A high-tech gym machine for stretching

Range3D’s flexibility training multi-gym has been designed to match state-of-the-art cardiovascular and strength equipment. It incorporates 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 a position that isolates the muscle group. Because the Range3D multi-gym guides the legs in each anatomical plane, it provides a complete flexibility training 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 ensures 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 is 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.

Exercise technique

Stretch is applied correctly for each muscle group in the routine.


Range of motion measurement compares left and right legs and quantifies improvement.


Movements are restricted to anatomical planes and the user has precise control.

Athletic groups

The standardised, reproducible, measurable regimen assists conditioning and monitoring.


Ideally suited to the process, from early stages through to restoration of normal function.

How the Range3D multi-gym works


Head rest and leg supports can be adjusted to user’s height.

Sliding ankle support allows for variations in lower leg length and cups heel to prevent foot moving.

User stands on footplate and sits within the leg supports, which are initially bent at the knee.

Leg straps and waist grips are tightened to keep the body correctly aligned.


Stretching action occurs at the hip joint and is not transmitted to the pelvis and lumbar spine.

User remains in position throughout and is able to go from one exercise to the next without any adjustments.

Handles for horizontal and vertical movement provide leverage in every exercise position.

Leg supports are easily raised because of gearing, and safely lowered with braking damper.

Flexibility training equipment for the hip joint
Measurement of hip joint range of motion


All exercises start from the anatomical neutral and are shown on an instruction placard.

Before moving a leg support, user switches ratchet on, with small intervals to give fine control.

Stretching position is held by the ratchet for as long as required.

Leg may then be either moved further into the stretch or returned to neutral.


Leg supports rotate about axes designed to coincide with the hip joint.

Angle sensors accurately measure the true range of motion, which is displayed digitally.

Legs are moved separately, so values for left and right can be retained and compared.

Timer function saves user from having to count for the stretching duration.

Stretching exercises

– aided by innovative engineering

Flexibility training equipment for the hamstrings

The opposite leg is kept fully extended to maintain the ideal stretching position.

Flexibility training equipment for the hip extensors and flexors

In the same position as the hamstrings exercise, the knee is flexed and brought to the chest.

Flexibility training equipment for the adductors

The body is in a fully extended position with the pelvis stabilised.

Flexibility training equipment for the abductors

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.

Flexibility training equipment for the medial rotators

The leg is placed in the standard orthopaedic position to stretch the hip rotator muscles.

Flexibility training equipment for the lateral rotators

The lateral rotators include the piriformis muscle which, if shortened, can cause sciatic nerve pain.

Flexibility training equipment for the hip extensors and flexors

One-joint hip flexors: The opposite leg is fully flexed to tilt the pelvis posteriorly and bring the hip into extension. Gravity provides the stretching tension, which can be increased by applying downward pressure with the handle.
Two-joint hip flexors: The exercise is repeated with both knees flexed at 90°.

Commercial grade construction

Complements cardiovascular and strength machines to expand fitness provision

Suitable for recreational to elite standard

Simplifies flexibility training with straightforward routine

Requires only basic maintenance

Advantages of the Range3D multi-gym


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. Stretching also promotes recovery, allowing muscles to regain normal resting length.

Special demands

Certain sports require a higher level of flexibility, either in a particular muscle group such as the hip rotators, or just more generally. The specifications have been designed to exceed the normal ranges of motion, so that this can be achieved. The stability and control especially assist the user with developmental stretching.


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.

Staying active

The range of motion values allow the user to see where flexibility may have to be improved. This is particularly 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, like any other fitness-related metric.


After injury or surgery

Passive static stretching is appropriate, and may be controlled by either therapist or patient. The exercises for hip muscle groups are all available on the same piece of equipment. By switching the ratchets off, the therapist can also perform PNF stretching and assisted/active range of motion exercises. In every case, the patient is in a supported and stabilised position.

Functional assessment

The leg supports move in the planes used for a standard physical examination of the hip, making it easy to assess the patient. Accurate range of motion measurement helps with monitoring progress and indicates when normal mobility has been restored.
