Revfin fitness

Run faster, improve your atletic conditioning workouts

It's very hard thinking to change your training plan. Especially, it's very odd running in the pool instead of employing usual training in the dry land track. Who challenged that, overcame this psychological constrain and faced himself to test the effectiveness of this training method in the water, has certainly been satisfied and amazed at the same time. Athletic training in the water is, due to water nature, very severe but indeed it draws you towards a special physical shape that will improve you sport performance.

Increase your Resistance with REVFIN

Ready to take your workout to the next level? The variety of cardiovascular exercise and muscles strengthening you can apply with REVFIN will challenge all fitness levels. Swimming skill is not necessary, but you must be comfortable in water.

REVFIN makes the case in athletic conditioning exercises

You fit REVFIN like a fin but you get more. Experience the resistance at your legs due to the drag. Try the front and back kick with REVFIN on, move your legs when sitting on the poolside, move your legs staying afloat in horizontal position.

Atheltic conditioning and aqua-fitness by REVFIN

Aqua-Fitness (Pool Aerobics) continues to grow in popularity as a results-based alternative to traditional exercises. It offers low-impact toning and cardio workouts, and is appropriate for people of all ages and abilities. No matter your swimming ability, all you need is some water to get started. Fit REVFIN and you will experience in muscles strengthening:

  • Hip Flexors, Hamstrings, Buttock
  • Soleus, Iliacus, Psoas, Quads, Tibialis


WHY REVFIN in athletic conditioning?

You get a tool that adds a new dimension in the water exercises, just taking advantages of the drag effect both in stretching and in force exercises. Kick vertical and horizontal position, and sitting on poolside as well. Water offers four times the resistance of air. So, while some of these moves would present little challenge on land, they do in the water. Water can also add some instability, meaning your core gets a different, and arguably better, workout.

  • Fits like a Fin and applies drag in the Water
  • Allows a wide range of kicking exercises
  • Allows customization of drag effect

REVFIN has been designed by swimmers and bio-engineers

With its comfortable fit of natural rubber, REVFIN is easily worn. Due to its shape REVFIN applies the drag action when moving either the legs or the whole body through the water. Then, REVFIN efficiently stretches your rachis and leg/foot muscles. No other equipment in the aqua fitness landscape is able to play such a rule in a so simply and effective way. Customization of the drag effect is one of the key points of the REVFIN application in aqua based fitness.


For runners and all sportsmen

Revfin is the pool training tool ideal for people who want to use the water's resistance, hydrostatic pressure and buoyancy to increase their muscle power, endurance, and flexibility. The basis of contemporary training was founded several years ago and is more widespread nowadays because water training enable to maintain and improve performances. Soon many athletes discovered the power water workouts. Among others: Usain Bolt, Florence Griffith, Jessica Ennis, Wilt Chamberlain, John Lloyd, Mike Powell, Valerie Brisco, Luc Robetaille, Bo Jackson. Although a new option in sport training, water training is gaining popularity as coaches and fitness professionals learn more about Its effectiveness.

Revfin has been designed to take full advantage from water resistance. By means of its adjustable blade it increases drag to the feet and body movements. By its peculiar shape, and customization features, it allows to work on several training programs. By Revfin you can create your complete work overload that is so stressful to provide muscular adaptation but not severe enough to cause injury or impair performance through over-training.

The main involved muscles when you perform this drill by REVFIN

Hip Flexors
1. Iliacus
2. Psoas
3. The rectus femoris
4. Abdominals


The initial knee lift phase is propelled by the muscles at the hips. The Hip Flexors are the iliacus and psoas muscles. Their contraction commences the movement of the thigh up towards the abdomen. To perform this exercise with Revfin, lift one knee as high as possible while pointing the foot and straightening the opposite leg. Perform some fast or slow reps depending on the level of water resistance intensity you like and according to your current level of fitness. Running drills also strengthen your psoas muscles which act as levers during all types of running. The key point for a strong psoas, and proper knee lift in sports, is training by lifting your knee up to 90 degrees or higher. Being strong in 90 degrees-plus of hip flexion also helps ensure optimal femur stability control.

