“Core stability training should receive some attention in the training programs of all athletes.  The ability to stabilize the core region allows for efficient transfer of force between links in the kinetic chain.  Thus, from a scientific perspective, core stability in athletes should be addressed with varying methods, depending on the phase of training and the health status of the athlete.”  Core Stability for Athletes, Jeffrey M. Willardson, PhD, CSCS, 2008

 What are Pelleres?

Pelleres are a weighted arm sleeves that wrap around the forearm and are biomechanically designed to increase the power and strength of an athlete when used during exercise.  By adding weight to the forearms Pelleres strengthens not only the muscular structure of the upper body but engages the core muscles of the abdomen which improves the capability of large muscle groups like the quads, glutes and hamstrings.  This in turn creates greater power for an athlete and enhances overall performance.

Pelleres harness the well-known and highly regarded principles of overload, resistance, and functional training to strengthen the core muscles.  Pelleres uses the principles of super compensation and biomechanics to improve your output.  While all the laws of training are important, the principle of overload is the foundation of every fitness regimen.

Pelleres come in four (4) different weights and colours and are purchased in pairs (left and right).  The amount of weight applied is critical to performance of the device.  If too much weight is applied then other muscles are recruited and the abdominal muscles are not activated in isolation.

  1. Pelleres 2.0 – 200grams, blue
  2. Pelleres 3.5 – 350grams, green
  3. Pelleres 5.0 – 500grams, yellow
  4. Pelleres 7.5 – 750grams, red

What Weight Do I Choose

The general “rule of thumb” for selecting which Pelleres to use is as follows:
1.  Fast movement = light Pelleres e.g. Pelleres 2.0 (200 grams, blue) or Pelleres 3.5 (350 grams, green)
2.  Slow movement = heavy Pelleres e.g. Pelleres 5.0 (500 grams, yellow) or Pelleres 7.5 (750 grams, red)

AND for users under 15 years highly recommended use only Pelleres 2.0 and Pelleres 3.5.


Pelleres 2.0 & Pelleres 3.5 – running, agility drills, cardio fitness, ball games, throwing, catching, functional exercise, med to high intensity, boxing, fitness games, jumping.

Pelleres 5.0 & Pelleres 7.5 – walking, stretching, low to med intensity, slow movement exercise, technical development, rehabilitation.

How & Why Pelleres Work

Pelleres activate abdominal muscles in isolation.  By overloading the forearms with weight, stress is created and the body is forced to adapt by engaging the core muscles of the abdomen.  This relationship between overloading the forearms vs abdominal muscles activation is the biomechanical principle underlying Pelleres success.  The “Pelleres principal” was observed by track and field coach and ex-professional international sports representative (rugby) Mepi Faoagali in 2008-09 who later developed the Pelleres device (2010) and training system (2014).

Weight is specifically positioned on a section of the body – in this case the forearm – which forces specific muscles to activate in isolation.  Abdominal muscles called rectus abdominus, transverse abdominus, and the internal and external obliques are all forced to work harder when wearing the device.

As the body adapts the initial response is fatigue, then recovery.  This increased recovery and adaptation stimulate super compensation which takes you to a higher level of fitness, allowing you to become stronger and more powerful.

Pelleres also harness functional training techniques which involve weight bearing activities targeted at the core.  Unlike weight machines which target and isolate specific muscles and therefore restrict the body to a single plane of motion, Pelleres allow an athlete to perform their usual task (ie. running, kicking, catching, throwing, bowling, batting, etc.) without restricting their range of movement.  By weighting the forearms the body is less prone to injury than if the weighted device was placed in the hand or at a distance from the body causing stress to the shoulder, neck and torso.

Pelleres are classified as FUNCTIONAL STRENGTH TRAINING DEVICES.  Functional movements are movements based on real-world situational biomechanics. They usually involve multi-planar, multi-joint movements which place demand on the body’s core musculature and innervation.

Pelleres are unique for three main reasons:

  1. The position of the weights, along your forearm, successfully targets your core stabilizer and major muscle groups. Unlike “wrist weights”, Pelleres™ evenly distributes the weight along the ulna (forearm) bone – this is why they are so effective. Our forearm is heavier and our abdominal and core muscles are being forced to work harder.
  2. Range of weight. Pelleres™ come in four weights which covers the weight range (0-1kg) for functional movement. To successfully strengthen core muscles normal movement patterns must be maintained. The relative weight (200g, 350g, 500g, &750g) of Pelleres ensures integrity of movement during activity.  Weights heavier than 1kg force bigger muscles to take control over the movement, lessening the effectiveness of our abdominal and core muscles.
  3. The weights are anchored to your forearm which allows for a natural, unimpeded, and dynamic actions. Your wrists and hands are free which allows normal functional movements. This is particularly important as core strengthening occurs in a functional environment. You can hold apparatus and replicate “real” game and event situations.

The Core

The human body is amazing but it is also complex.  The body is a chain of mobile joints that must be controlled to support with efficiency.  If not the muscles work overtime, become fatigued, and risk injury.  Trained stability muscles keep the body in line, working efficiently and improves performance, reduces the risk of injury and reduces rehabilitation time.

The cornerstone of all athletic movements are the abdominal and core muscles. An athlete can train to increase strength, power, speed, agility, and quickness but if the core muscles are weak, the athlete will not reap the full benefits of this hard work.

The core muscles transfer the power developed in the hips and legs into the arms and vice versa. A strong core will also help to protect the back from potential injuries associated with sport participation.

Not only is overall core strength important, just as valuable is core muscle coordination. Exercises that place the body in an unbalanced position help to develop the strength and coordination needed for the core muscles to function properly.

Current research emphatically confirms the importance of regular moderate physical activity for public health. Authorities that recognise and support these findings include the World Health Organisation, the US Surgeon General, the Australian Health Ministers Advisory Council, the American College of Sports Medicine, and the American Heart Association.

Did you know?

  • More than half of our weight is above our hips, and our head weighs more than 6kg.  Yet all control must originate where we contact the world, through our feet.
  • An average adult arm weighs approximately 3.2kgs and is normally between 40cms and 50cms long.
  • Of the 206 bones in the average human adult’s body, 106 are in the hands and feet. (54 in the hands and 52 in the feet) and relative to size the strongest muscle in the human body is the tongue.
  • Most skeletal muscles are ‘movement muscles’, powerful but prone to fatigue. The ‘stability muscles’ are vital muscles for controlling the joints of our bodies. Properly trained, ‘stability muscles’ enable us to be more effective, for longer.
