"As a professor emeritus of
biomechanics and kinesiology, I've always been interested in human
movement, and in particular, how it related to athletes. I started
working with athletes in the 70s while I was teaching at California
State University Fullerton, and in the late 80s, I decided
to open my own sports training company.
Because I focus on the biomechanics and kinesiology of human
movement, I'm able to work with any kind of athlete. I create a
specialized technique analysis for each individual. For example,
after watching a video of an athlete engaged in his or her sport, I
can analyze movements and look for ways to increase effectiveness
and efficiency. Then, I develop exercises that require the same
speed, motions and neuromuscular pathways to accurately duplicate
the movement (skill technique) the athlete needs to execute during
This training isn't about how strong you can get in a gym.
It's about how much better you get on the field. The exercises have
to be specialized and tailored to that particular athlete, and they
require the right kind of equipment. I created the design for
Active Cords to use with these specific exercises and collaborated
with NZ Manufacturing to develop them. With these cords, I can
duplicate the movements the athlete needs. I can't do that with
dumbbells or anything else in a gym. I need equipment that
generates resistance and allows me to use it in different
Initially, athletes might use the lightest resistance levels
to train. As they grow stronger, they move through the resistances.
Some even get to the highest resistances, which are the blue and
black levels. The cords can be used in various combinations because
they easily snap on and off, allowing me to get the exact
resistance I want for an athlete. There's nothing else like this in
the market. It makes workouts quicker, more specific and more
We've been working with NZ for nearly thirty years, nearly
as long as my company has been in business. Over the years, NZ has
modified the Active Cords to accommodate my specific needs. The
products work well and stand up to serious training. Regardless of
what the resistance level is, these athletes are pushing the cords
to the limit, and the cords hold up extremely well."

We're always thrilled to see our products being
used to create positive impacts. One of our customers, Willie
Caldwell, has been doing exactly that for the past 10 years. From

individuals with physical disabilities. Check out his story
"Mobility Fitness Institute began as Mobility Fitness
Studios nearly 10 years ago. It was mostly a spinal cord injury
recovery program at the time. Since then, we've expanded to work
with clients who have Parkinson's disease or cerebral palsy as well
as amputees and stroke survivors.
Because of the wide range of resistance levels offered by
MediCordz®, I can do serious strength training with clients, even
those who have lost considerable strength from disease, illness or
injury. If we get a person who just got out of the hospital and he
or she can only lift one pound, we can begin with the resistance
level. I've seen people go from the lightest to mid-range cords in
six months and perform their exercises better.
Using the cords is more effective for clients. It stimulates
the nervous system and muscles better than just lifting weights.
The cords provide tension throughout the movement - both coming in
and going out. While they're performing that motion, they're also
I approached Maureen years ago to create the cords in
certain sizes that would be compatible with a machine I developed.
It was designed to meet the needs of any of our clients. Someone in
a wheelchair or motorized scooter can use it just as easily as
someone standing. In fact, all of our strengthening machines use
the cords that NZ created for us.
At our facility, we work one-on-one with all of our 50
clients anywhere from one to five times a week. It's rewarding to
see people using something that I built with my hands, and for that
machine to be changing their lives. Sometimes we get clients who
have already been through physical therapy and haven't gotten the
results they want. They come here and see a whole new realm of

This year, NZ will celebrate its 29th anniversary in
business. While it isn't a typical milestone anniversary, staying
in the game for nearly 30 years is a pretty significant
accomplishment. Think about it, we survived '80s hair bands,
parachute pants, side ponytails and so much more. See what Maureen
Petrasko, President and CEO of NZ Manufacturing had to say about
the company during the Q&A session below.
Q. How did NZ begin? Who founded it and what
inspired them to do it?
A. Chris Hughes, a mechanical engineer for
Boeing and a master swimmer, founded the company in 1985 after he
noticed a need for resistance products for in-water training. As
time went on, swimmers began making recommendations about existing
products and suggesting possible new products, helping the line
evolve and grow. Chris saw opportunities for the new products in
other markets and expanded the lines to include MediCordz® and
Q. When did you first become involved with NZ?
A. I had just started a consulting
business, and Chris was one of my first clients. During the period
of time that we worked together, I was offered an opportunity to
acquire the company. I decided to go for it, and it turned out to
be a great decision and an even better adventure.
Q. What was one of NZ's greatest successes?
A. Fifteen years ago, we introduced the
Drag Belt Tow Tether, and that really took us by surprise. It was a
hit from the beginning, and it's still one of our Best Sellers in
the StrechCordz® line.
Q. Have the products changed much over the
A. Adding the Safety Cord to some of our
products about 15 to 20 years ago was a significant change. This
addition provided an extra element of safety to coaches and
Q. What are NZ's plans for 2014?
A. We started moving into other markets
last year like water aerobics and water fitness, and we found that
our products fit well in those markets. This year, we'll be looking
at adding more products that can be used for applications like
water-resisted walking or running.
Q. Why have you kept the products "Made in the
A. When you're working with athletes, you
want to be sure that you have high quality products that won't fail
on them. You lose some of that control over the product when you
Q. Can you describe a time when NZ overcame a challenge
and exceeded expectations?
A. Every Olympic year, we are inundated
with orders to fill. We make it a point to never back order
anything. Since we handle the entire process from manufacturing to
shipping at our headquarters in Tallmadge, we're able to live up to
Q. What has been most rewarding for you as the owner of
A. I can't name just one thing. I've
been able to go to amazing places and meet amazing people, from
Olympians to professional football players. But, it's really
rewarding to see everyday users take our products and use them to
accomplish a dream like swimming the English Channel. It's a
privilege to be a part of that, even if it's only in a small

