HERE’S WHY THOUSANDS LOVE TIDAL TANK:

Excellent Core and Balance Assistance

Recommended by my Doctor of Physical Therapy, I added the Slim Tank to my in-home workout routine to strengthen my core and improve my balance. It’s easy to use daily, and I’ve quickly noticed the benefits building with each session. The results have been so positive that the Slim Tank has become my favorite exercise tool.

Great Baseball Training Product

I recently purchased the Tidal Tank Slim to enhance my son’s baseball strength training routines. This product is a unique capability that reinforces baseball specific movements, while also leveraging the unique strength training that the free form water weight offers. The exercise content included with the tidal tank product is excellent. Must have for any baseball player as it supports all hitting and throwing movements!

Dynamic Workout for Pitchers

It really helps pitchers feel trunk rotation. Unlike a sandbag, it feels a little different each time and also teaches them to control the turn. The build quality seems great after a week. The valve system is simple and works way better than I'd hoped. It's a good product; I may get a few more.

Chris L. - Verified Buyer

Why Choose the Tidal Tank?

If you’re looking for a lighter, easier-to-handle option, the Tidal Tank Slim is the perfect fit, especially for younger athletes or anyone who are just starting to train.

SCALED-DOWN SIZE, SAME STABILITY

The Slim delivers the same left-to-right water displacement as the Classic, but with less volume. It’s easier to handle, making it perfect for younger athletes and anyone building coordination before progressing to heavier instability.

Sport-Specific Instability

The Slim is ideal for coordination-heavy, skill-based exercises. Whether you’re swinging a bat, racquet, or club, the shifting water adds resistance to real sport actions, teaching your body to move with stability and precision under pressure.

Improve Coordination in Every Rep

With less water to fight against, the Slim gives you just enough instability to challenge balance and body control without overwhelming you. Every shift of water forces stabiliser muscles to react, building controlled movement patterns that transfer into sport and daily life.

Lightweight, Portable Instability

Smaller and lighter than the Classic, the Slim is easy to inflate, carry, and use in tight spaces. It adds instability to lifts, swings, and throws anywhere you train — at home, outdoors, or on the field.

Sphere

The straps are too big and are not adjustable, would make alot more sense and would be better with adjustable straps 100%

I am a ...: Sports/performance performance coach

Very Useful

Regardless of their baseball application or any sports specific application, they are very useful implements. The construction seems rather durable, but I've only had them for a couple weeks. Regardless, I'm a big fan of their uses. I already ordered a second set.

I'll be using them for training athletes and general adult fitness as well. Good feedback for rotation with athletes, and great balance challenge for general fitness.

Tidal tank

Ordered the title tank bundle for my grandson . Great quality easy to use.

This is me, Lupko,
founder of Tidal Tank

For 10 years - from 2007 until 2017 - I suffered from pain and lack of mobility due to shoulder impingement.

Or so I was told by the many physical therapists I spoke to during that time.

What they couldn't fix in 10 years, my newest physical therapist could fix in 6 months, by making me do all these challenging exercises to keep my shoulder from locking in creating its own impingement.
