Why I Invented AquaBLAST
I didn't invent AquaBLAST to reinvent aquatic fitness. I invented it because I needed a better way to train in the water.
After building the first prototype and using it myself, I noticed something I hadn't planned for. As I added more water, the bag got heavier. Every workout became more challenging, and over time I became stronger.
Without intending to, I had created a portable aquatic training system that allows progressive weight training in the water.
That's the same principle that has guided strength training for generations: progressive overload. As your muscles adapt, you gradually increase the resistance.
In a gym, you add more weight to the bar.
With AquaBLAST, you add more water to the bag.
That simple idea changed the way I looked at aquatic exercise.
Most pool fitness equipment relies primarily on drag resistance. Drag certainly has value, but it doesn't provide a simple way to progressively increase the amount of external weight you're moving. AquaBLAST does.
Later, I found that research on aquatic exercise points to the same principle. A 2026 review of 31 studies in older adults found that aquatic training improved strength and balance, and that progressing toward higher intensities appeared to help (J Aging Phys Act, doi:10.1123/japa.2025-0083). Those studies didn't test AquaBLAST, but they support the idea it was built on: progressive challenge over time, not the water alone.
The research helped me understand why my own pool workouts kept getting harder, and why that mattered.
AquaBLAST combines adjustable water weight, drag, and buoyancy into one portable training system that can be used for lifting, pressing, rowing, squatting, rotational training, punching, and kicking. You can start with a gallon or two of water and add more as your strength improves, up to a full bag of about 40–45 lb (20L) or 50–55 lb (25L).
I invented AquaBLAST to make pool workouts more effective.
The science helped explain why the principle behind it works.
