FUNCTIONAL TRAINING

Domande frequenti - Flow bag

• How much water does the Flow Bag hold, and how much does it weigh when full?
  The amount of water depends on the filler’s capacity and the chosen fill level. Generally, partial fills (50–70% of the capacity) are used precisely to maximise the destabilising effect: the more free space there is, the more the water shifts. The total weight varies depending on the configuration — water-filled, sand-filled or a combination of both. Please refer to the product data sheets for specific values.
• Is the Flow Bag suitable for beginners to functional training?
  With a bit of caution, yes. The instability caused by the water amplifies any postural compensation, so anyone who does not yet have a solid foundation of core control should start with light loads and basic movements — carries, deep squats and hinges. Avoid explosive or overhead movements in the early sessions. A technical supervisor is recommended during the initial stages.
• Which movement patterns can be effectively trained using the Flow Bag?
  The most effective movements are those that involve load transfer between planes of movement: one-arm carries, squats with rotation, lunges with lateral movement, deadlifts and trunk rotation exercises. It is less suitable for strictly sagittal movements and maximum loads, where the variable instability becomes a risk rather than a stimulus.
• Can the Flow Bag also be used outdoors or in non-traditional settings?
  Yes. Its sturdy construction and the fact that the inner tube can be deflated make it portable and suitable for outdoor sessions, sports pitches, the beach and grassy areas. It is one of the favourite pieces of kit for summer fitness training or outdoor group training sessions. Its weight when empty is minimal, which makes it easy to transport.
• What sets the Flow Bag apart from a traditional sandbag?
  A sandbag has a relatively predictable load behaviour: the sand compacts and flows slowly. The water in the Flow Bag reacts much more quickly to changes in direction, generating reactive forces that require a faster and more continuous neuromuscular adaptation. The two tools complement each other: the sandbag develops raw strength and control under heavy loads, whilst the Flow Bag works on reactivity and dynamic stabilisation.
• How often should a hydrating filler be replaced?
  The filler is designed for long-term use, but in gym settings with a high number of users, it is advisable to inspect it periodically to check that the seal is intact. Sidea sells it as a separate spare part (SKU 8054/3) precisely to make replacement easier without having to buy the whole system again.
