Our Story

Tidal Tank was created after our founder discovered the benefits of water-based training while recovering from shoulder impingement.

By combining implicit training with the natural, shifting resistance of water, they found a faster, more effective way to heal and build functional strength.

This breakthrough inspired the creation of Tidal Tank – a tool designed to harness the power of water for dynamic, adaptive training.

Our Mission

Our mission is to revolutionize fitness and recovery through water-based training.

Tidal Tank offers a unique way to build strength, stability, and resilience by tapping into the fluid, dynamic resistance of water.

We’re here to help you move better, recover faster, and train smarter.

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 using Water Dynamic Weight.

OUR FULL STORY
How water weights helped me finally recover from shoulder impingement
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 using Water Dynamic Weight.

A little background: let there be pain! 😫

It started when I was 16 years old.A little shoulder pain turned into a lot, and before I knew it, I could no longer do any of the activities I so adored. No swimming, no martial arts, not even a single push up.

The verdict Shoulder: impingement, caused by too little room in my shoulders.

I had the label. But after 10 years of seeing many physical therapists, the pain and lack of mobility were still there. 😫

All the therapists had me doing the same repetitive elastic band shoulder exercises and they all gave me very detailed instructions on how to position and move my back, shoulders, and arms

The turning point: meeting the Dutch shoulder magician 🧙

Through a stroke of luck, I heard about a mysterious shoulder specialist, who had a practice in a small rural town in the Netherlands.

Apparently, he didn't do things 'by the books', and had created a unique treatment method, that was wildly successful.

After years of failing shoulder therapy I decided to give it another go before heading to surgery.

So off I went, to see Wieger Heijenk at the Luxor Physical Therapy center in Zeewolde.

First session - lack of mobility (and off-camera pain)

He first had me do a simple test: raising my arms fully upward.

As you can see, the mobility of my right shoulder was clearly limited.

My left shoulder was limited as well, but it's harder to see on the video.

What the camera doesn't capture, was that this movement was rather painful, so I preferred to avoid it.

The Method
Let the body fix itself using dynamic water weights 🌊

Wieger told me there are two types of learning.

 Most therapists, all of mine included, only focus on the first:

1. Explicit Learning

The Traditional and Coach focused approach.
The coach (or physical therapist) tells the athlete (or client) exactly how to perform a task.

2. Implicit Learning

The New and Athlete Focused approach.
The coach (or physical therapist) gives only minimal instructions on what to do, never saying how to do it. Rather, he/she gives constraints allowing the client to learn the best way to do the task implicitly (subconsciously by him/herself).

Water weights give the direct feedback needed for implicit learning

Static weight

  • ➡️  Client deviates to the left
  • ➡️  shoulder locks itself in
  • ❌ shoulder impinged 
  • ❌ limited range of motion

🌊 Water weight 
(while standing on a BOSU)

  • ➡️ Client deviates to the left 
  • ➡️ water reacts directly, sloshing to the left 

  • ➡️ client subconsciously unlocks the shoulder 
  • ➡️ achieves full extension of the arms
  • ✅ shoulder moves freely 
  • ✅ full range of motion

So, I embarked on my water training journey. Starting of with exercises such as the ones below.

Soon, I was able to do moves
I deemed impossible before 👇

After just 2 months, the shoulder issues I carried with me for 10 years had disappeared & I had full mobility

Under his guidance, the pain and lack of mobility almost completely disappeared after just 2 months! For me, this was absolute magic. I could not believe how much improved in such a short time.

I never imagined I would come this far. I want to sincerely thank Wieger for fixing
my shoulder, and inspiring and helping me to start Tidal Tank.

Before

After

The birth of Tidal Tank

I fell in love with the water weights I used in physical therapy. They were really fun to workout with, there are endless of exercises to do with them, and it was easy to increase the weight.

Moreover, most important for me was exactly was that auto-corrective element.

I knew that the direct feedback I got from the water would keep me from developing hurtful movement
patterns and keep my shoulder free from injury.

I wanted one for myself, and for the entire world for that matter.

There was one problem though: they were all either bad quality, or overly expensive.

So I decided to manufacture and market my own.

After spending a year looking for the highest quality materials and crafting my brand, Tidal Tank was born.

My mission: share the benefits of the Tidal Tank and its unique implicit learning qualities with the world.
