Tidal Tank x Ultimateinstability
Ultimate Instability is a staple in elite sports teams’ training, used by the likes of FC Barcelona and San Antonio Spurs.
Ultimate Instability pioneered the water weight training movement and revolutionised what it means to train “functionally”.

Why Tidal Tank?

Reset and improve movement patterns
The power of a 'live' weight
Tank is constantly in motion, reacting to your every move. This turns any one-dimensional exercise - of your brain telling a muscle what to do - into one of many dimensions, as your proprioceptors, motor control, core, larger and smaller stabilizing muscles all have to work together.

Maximize joint stability

The power of co-contraction
Tidal Tank training improves power output and injury resilience by enhancing co-contraction, which involves the simultaneous contraction of smaller muscles around a joint to stabilize it during athletic movements. The Tidal Tanks' unique feature of erratic displacement of water makes it an effective tool to train these muscles, thereby building overall power and injury resilience.