The main involved muscles when you perform this drill by REVFIN

1. Semitendinosus
2. Semimembranosus
3. Biceps femoris (long/short head)
4. Gastrocnemius
5. Soleus


To perform this exercise by Revfin, stand facing the pool wall so you can hold on for balance. Tighten the back top of your right thigh, flex your foot and lift your right leg straight out to the back. Lift as high as you can without tipping forward or arching your low back. Then, lower slowly down.
Leg curls of all kinds are excellent exercises for the hamstrings. They are unique, because unlike their counter movements, the leg extension, they provide no shear forces to the knee, and provide a direct component of hamstring training that cannot be obtained any other way. Leg curls by themselves cannot develop the fullest strength potential of the hamstrings, but they are both a great beginning movement, and are effective in the prevention of injury from hamstring pulls during running and sprinting.

The main involved muscles when you perform this drill by REVFIN

1. Rectus femoris
2. Vastus medialis
3. Vastus lateralis
4. Vastus intermedius

5. Ankle muscles


Rotate Revfin’s blade and fit it Extended, stand sitting on the edge of the pool with your legs in the water. Keep your upper body straight and your back flat against the floor. Exhale and lift both of your legs until they are completely extended. Slowly lower your legs back to the starting position. If desired, lift one leg at a time.
Leg extension is a open chain exercise. In a study comparing open versus closed chain training amongst athletes undergoing, it was concluded that subjects engaging in open chain quadriceps strengthening were significantly more likely to return to their sports at pre-injury levels than those employing closed chain.
Work with Revfin to strengthen ankle muscles: sit and slowly straighten your knee. While holding the knee straight bend the ankle and point the toes. Then, reverse to point them toward the ceiling. Revfin with Extended blade increases the drag to your ankle movements and helps you to reach higher ankle flexibility.

The main involved muscles when you perform this drill by REVFIN

1. Abdominal
2. Trunk
3. Torso
4. Buttocks (Hip extensors)


Stand sitting on the edge of the pool with your legs in the water. Keep your upper body tilted and supported by your elbows against the floor. Slide your body into the water without remove your elbows from their position, lift your knees as close to your chest as possible, raise the foot as much as possible, and pull the heel close to the buttocks at the end of each cycle. Push explosive the water! The heel mounted Revfin’s blade adds drag to your movements and strengths your buttocks too.
The importance of the runner’s core strength
The muscles of the trunk and torso act to stabilize the spine, pelvis and shoulder girdle. From this solid, balanced base the limbs can be moved powerfully and under control. In fact before rapid movements of the extremities can take place, the central nervous system stabilizes the spine in anticipation. The rate at which the core muscles stabilize the spine may have a direct effect on the power of limb movement. Core strength training differs from many traditional weight training routines by working both the lower back and abdominal in unison. The same is true for the upper and lower body. All athletic movements incorporate the core in some way. Very few muscle groups are isolated. Instead the whole body works as a unit and core strength training endeavors to replicate this.

Hip Flexors
1. Iliacus
2. Psoas
3. The rectus femoris
4. Abdominals
5. Buttocks


In a face down position on the pool wall, balance on elbows or your hands lift the knee explosive. This movement simulates the start from the blocks and is a very effective workout for hip flexors. Revfin’s blade position adds the drag load in axis with your back increasing the hip flexors effectiveness.
Face down position on the pool wall, balance on elbows while pushing back explosive the foot. While extending the hip by a semicircular movement, make sure of moving both joints into their full range of work. This exercise, very similar to quadruped hip extension, step-ups and lunges, generates significantly more buttocks activation than squats. Performing this exercise in the water by Revfin leads to two advantages:
- You get additional drag to your movements to simulate blocks push out
- Your legs weight is balanced by the water, then the back muscles are unloaded as well.

The main involved muscles when you perform this drill by REVFIN

1. The rectus femoris
2. The vastus medialis
3. The vastus lateralis
4. The vastus intermedius
5. Hamstrings
6. Hip extensor


In these exercises, the athlete coordinates arms and legs as they would to cross country ski. The body is vertically aligned and legs and arms are kept straight. The basic motion is to scissor the legs forward and backward from the hip leading with the toes while the arms pull through the water. Actually, by Revfin your whole body do not quite move forward due to the low friction of the blade with the pool floor. This helps in performing the drill even when few pool slots are available.
Water cross country skiing can help improve running economy (the amount of oxygen used during a run). Because the hips, quadriceps, core and upper body are all involved in performing this workout, it helps in developing the weaker quadriceps without impact. One of the greatest benefits that comes from this activity is the high calorie expenditure.

