Presenting the Range3D multi-gym
Range3D’s flexibility training multi-gym has been developed specially to match state-of-the-art cardiovascular and strength equipment. The design includes every feature needed to produce results, so that the exercises help optimise musculoskeletal function.
The effective stretching action is based on the body being supported and stabilised in the right position for each exercise. The Range3D multi-gym guides the legs in the three anatomical planes, providing a complete stretching routine for the hip and thigh muscles. All movements are safely controlled and the range of motion is measured electronically to give accurate feedback.
By doing almost everything for the user, the Range3D multi-gym guarantees correct form. The beginner is immediately able to stretch properly, while those with a regular stretching regimen can transfer exercises and notice the difference.
The Range3D multi-gym represents a step change in flexibility training equipment, with benefits for sporting performance and physical well-being.
User is comfortable and relaxed, with the body fully supported and stable.
Stretch is applied effectively in the correct exercise position.
Range of motion measurement compares left and right legs and quantifies improvement.
Movements are restricted to anatomical planes and the user has precise control.
The standardised, reproducible, measurable regimen helps with conditioning and monitoring.
Ideally suited to the process, from early stages through to restoration of normal function.
How it works
The head rest and leg supports can be adjusted to the user’s height. A sliding ankle support accommodates variations in lower leg length and cups the heel to prevent the foot moving. Access is from a footplate at the front, allowing the user to sit within the leg supports, which are bent at the knee. The leg straps are fastened first and the waist grips are tightened once the user is lying back.
The body is now supported and stabilised, ensuring the stretching action occurs at the hip joint and is not transmitted to the pelvis and lumbar spine. The user remains in position throughout and is able to go straight from one exercise to the next.
Two handles on either side provide leverage for every exercise position. The leg supports are easily raised because of the gearing, and lowering is braked by a damper.
All the exercises start from the anatomical neutral and are shown on an instruction placard. The user switches on a ratchet before moving a leg support, and the 2° or 3° ratcheting intervals provide fine control when the stretching limit is reached. This position will be held by the ratchet for as long as required. The leg can then be either moved further into the stretch or returned to neutral once the ratchet is switched off.
The leg supports rotate about axes which coincide with the hip joint, enabling angle sensors to accurately measure the true range of motion. Their output is displayed digitally and the reading may be stored using a “hold” function. A timer on the console saves the user from having to count the duration of the stretch.
Professional stretching equipment for the hip joint
The opposite leg is kept extended to prevent the pelvis tilting posteriorly, so the ideal stretching position is maintained.
In the same position as the hamstrings exercise, the knee is flexed and brought to the chest.
The body is in a fully extended position with the pelvis stabilised.
The opposite leg is flexed at hip and knee to enable adduction in the frontal plane. This exercise is particularly beneficial for iliotibial band syndrome.
The leg is placed in the standard orthopaedic position to stretch the rotator muscles.
The lateral rotators include the piriformis muscle which, if shortened, can cause sciatic nerve pain.
One-joint hip flexors: The opposite leg is fully flexed to tilt the pelvis posteriorly and bring the hip into extension. Gravity provides a downwards stretching force, which can be increased by using one of the handles.
Two-joint hip flexors: The exercise is repeated with the knee flexed at 90°.
Uses the method of passive static stretching
Suitable for any level of flexibility
All hip muscle groups can be isolated on one piece of equipment
No adjustments are needed between exercises
Makes flexibility training straightforward and rewarding
Range3D multi-gym in sport, active health and rehabilitation
Group conditioning and monitoring
The athletes will all be able to perform the same stretching exercises in exactly the same way, and the range of motion feedback helps identify inadequate hip mobility and muscle imbalance.
The hip rotator muscles are often overlooked when stretching, but are important for sports requiring a great degree of flexibility through the shoulders, spine and hips.
The specifications have been designed to exceed the normal ranges of motion, thereby catering for special groups who need to be highly flexible.
Foundation for fitness
A fully mobile hip means that the forces on the joint surfaces should be distributed evenly, and enables the dynamic exercises which promote blood supply to the joint. As the hip is the link between the lower body and the trunk, preventing muscles which cross the joint from shortening will aid correct posture and movement.
The range of motion values allow the user to see where flexibility may have to be improved. This is especially helpful for those beginning a new activity, and who suffer problems caused by inflexibility of the hip and thigh muscles. Regular exercisers can keep track of these values, just like any other fitness-related metric.
After injury or surgery
The exercises start from neutral, enabling progression even when the range of motion is significantly reduced. A complete stretching routine for the hip muscle groups is available such that the patient doesn’t have to transfer between equipment. Where appropriate the therapist can switch off the ratchets to employ other rehabilitation techniques, such as PNF stretching and assisted/active range of motion exercises.
The leg supports move in the planes used for a standard physical examination of the hip. Accurate range of motion measurement helps with monitoring progress and can confirm that normal mobility has been restored.
