Through this Onnit HydroCore Bag review, you will learn how this bag is unique from traditional gym equipment. Also, the uses and benefits of this bag to get the best out of your cardio training.

What is Onnit HydroCore Bag?

The HydroCore bag is a piece of training equipment invented for MM Fighters, celebrities, and military personnel trainers by Maurizio Tangari. The concept of this device is quite similar to other traditional training gear “Bulgarian Bag.”

Ancient Eastern European wrestlers followed different methods to develop functional endurance, stability, and strength. For this, carrying small firm animals on their shoulder and back was one of those methods.

Thanks to the animal cruelty laws and technological advancements – HydroCore bag replaces livestock, and wrestlers don’t have to tote livestock anymore. It is a yoke-shaped plastic bladder and consists of a harness that is attached to oxen.

The difference between the Onnit Hydrocroe bag and the Bulgarian bag is that Onnit uses water while the Bulgarian bag uses sand for loading.

When this bag is lifted to perform different exercises, the water sloshes around in the bag, creating a motion called water dynamics. To train different athletic qualities, here, the bag controls your movement.

  • Rock-solid stability
  • Strength and explosiveness
  • Better results with less weight
  • Easily transportable training
  • Instant feedback

What Benefits does Onnit HydroCore Bag Offer?

Are you a martial artist or an athlete? A HydroCore bag is a must-have training gear that offers the below benefits to a bodybuilder.

Develops Rock-Solid Stability

With the water circulating inside the bag, you can move your body to any position. Your body alignment, the exercise form, and the control of the bag – you need to be extremely aware of all 3 and stop another unnecessary movement. This way, you can gain impressive balance and incredible stability.

When training with this bag, you have no other choice except maintaining balance and stability. You will lose control of yourself if you can’t.

Improves the Technique of Exercises

The wrong exercise technique may lead you to injury. So, performing the exercise properly is of utmost importance.

The purpose of the HydroCore bag is to let you familiarize yourself with proper exercise techniques. If you can exercise adequately, be sure that you will start feeling pain in different body parts.

You can’t perform dynamic moves such as the pendulum if you follow the wrong technique. So, mistakes can be identified immediately, and a prompt correction will happen. In the pendulum exercise technique, you can learn to move with the water momentum. Controlling the bag will be harder if the timing is not correct.

A good technique on bag exercise will translate into a better technique in your other lifts, as your body stability and awareness will improve.

Boosts Up Explosiveness and Awareness

As a result, your training becomes practical and suitable for multiple sports such as wrestling, MMA, and football, where defeating a living and forcing life is mandatory.