The main involved muscles when you perform this drill by REVFIN

1. Forearm muscles
2. Latissimus dorsi
3. Pectoral
4. Biceps and Triceps
5. Hamstrings and quads
6. Hip extensors
7. Thoracolumbar fascia


Revfin shows its highest potential while swimming freestyle. Additional drag from your feet will slow down your speed. Thus, you have to swim at highest power to move in the water. This exercise is really vital for runners and footballers because of its spinal and lumbar muscles eccentric action that prevents back injury.
The full-body nature of swimming requires wholly different movement patterns, giving a runner the opportunity to work some of those often forgotten muscle groups. Although the theory of specificity suggests that a runner must run to improve, many of our bodies aren’t built to achieve optimal fitness through running alone. The muscle imbalances that occur over many miles only worsen with each step. Swimming introduces new ranges of motion and strengthens muscle groups that have been neglected, helping a runner avoid classic overcompensation injuries.

8. Abdominals


Fit Revfin Classic version and swim backstroke. The blade stiffness decreases the magnitude of flapping and the kick becomes a good exercise for leg muscles, abdominals and glutes. Adding backstroke to your workouts has several benefits that will help you in and out of the pool. Aside from being a great total-body exercise and calorie-burner, backstroke can be the perfect antidote to rounded shoulders or even back pain.
If you're a runner, swimming is a low-impact way to cross train between runs. Backstroke kicks engage the muscles in your legs and glutes for a complete lower-body workout; further challenged by the resistance of the water.

When you're not rocking it out in the weight room, use backstroke as a way to straighten your arms and shoulders. Once your fingers enter the water to begin your catch, your biceps must bend against the resistance of the water to finish each stroke. Although your biceps and lats are in the greatest demand during the catch, your triceps and lats will benefit as well.

The main involved muscles when you perform this drill by REVFIN
1. Calves
2. Tibialis and soleus
3. Hip extensors
4. Hamstrings and quads
5. Rectus femoris
6. Vastus medialis
7. Vastus lateralis
8. Vastus intermedius
9. Tibialis Anterior


Fit Revfin Extended in order to perform this exercise correctly. Start swimming backstroke normally but do not keep straight legs. Instead, move your legs as cycling. As you bend heel near to the buttocks rotate the toes to the ceiling preparing to kick the water away.
You can be helped by a couple of pads to be kept off your elbows. This exercise can be performed by Revfin only. It is not possible to do that by a regular fin because of the not suitable blade stiffness. This is a great workout for buttocks, quads and calves. Try how excellent and unique is the degree of stess of the Tibialis Anterior.

Leg Back and Forth
1. Hip extensors
2. Hamstrings and quads
3. The rectus femoris
4. The vastus medialis


Raise the your knee up towards the hip while moving your arms to keep the body balanced. Extend your foot forth and retract it back to the staring position with the heel toward the buttocks. Then, move knee backwards as much as possible extending the foot back as well.
Playing this drill into the water by Revfin allows your hands to keep the body balanced. Then, by the extra drag together with the three water aerobics topics: weightless, water massage and water resistance to movements give the effectiveness to the exercise.

Ankle Jump
1. Peroneus
2. Gastrocnemius
3. Tibialis Anterior
4. Soleus


Fit Revfin jumping mode. You have to change the blade and insert the new one customized by neoprene thick fabric in the front side. Jump into the water either by the two feet aside or one at a time. Keep the vertical movement aligned and gradually increase the jump frequency and amplitude. Pivot the weight by using the toes and lift the back of your feet off. The two muscles that make up the calf are the gastrocnemius muscle, which gives the calf its rounded shape and the soleus, which is the flatter, longer muscle running underneath the gastrocnemius and lower down your leg. Both of them are involved in the wide range movement obtained by the water floating effect. Besides, the whole ankle ligaments set is strained.
This is the great advantage from this drill by Revfin: regardless your weight the water amplifies and slowes down the movements allowing gradual and customized muscles and tendons stress.


REVFIN drag customization

Thanks to its design REVFIN can be customized to a dedicated configuration as desired. This is possible because of the smart fit. In the bottom part of the shoe a sliding guide can be tightly inserted. The sliding guide in turn can be linked to the drag devices of any form and consistency by screws.

REVFIN Jumping mode

Turn your REVFIN into JUMP MODE.
Just purchase the paddle with thick NEOPRENE fabric in the front side. This gives to REVFIN the proper stiffness to enjoy high jumps in vertical position into the water by the most natural and effective way.
