What are the unique features of the HydroWorx EVO?

Fits in Just 30 Square Feet

The unique foyer design of EVO means that there is no need for an extra water storage tank, the water is maintained within the unit chamber, dramatically reducing the amount of space needed.

Adjustable Water Depth From 1″-50″

Quickly add, remove or adjust water levels to attain the optimal water depth for patients. Depths range from 0″ to 50” with the touch of a button

Variable Speed Underwater Treadmill

The variable speed treadmill, which smoothly increases from 0 to 6 mph in safe .2 mph increments, has a cushioned low-impact design with excellent traction.

Resistance Jets with Massage Hose

A resistance jet is essential for sports performance training, therapy protocols or deep tissue massage. The jet has nearly 200 different water speeds to choose from.


Easily fitting through a standard 36” doorway, the HydroWorx EVO requires just 30 square feet of floor space, less than any other freestanding aquatic treadmill system world-wide.

What are a few advantages the HydroWorx EVO technology provides?

Compared to land-based unweighting treadmills, the HydroWorx EVO offers the same functionality but with the additional benefits of warm water therapy such as buoyancy, the relaxing effect of warm water on muscles and joints, the strengthening benefits of additional resistance and hydrostatic pressure to reduce swelling and promote healing. In addition, the EVO allows you to move and rotate freely with plenty of space to execute multi-planar activities such as forward and backwards walking or running, side shuffle and carioca.

The completely integrated underwater treadmill (speeds from 0 to 6 mph) allows for correct simulation of land-based biomechanics. Sports specific exercises such as sprinting, marching, back-pedaling, shuffling, lateral braiding steps and plyometric activities are especially effective when performed on an underwater treadmill.

The adjustable 7” touch screen panel controls all functions of the EVO. This gives the athletic trainer, physical therapist, athlete or patient complete control from inside or outside the tank during treatment or conditioning sessions.

How long does it take to fill and empty the trainer tank?

Three minutes (1.5 minutes for the treatment chamber and 1.5 minutes for the foyer).
