Zoomers Technology
Former Stanford All American Swimmer and Water Polo Player, Dr. Marty Hull, first designed the Zoomers swim fins in 1992.
FINIS partnered with Dr. Hall in 2002, and later co-developed the Zoomers Z2 training fin.
What are Zoomers?
Zoomers are unique swim fins that utilize patented short-blade technology to promote a shorter, faster kick. They are
designed to provide the ideal amount of propulsion for perfecting the swimming kick and stroke, allowing for better
form over longer periods of time.
Because they have a smaller blade than traditional swimming fins, Zoomers make the legs work harder without overloading
the muscles. They help you avoid burnout and sustain an optimum workout level over a longer period.
Zoomers fins allow you to practice swimming at or above race-level speeds without being rested or shaved. For each
speed in the water, there is a size of kick that works best. The kick creates propulsion that moves you forward, but each
time the legs separate in the flutter kick, drag is created which slows the swimmer down. At higher speeds, the drag
created can potentially cancel out the extra effort put in.
A smaller kick creates less drag, but also less propulsion. Zoomers are designed to help practice and perfect this
smaller kick by providing just enough extra propulsion while avoiding additional drag.
"I've been training with Zoomers fins for years. They've helped me workout very hard and
become the fastest in the world. Whether you are a beginning swimmer, fitness swimmer or record holder, Zoomers will
improve your swimming."
- Jeff Rouse, 1992/1996 Olympic Gold Medalist
Red vs. Blue Zoomers
Zoomers come in two models. Red for advanced competitive swimmers with a developed, strong kick, and blue for swimmers
who are looking for a strength-training workout.
Why do I need the Zoomers?
To get a great workout, you must exercise a large percentage of the body's muscle mass at a reasonably high level of
intensity for a long period of time. Due to the nature of swimming, swimmers often fall below this optimum level of
workout, primarily because of the difficulty in sustaining an efficient kick. Zoomers make the legs work harder, but
the smaller blade will not overload the leg muscles. Therefore a high level of intensity can be maintained for a longer
period of time. The additional propulsion allows the arms to cycle faster, providing the opportunity to breathe more and
increase the oxygen intake needed to sustain the effort of the leg muscles.
We do not race at slow speeds, yet most workouts are done at sub-race speeds. Therefore, we spend much of our time
practicing techniques for slower swimming - a different size kick, speed, arm turnover rate, body position, and arm entry
angle. Zoomers make it possible to practice correct techniques at race pace speeds for extended periods of time.
Training at or above race speeds with Zoomers can also improve neuromuscular coordination and reduce upper-body stress
associated with typical sprint training. The core of your workout is enhanced, allowing you to become a better swimmer with
a stronger, faster kick.

How do I get started with Zoomers?
The first thing to do is get some Zoomers fins and go swimming. Zoomers fins will let you swim faster, work out harder, and
have better body control in the water. Start using Zoomers fins when swimming a normal set. When you begin swimming with
Zoomers fins, use a gentle kick and gradually increase intensity to see what level you can sustain. The most effective way
to increase the intensity of your workout is to use interval training. Rather than swimming continuously for two hours,
divide the workout into shorter distances. Swim each distance with more intensity and then rest in between each swim.
If you experience tiredness after the first few laps, you need to pull back into a pace that will allow longer workouts. To
learn what type of kick works best for your body type and speed, start with the calibration drill. This exercise works
best when you are completely submerged, so do this in the deep end of the pool.
Try these introductory drills with Zoomers:
- Calibration Drill - Push off the wall about 3 feet under water, holding your arms out in front of you
with your hands together to streamline the body. Use a butterfly kick or a flutter kick. Keep your toes pointed and your
knees fairly straight. Just push the fins up and down. Start with a large kick, and gradually make the kick smaller and
faster. You should feel yourself going faster as the kick gets smaller and faster. Experiment with limits. When you are
going very fast, abruptly change to a large kick. You will feel a sudden and significant increase in drag, and you'll
slow down.
- Shooters Drill - Push off the wall on your back about three to four feet under water. Kick 25 yards as
fast as you can. Rest a short time either at the end of the pool or by swimming easily. Push off the wall and do another
"shooter." Repeat this sequence 15 to 20 times, once per week. Each week you will learn more about streamlining
and develop easy speed under water.
Quick Tips:
- Zoomers can provide for a strenuous workout. Warm-up with some dry-land, ankle stretching exercises.
- Blue fins are for swimmers who don't swim every day, but are looking for a strength-training workout.
- Red fins for advanced competitive swimmers with a developed, strong kick.
- Try to gradually increase the intensity of your swim sets with Zoomers over a few weeks. If you are able to maintain a higher rate for longer, you are getting in a great conditioning workout.
- Using fins and paddles together provides a really great workout and introduces some variety. Swim some of your workout with fins and paddles, some with paddles, some with fins and some with nothing at all (except swim suit and goggles).
