The TRNR HydroBag is designed for ultimate instability training.

It will challenge both your trunk muscles and postural control for improved core strength, spinal mobility, joint stability, coordination, balance, and proprioception.

As the water constantly shifts inside the bag, it creates the ultimate instability, requiring greater activation of the stabilising muscles in your core and limbs to maintain your balance.

The horizontal and vertical handles let you perform a variety of exercises that mimic multi-planar functional movements and can help you prevent injuries.

When empty, the Hydro Bag becomes lightweight, making it perfect for both travel and storage.


Up to 15  or 25 kg of water capacity.
Double handle position - vertical and horizontal grip.
Convenient load change - all you need is water.
Leak-proof, heavy-duty construction.
Convenient step pump and special adaptor included to fill up any void with air.
Hybrid valve specially engineered to prevent both water and air from escaping.
