles

9/22/2015 isometrics

http://www.angelfire.com/ny5/shenandoah/Grunt/Isometrics.html 13/19

This is a fantastic setup which enables you to move quickly from one isometric exercise to another by simply gripping and releasing thehandles.

I slipped the ends of two tight­woven, polyester, 3/8" thick, fifteen foot ropes through either end of two foam rubber bicycle grips (Ifyou're taller than I am, 5'9", you might want to use longer ropes). Pull the ends of the ropes through the handles to create loops, as seenabove, being careful to keep the extended ends of the ropes equal in length. From there, you simply stand on the loops and lift thehandles to a desired position. At that position, just grip the handles and perform an isometric exercise. You don't have to grip veryhard to hold the rope fast. I'd imagine that doing this over an extended period of time will contribute to some pretty hefty forearmdevelopment.

The beauty of this exerciser is being able to move quickly from one exercise to another. You can easily perform isos from variouspositions of the same exercise, i.e., curls ­ low, middle, and high. With the handles at a specific height, you can perform variousexercises that utilize the same height, i.e., curls, triceps extensions, lateral raises.

Obviously, the progression on this exercizer is continuously upward, so, for a full isometric workout, you'd want to start low and workyour way up. You could begin with squats, then deadlifts, and then up to back rows, and on to curls and extensions, and end withtriceps curls and presses, and anything in between you can think of. Remember, too, that each of the exercises can be performed frommultiple positions.

The Deluxe Model

I decided to make a foot stand, as I'd rather have the loops to my sides rather than under my feet, especially for squats. I made thisstand from 1 1/2" webbing and a couple of D rings. I could have just as easily used a rope to connect the two loops, but I have lots ofwebbing and related hardware, and I like the idea of a finished, professional looking product.

Exercises

ADDENDUM: When using this thing, I found that often one length of rope wouldslide through the handle while the other length of rope wouldn't, causing me torun out of rope on the high isometrics. I solved this problem by aligning the endsof rope so that both lengths were even, and then binding them together down atthe base. I first wrapped them with some vinyl tape to hold them in place and thenI tightly tied them with a length of waxed string. Now my Quick­Change IsoHandles work perfectly!

New and Improved!

Even More Better......I discovered through use that the ropes have a tendency to occasonally bind within the handles. So, I justeliminated the handles all together and replaced the ropes with 5/8" thick rope, providing a nice, thick, substantial grip. I simply crossthe ropes in my hands, lift, and grip at my various iso stations. Works great, and surprisingly little grip effort is needed to hold the

Yielding Isometrics

Yielding Isometrics means challenging your muscles against an object that moves but increases in resistance as it is moved to the pointto where it can no longer be moved. By performing this type of exercise repeatedly, a person will be able to push this object further andfurther with each succesive attempt, each time challenging the muscle to optimum effort resulting in maximum growth and strengthincrease. i.e., eliminating the middle man, i.e., the ten repetitions, and going straight for the juglar.

ChowflexThis nifty, handy little device provides real isokinetic resistance! Don't laugh! This Four Paws Rough andRugged Ring which can be found in any well­stocked pet store makes a perfect exerciser! It is a 7" ring ofnatural gum rubber which provides just the right amount of elasticity for maximum isotonic exercise....andit floats!

A Kinder, Gentler Doggy Ring:

Tape pipe insulation to the dog ring that is mentioned in the Homemade Equipment site. With 2 ringscombined with webbing the exercises in www.ringtraining.com can be done comfortably; the rings tend topinch hands so the insulation minimizes the pinching.

The Mega Ring

Here's another outstanding isokinetic exerciser ­ an extra rubber reinforced mountain bike inner tube! With this device you couldperform a plethora of exercises; hack squats, curls, the archer, stand on it and hold it behind your back with both hands and perform abent over triceps extensions, back rows, loop it over a doorway and do triceps push­downs and other pull down exercises, hold itbehind your back with one hand and grab the other end high up with the other hand and then spread spread your arms apart hittingthe triceps from both directions, fold it up a few times and then wring it like a towel.

Hook it around a door knob and do a one arm press or triceps curl, or various pulling exercises.

Fold the Mega Ring over once for stronger resistance or for exercises requiring a shorter expanse.

The possibilities are virtually endless! Just great!

Variable Resistance Isokinetic ExerciserFor this exerciser, tape together a bunch of elastic resistance cables or surgical tubing as shown. From there, simply grab a handful forany amount of resistance you want. You could wrap it around a chinup bar for pull­down exercises. No chinup bar? Tie a length ofwebbing around the center and create a big knot. Place the webbing over a door and then shut the door tightly.
