## Description

desertcart.com: Sandbag Filler Bags - Universal 25lb Fillers, 19" X 3" - Sand or Water : Sports & Outdoors

Review: Great for PT exercises at home - I needed weights at home for PT and these are perfect because I can adjust the weight as needed. I'm recovering from back surgery and particularly use these for bridges to build strength. Right now I'm using the small and medium ones. The medium and large are a bit wobbly and unruly since they're so big. I am going to follow advice from other reviews and get a weight bag to put them in. That will make them easier to manage and I really like the idea of being able to combine the different sizes to increase weight as necessary. I think putting them in a weight bag will also encourage me to use them for other exercises as I build strength. These are awesome! I told my PT he should recommend them to patients who need something similar.
Review: Good Workout - Have only used them a couple of times because I just purchased them. I am using them for a workout challenge. Work great with water. I found them easy to fill using the faucet in the laundry sink. I didn't fill completely full because I wanted the water to move around so I would have to engage my core to stabilize the load. They seem to be durable, and no leaking.

### ⭐⭐⭐⭐⭐ Great for PT exercises at home
*by K***K on March 8, 2023*

I needed weights at home for PT and these are perfect because I can adjust the weight as needed. I'm recovering from back surgery and particularly use these for bridges to build strength. Right now I'm using the small and medium ones. The medium and large are a bit wobbly and unruly since they're so big.

### ⭐⭐⭐⭐⭐ Good Workout
*by D***S on February 28, 2020*

Have only used them a couple of times because I just purchased them. I am using them for a workout challenge. Work great with water. I found them easy to fill using the faucet in the laundry sink.

### ⭐⭐⭐⭐ Almost Perfect
*by M***E on October 19, 2022*

I have purchased multiple of these bags in various sizes, and they have all held up far longer than the "high end" filler bags put out by the best bag makers. I couldn't be happier with them, except in the larger sized 120# bag. Why is the fill port on the side? It makes it an absolute nightmare to fill up by yourself. In the pictures, they are all on the end (which is perfect). So, why the change on the bigger ones?
