HydroCore Bag
Control water to build an unshakeable body.
The HydroCore bag uses the power of water dynamics to build stability, strength, and explosiveness like no other training tool. Fold it up and take it on the road for a workout you can do anytime, anywhere—no heavy weights necessary.
Water Dynamics
When you lift the HydroCore bag, it wants to keep going in whatever direction you were moving it. The water inside it sloshes around, and your shoulders, hands, hips, and core have to work to stop it from pulling you out of position and breaking form.
Overcoming all that inertia builds head-to-toe stability—the kind you need to hold onto a resisting opponent if you’re a fighter, lift heavier weights if you’re a gym rat, and strengthen your lower back if you sit in a chair all day.
HydroCore training also teaches you good technique just by using it. The water’s momentum will help you learn the right speed and timing with which to perform your exercises. If the water sloshes a lot, you know something’s off. If it flows with you, you’re doing it right.
Invented by Maurizio Tangari, trainer to MMA fighters, military personnel, and Hollywood celebrities, the HydroCore Bag design was inspired by Zodiac inflatable boats—the kind that Navy SEALs use on top secret missions. This bag won’t spring a leak or lose its shape, even under the heavy fire of your hardest workouts.
Ensuring a no-slip grip.

Light weightThe empty bag fits easily into luggage, and 10 pounds of water is all it needs to provide a great workout for almost anybody. Less is more.
