PlyoDyne does not guide the body through one pre-programmed path. It provides defined mechanical conditions within which the user creates the movement.
The flexible joint allows the straight shaft to tilt in multiple directions.
02
Shaft rotation
A bearing directly above the flexible joint allows the complete shaft to rotate around its axis.
03
Handle travel
The handle slides freely along the straight shaft.
Three coordinated movement possibilities
This illustration shows the three movement possibilities combined in one PlyoDyne system.
Blue — SlideThe handle moves axially along the shaft.
Green — RotateThe handle and shaft rotate together as one keyed assembly.
Red — TiltThe shaft tilts in multiple directions through the flexible joint.
The available tilt can be left free, limited or supported by adjusting the Range Control Ring.
THE DEFINING RELATIONSHIP
Free to slide. Keyed to rotate.
The groove mechanically keys the handle to the shaft. The handle can travel along the shaft, but it cannot rotate independently around it.
When the bearing-mounted shaft rotates, the handle rotates with it as one coupled assembly. The straight 25 mm shaft passes through the centre of the handle; there is no bend or offset in the shaft path.
VISUAL FOCUS
Follow the hand. Add another training dimension.
Looking forward towards the equipment provides a stable visual reference. Once the movement is controlled, following the travelling hand with the eyes allows the head and upper body to turn naturally with the movement.
FOUNDATION
Look forward
Use a forward gaze during familiarisation, higher-load work or whenever balance and movement control need a stable reference.
PROGRESSION
Follow the travelling hand
Following the hand adds visual coordination and increases the involvement of the shoulders, thoracic region, upper trunk and upper core.
Begin this variation slowly with a low load. Return the gaze forward if balance decreases or dizziness, neck discomfort or loss of movement control occurs.
PASSIVE SAFETY HOLDER
Securely parked when not in use.
During training, the handle slides freely along the shaft. When it is not in use, it can be moved into the Passive Safety Holder.
The holder keeps the handle securely in its parked position and helps prevent it from sliding down the shaft unintentionally.
To resume training, lift the handle out of the holder and confirm that it can travel freely along the shaft.
Before exercise, check that the handle is fully released from the holder and moves freely.
Watch how the handle is moved into and released from the Passive Safety Holder.
02 — SHAFT TILT AND SUPPORT
Adjust the reference to the individual task.
RING
Height-adjustable tilt boundary
Move the Range Control Ring vertically to leave shaft tilt free, define its maximum range or support the shaft.
HANDLES
Height-adjustable support
Move the support handles up or down to suit the user’s body dimensions, starting position and intended exercise.
LOCK
Defined positions
Lock the ring and support handles securely after selecting their vertical positions.
The ring controls shaft tilt and support; it does not limit the handle’s travel along the shaft. The support handles provide a separate physical reference for the user.
03 — PRACTICAL ADJUSTMENTS
Set the height. Set the training weight.
The video demonstrates how to reposition the Range Control Ring and support handles. The accompanying instructions explain how to add or remove weights from the weighted handle.
VIDEO
Adjust the ring and support handles
Support the component, open its height-adjustment clamp and move the Range Control Ring or support-handle assembly vertically to the required position. Close the clamp fully and confirm that the component is firmly secured before use.
STEP-BY-STEP INSTRUCTIONS
Add or remove training weights
1Retaining clamp secured in the upper position2Retaining clamp lowered onto the installed weight stack
The retaining clamp secures the selected weights on the weighted handle.
To add weights
Open the retaining clamp and slide it all the way up.
Close the clamp in this upper position.
Insert a weight through the loading slot in the weighted handle.
Allow the weight to slide all the way down.
Open the retaining clamp again.
Lower the clamp directly onto the installed weight or weight stack.
Close the clamp firmly.
To remove weights
Open the retaining clamp, slide it all the way up and close it in the upper position.
Remove the required weight or weights through the loading slot.
Lower the clamp directly onto the remaining weights and close it firmly.
Always check that the clamp is fully closed and that all weights are securely retained before training.
04 — INERTIAL RESISTANCE
Three contributions. One movement task.
01
Inherent inertia
The mass of the shaft and selected handle resists changes in their motion.
02
Added-mass inertia
Weights fitted to the S handle increase mass in combinations beginning at 25 g.
03
Rotational inertia
Mass and its distribution affect the resistance as the keyed shaft-and-handle assembly rotates around its axis.
These contributions are not three interchangeable “weights”. The mechanical demand also depends on configuration, handle position, direction, speed and acceleration.