I have been working alongside my father for many years now,
and I know he prefers to use StrechCordz for a few different
reasons. He likes the resistance they provide and their quality.
Both of these factors need to be considered as Dr. Romanov often
trains Olympic athletes. The tubing needs to provide adequate
resistance to be effective for that level of client, and it also
needs to offer consistent resistance over a period of extended
An important indication of quality is the durability of the
product. I can't remember one ever breaking on us. We've found that
other products made from cheaper materials tend to fall apart. It
becomes a very dangerous matter when an athlete is doing resistance
exercises and a tube snaps, so durability is a key
Dr. Romanov most commonly uses the StrechCordz with Leg Straps
because of the product's versatility. When teaching athletes the
Pose Method® for running, he places the straps around their ankles
and has them stand in the Running Pose. This requires them to stand
on one leg, the support leg. The other leg is in the figure four
position alongside the support leg. The tubes pull against their
legs, making them more keenly aware of their body positioning to
prevent them from overreaching and leaving the foot behind the
body, both very common technique errors in running.
He also uses the product during technique coaching for
swimmers. He puts the leg straps around their wrists to provide
resistance while they're practicing their strokes. This subtle
resistance helps promote optimal form while reinforcing proper
motor patterns as well as building their sport-specific
StrechCordz with Leg Straps provide athletes with just the
right amount of resistance to promote a certain level of awareness
that is conducive to their success in implementing the Pose

As a company, NZ Manufacturing is always looking for new ways to
address the needs of our existing customers and to broaden the
range of customers that we serve. Recently, we re-evaluated one of
the best sellers in the StrechCordz line, the Drag Belt Tow Tether.
Seeing the great demand from swimmers, coaches and trainers for the
product, we explored ways to reach others who might benefit from a
few minor alterations to the current chutes being
The result was a larger chute (30 in. /76 cm) for use during
in-water resisted walking and running. This additional size makes
the Drag Belt Tow Tether a useful tool for those participating in
aquatic fitness and rehabilitation programs. Beyond that, the
larger chutes also provide training advantages to triathletes and
lifeguards. Both groups need to pass through water that is too
shallow for swimming, and they need to do it quickly
Just as the 8-inch (20 cm), 12-inch (30 cm) and 16-inch (40 cm)
chutes increase endurance and strength in swimmers, the 30-inch
chute improves these same areas for users as well. Training with
the additional resistance provided by the larger chute will allow
triathletes and lifeguards to get through shallow water more
quickly and with less fatigue. This one tool simultaneously
addresses timing and endurance, two vital factors for the sport and
occupation that can determine overall success.
The larger, 30-inch (76 cm) chute for the Drag Belt Tow Tether
is in the process of being developed and will be released soon.

"True Athlete Performance has created a reputation in the
athletic training industry for working efficiently with large
groups and full teams for any court or field sport. In fact, this
summer we'll be working with 18 high school football teams
throughout the northern Virginia and southern Maryland
We primarily run preseason and offseason training clinics
where we teach athletes to move efficiently by focusing on drills
that improve running technique, first-step explosiveness, change of
direction and power.
Since 2009, we've been using NZ Manufacturing's TurfCordz®
products, including the padded waist belts and 8-foot safety cords,
for athletic training. The cords are perfect for large group
settings because they can be transferred easily from one athlete to
the next. We don't want to waste a lot of time standing around
because we want to keep the athletes moving throughout the session.
Because of their transferability, we can run a great training
session for a full team with as few as six cords.
The cords offer a different approach from other training
equipment such as sleds that require pushing and pulling but don't
focus on technique. TurfCordz not only provide the specific type of
resistance needed to improve technique, but they also keep a
consistent level of resistance throughout their length. They don't
tighten up in certain spots like other cords sometimes do.
From the athletes' perspective, it's an effective training
tool. When we're working with a team, we motivate athletes by
telling them that they'll be using cords in the next session. The
athletes know the workout with the cords will crush them and
they'll be exhausted at the end, but they also like to feel
themselves getting stronger and more powerful. Other equipment we
use involves jumping over objects or developing coordination in
other ways, but the only way to build power is to work against
resistance. That's exactly what TurfCordz offer.
A few of our drills using TurfCordz include resisted
running, where one athlete, wearing the belt connected to the cord,
attempts to run as a partner walks behind and provides resistance.
Another type of drill is when both athletes wear belts and are
connected by a cord. One holds his ground, while the other runs or
shuffles out five yards and controls his movements back to the
After we complete the athletic training of a team, we often
recommend the TurfCordz products we used during the sessions to the
coaches. We can't speak highly enough about the quality of the
equipment, and we know that the athletes will benefit as they
continue to work with the TurfCordz to improve their explosiveness
and develop power."

