How Hydro Training Really Works

How Hydro Training Really Works

Hydro Training is emerging as a hot topic of conversation in the fitness and conditioning worlds, and represents a new training frontier. The discussion is being driven by water-filled products such as the SURGE® Storm 40 and 60, and the SURGE® Hydro Ball.  

What is Hydro Training?

Hydro Training uses the reactive properties of water, in water-filled fitness equipment, as unstable resistance-training tools. The inherent properties of water offer reactivity, volatility and unpredictability, which result in positive training outcomes. The concept behind Hydro Training is based on using the dynamic resistance of water to enhance performance and overall conditioning because of the constant, variable challenge presented while using water-filled equipment. 

Why Use the BOSU Surge For Hydro Training?

Hydro Training, utilizing the SURGE® Storm or SURGE® Hydro Ball, checks a lot of boxes when it comes to matching with a number of 2020 fitness trends. While the Storm and Hydro Ball are favorite pieces of equipment in the emerging hydro training category, they also fit right in with this year’s trends that include high-intensity interval training (HIIT), small group training, stability and balance training, loaded movement training, personal training, functional fitness training, circuit training, and outdoor training. 


Everyone, trainers and consumers alike, are constantly looking for new and legit ways to make their workouts more fun, varied, engaging and effective. And Hydro Training helps shore up weaknesses in conditioning programs related to having a comprehensive and complete approach to training in place. 


Hydro Training with the SURGE® Storm and Hydro Ball keeps workouts fresh and progressing, and can have a big effect on total calorie burn, improved fitness levels, reactivity, strength, stability, balance and body control. 


How Does Hydro Training Work? 


To understand how to use this approach in your training, you have to dial down on what makes Hydro Training effective. The big difference between static load (e.g., dumbbells, kettle bells and barbells) and dynamic load (e.g., SURGE® Storm and Hydro Ball) is the reactive stabilization requirements that occur with the volatile and unpredictable nature of water.  


Hydro Training products like the SURGE® Storm and Hydro Ball provide an unstable training load -- water that is constantly shifting and moving -- in reaction to your movements.  Water action inside the Hydro Training products allows for unlimited movement and stabilization challenges, along with product designs that offer the freedom to create integrated, functional, total body exercise options. 


Hydro Training requires whole body, integrated training as you adjust to and control the unpredictable movement of water. Bottom line, better “body control” is developed. And your ability to optimize technique, avoid injury, improve performance and lift heavier loads can all increase. Of course, muscle strength, endurance, power, mobility and improved metabolic capability are all possible outcomes depending on how you program the training loads and movement complexes, as well as utilizing varied water actions that can be created while using the SURGE® Storm or Hydro Ball.
