I bought the Tidal Tank Sphere after seeing some baseball training videos and decided to give it a try for home workouts. Man, this thing is no joke! At first, I filled it to about 40-45 lbs of water (easy to adjust with the valve), and even though the actual weight isn't insane, the way the water sloshes around makes every movement feel 2-3x harder. It's like fighting a living, unpredictable opponent – perfect for building real-world strength, stability, and core power. I use it mostly for rotational exercises (Russian twists, woodchoppers, slams), overhead carries, and even some light throws/swing drills. My stabilizers and obliques are on fire after just 10-15 minutes – way more engagement than with a regular medicine ball or sandbag. The sphere shape is genius because the water moves in every direction, forcing you to control it from all angles. It's especially great for anyone into sports like baseball, golf, MMA, or just wanting better functional fitness. Pros: Super portable – deflates/folds small when empty, travel-friendly. Durable PVC material holds up well (no leaks so far after a couple months). Quick fill/drain with the pin valve. Forces better form and mind-muscle connection. Cons: Honestly, none major. Maybe it takes a minute to get used to the instability if you're coming from static weights, but that's the whole point – it exposes weaknesses fast. If you're on the fence, just get it. This has become one of my favorite pieces of equipment in the garage gym. Highly recommend for anyone serious about core strength, balance, or athletic performance. Tidal Tank nailed it with this one! ( – excited to try more from their line, like the KettleTank next!) Read more

As a firefighter, I was looking for ways to add free moving weight into my workouts. Love the versatility of this product with the ability to change the amount of weight by changing the amount of water. It’s great for travel as it can be emptied and deflated and refilled anywhere you have access to water. The product comes with easy setup instructions as well as the option for app workout ideas. The product appears to be built very well, item feels sturdy. My kiddo loves my large one (as you can see in the photo 🤣) and we love they offer a small version for kids. Will definitely be ordering one for her. Handles seem to be very comfortable and I don’t envision them hurting our hands at all during use. Looking forward to trying more of their items! Read more

My daughter often gets bored and is never excited about working out. Since using Tidal Tank she looks forward to her workout. She says she can feel the burn! She cranks up her music and has fun using the Tidal Tanks. Quality of the product is great! We did add vinegar as suggested and set up some reminders to change the water regularly. We feel confident she will see results and is using some sports specific exercises." Read more
