Aquatic exercise is a low impact tool that yields high impact results with limited joint stress and muscle fatigue. Water creates a safe environment where anyone can achieve a great workout without risking injury. Water exercises also have the amazing ability to speed up recovery from an injury or maintain health. From upper body exercises, swimming, running, and conditioning, there is no limit to what can be accomplished in a pool.

This ultimate training and rehab aquatic tool is a win win all around. The answer to why it works lies in three basic principles of water: Hydrostatic Pressure, Buoyancy, Viscosity.

Here’s a simple explanation of what they are and why they are so important to aquatic exercise success.


Hydrostatic pressure is the weight of a fluid – in this case water – against an object. When an athlete gets in the water, hydrostatic pressure creates a uniform support system for all immersed body parts.

A. Water completely surrounds a submerged body part from all sides for a complete support system.
B. The deeper you go, the greater the support you get from the surrounding water. This effect creates a secure environment to prevent injury from falling, imbalances or over-stress.




Buoyancy is the ability to float in water. The deeper you go, the less weight you have to bear. Based on buoyancy principles, an athlete immersed in water up to their neck bears 10% of their body weight. If the water is at chest level, they bear 25% of their weight, and if the water is at hip level, they bear 50% of their weight.

Water’s zero-impact environment is ideal for getting in shape or recovering from an injury.  The weightlessness means you can get an intense workout with less joint stress and pressure. Stretching out tight muscles is much easier because water’s buoyancy helps improve range of motion.

In addition, it can help rehabilitate without further straining injuries. Many common injuries can be managed with aquatic exercise.  Taking weight off any injury allows for therapy protocols too begin much sooner than traditional land-based treatments. This means rehab can be accomplished sooner.



Viscosity is a fluid’s resistance against an object. In this case, water. The resistance or drag of water, combined with hydrostatic pressure and buoyancy, creates the ideal environment for training and therapy.

Exercises in water provide up to 15 times more resistance that the same exercises on land.  When a water current is added with varied speeds (available in most swim spas), this can ramp up the intensity of workouts or create treatment protocols to help athletes successfully progress different stages of recovery.

Aquatic fitness and therapy is the ultimate environment that boosts confidence to continue exercise as it supports. This means achieving aquatic exercises with proper mechanics, less pain, faster results, and better outcomes.
