Barrier-free training with the Duplex shoulder trainer

The wheelchair-friendly version of the shoulder trainer is an exercise device for outdoor use that has been developed on the basis of sports and training science and is ergonomically designed on one side for use by wheelchair and walking frame users.

Alone or in pairs, the apparatus-supported movement control guarantees relaxed shoulder training with a soothing massage effect on the palms of the hands.

Ideal installation locations for the playfit® Duplex Taiji Massage Machine are those where the planning specifications stipulate that the exercise programme must be barrier-free:

  • Municipal parks
  • Residential neighbourhoods
  • health resorts
  • Rehabilitation clinics
  • Retirement homes
  • Hotel complexes and leisure parks

For whom is the playfit® Duplex Taiji Massage Machine suitable?

The Duplex shoulder trainer for outdoor use is suitable for people of all ages with or without training experience.

This piece of sports equipment is very interesting for wheelchair users or people who use a walking frame to get around. The heights of the massage discs on the lower user side are designed so that ergonomically adapted training is possible when sitting in a wheelchair or on a walking frame.

Athletes also use this fitness equipment: the further away you stand from the rotating discs, the more you can get into a push-up position – a real challenge on rotating discs. On the lower training side, the exercise becomes even more strenuous as more weight presses on the shoulder muscles. The lighter exercises on the duplex shoulder trainer (outdoor) are also suitable for the cool-down phase.

Training effect & training goals

The circular movement of the arms improves mobility in the shoulder girdle and trains the fine motor skills of the arms and hands.

Light pressure on the massage discs massages the palms of the hands. The exercise option of varying the rotating movement in different directions trains coordination and balance.

Alternative training effect and Far Eastern approach

This shoulder training programme focuses on acupressure and movement. The massage nubs on the rotating discs massage all the acupuncture points on the palms of the hands. The round, circular movements of the arms and shoulders primarily stimulate the lung and large intestine meridians, but also the cardiovascular system and the triple warmer.

In summary, vitality and metabolism are increased, many blockages are released, breathing becomes calmer and can unfold more freely. Mind and soul relax in the flowing movement.

Advantages of the outdoor shoulder trainer

  • User-friendliness for wheelchair and walking frame users
  • Wide range of applications: sporty and sedentary people as well as old and young people

Instruction for Use

Stand in front of the two massage discs with a slight lunge and slightly bent knees. Place one hand on the right disc and one on the left disc. Your elbows should be pointing downwards

Rotate the discs with light pressure in the same or opposite direction. Let your body swing with the discs. Slide your hands over the nubs of the massage discs and feel the pleasant massage effect through your hand movements.

Increase your distance from the massage discs by taking small steps backwards. Now perform the circular movements as described above and feel the tension throughout your body.

Special exercises

Turn both discs in a circle in the same direction. Slightly bend your knees when your hands turn downwards and straighten your body again when your hands turn upwards.

Variation 2
‘Circular movement with one arm’

Stand sideways at right angles to a massage disc and turn the disc backwards in a circle with one hand. Change the direction and side of the movement.

Exercise for as long as you enjoy it and feel good. For a long-lasting training effect, we recommend a training duration of 5 – 10 minutes.