Wayne Larsen is a fitness director and partner at One Fitness
Camp, a weight loss and fitness resort in Park City, Utah. In his
guest blog below, Wayne explains why our resistance bands are an
easy way to start or return to exercising.
"As a fitness director, the most rewarding part of my job is
seeing people build confidence as they learn how to maintain a
healthy lifestyle and lose weight. Participants at the One Fitness
Camp stay from one week to three months, and during that time,
they're introduced to many exercise options from yoga and spinning
to snowshoe hiking.
One of our classes, Band Burn, is completely centered on
working with TurfCordz and StrechCordz products. Cords offer a
simple, moderate way to begin exercising with resistance, and
people are often surprised by how many exercises can be done with
Typically, we use them in a circuit model with individuals
doing 3-5 different exercises, using controlled movements for 15-20
repetitions of each and moving quickly between them to maintain an
elevated heart rate. We've also incorporated StrechCordz Drag Belt
Tow Tether with modified, larger chutes for some aquatic resistance
exercises like in-water running or jogging, and we've used
TurfCordz Jump Belt in our boot camp program.
StrechCordz and TurfCordz are extremely versatile in terms
of workouts and intensity levels. The same product can provide very
different levels of resistance depending on foot positioning and
cord extension. They can be used for simple exercises, but we've
also found that the general public enjoys doing some athletic
drills because then they begin to feel more like athletes
Our camp can be a life-changer for many people, but in the
end, the true success of our camp is measured when they put these
practices into place at home. Resistance cords are a great option
for those who travel or can't get to the gym because they are
portable and don't require very much space to store. Getting the
most out of the cords comes from having the knowledge needed to use

"I've been a
chiropractor for 13 years, and I've used MediCordz for
nine of those years. When I found
MediCordz, I noted
that they had a very usable approach for the exercises
our patients performed, so I decided to incorporate them
into our office protocols. I believe our patients find MediCordz
easy to use, and better yet, they enjoy the results.
During a two-year residency with a group that
specialized in correcting spinal curvatures, I saw how resistance
bands could be used to do just that. We were restoring the
spine's curve for many of our patients by combining
asymmetrically applied or mirror image chiropractic
exercises and spine traction.
A light resistance had to be applied to the small intrinsic
muscles of the spine to strengthen them, while the traction
corrected misalignments more effectively than a quick
adjustment. With this approach, we typically saw a 20 to
50 percent restoration towards
normal structure in 80 percent of our patients.
Simply stated, MediCordz are very effective. They do exactly
what science says is necessary; they provide an even, symmetrical
load on the small muscles of the spine.
In 2004, I co-developed a machine called UTS (Universal
Tractioning Systems). It took the tractioning capabilities of six
machines and combined them into one. It also included an exercise
component, and I approached NZ Manufacturing, the makers of
MediCordz, because I wanted their products to be the resistance
bands for that part of the machine.
In addition to the bands in UTS, I use the MediCordz Wall
Mount Kit and Head Harness. They are an easy, convenient way to
provide essential rehabilitation to patients. They're cost
effective and take up minimal space. These last two points are
important for patients, who purchase their own kits to use at

"Warming up for a triathlon can be problematic. Competitors
want to prepare their bodies for the strain they're about to

potential as an athlete, and that's why I like them for other
Some people might look at the price of a StrechCordz product
and think 'Why would I pay $30 for elastic resistance tubing?' I
would encourage those individuals to buy a StrechCordz product.
Used diligently, they will improve efficiency, speed, power,
strength and endurance for any user. It's a small price to pay for
a big personal improvement to the athlete in all of us.
A word to the wise, though: StrechCordz are made for
professional athletes and provide much more resistance than you
might imagine. When you select a resistance level, err on the side
of caution. You can always increase reps if need be, but a tube
that's stronger than you won't do much good."
Andy describes one of his most reliable exercises with
"I use it for a standard free style smooth stroke. I attach
the StrechCordz to a pole, fence post or backstroke flagpole,
making sure the attachment is higher than my head. Then I bend at
the waist until my upper body is in a horizontal position, and I
practice my free style swimming with fingertips pointed down,
emphasizing high elbow all the way through the top of the stroke
