The AquaBLAST® Story

AquaBLAST started as a plastic milk jug...

My aquatic journey began on a softball field in Ohio. It was the sixth inning, a tie game, and a man on first base. The batter hit a screaming line drive into right field. The runner took off. I fielded the ball, reared back, and threw an incredible game-saving throw to home plate – I WISH! 

In fact, the ball barely travelled 50 feet as searing shoulder pain "threw me out" with a season-ending rotator cuff injury.

My doctor advised aquatic therapy for recovery, and I began a daily workout in my backyard pool using pool noodles and foam dumbbells. My recovery was coming along, but the foam accessories lacked physical weight — I wanted to build strength using actual weights in the swimming pool.

 AquaBLAST started as a water-filled milk jug and evolved into a punching bag and multipurpose aquatic exercise device for swimming pools

I tried different types of homemade weights in the pool, until I discovered that water-filled milk jugs made great 8-pound kettle bells and resistance weights. I used the jugs below water for drag and resistance drills, and above-water for weight training; they were cheap and very effective.

My lightbulb moment...

To make the weights lighter, I removed some water and added air. This caused the jugs to "float" near the surface, but mostly underwater. As a jug floated by one day, I punched it and discovered that the water-filled jug was flexible, and I could punch and kick it without injury.

Then by adding a small counterweight, I stabilized the jug so it “floated” underwater in a neutrally buoyant position.

Aqua BLAST underwater punching bag for swimming pools. The "Big Red Tomato"

I continued tinkering and eventually designed a working prototype made from stuff at the hardware store. I filed for a utility patent and now have been issued three patents on the device.

In 2019, I met a talented product designer from Portland who helped me to redesign the bag and to located manufacturers. His design insight helped transform the device into the commercial product it is today, and he continues to advise and assist with new designs. 
Aqua BLAST is compact and fits in a convenient carry case, so you can take it with you

AquaBLAST officially launched in July 2020 and we launched on Amazon in August 2020. AquaBLAST has been recognized by the Aquatic Exercise Association, Aquatic Therapy and Rehab Institute as well as numerous experts in the field of aquatic fitness and therapy as an innovative product.

We have two exciting new products planned for 2022:

AquaBLAST 20L (Mini).

The 20-liter version is smaller than the original AquaBLAST bag, and redesigned inside and out – literally! The AquaBLAST 20L is lighter and easier to handle and sets up in only 30 seconds, plus I have made several design changes. The 20L allows weight adjustments from 5-40 pounds in seconds, making the bag suitable for weaker clients. The 20L needs a few final touches before it is scheduled for production with the factory. Look for the 20L release in 2022.

AquaBLAST Suction Tether

We have partnered with, a German company that invented a high-tech suction cup that sticks to most pool floors underwater using the Clingfish Effect.

Modelled after the Northern Clingfish, a tiny fish with a powerful grip, the powerful bio-inspired suction cup, when combined with an adjustable tether cord, creates a portable platform for AquaBLAST in 3-5 feet of water.

The suction tether allows independent movement around AquaBLAST for non-stop kickboxing action. The tethering system will make group aqua kickboxing classes a reality and provide new ways to work out and have fun in the water (projected release – 2022).

Strength in Water®

RomaQuatics, our parent company, literally means Strength in Water®. The name is derived from: Roma, which is Greek for strength (ῥώμη), and Aquatics for water. 

Our mission is to create portable aquatic fitness gear that promotes strength, fitness, and conditioning in water regardless of age or physical limitations.

As a US Army Veteran, my vision is to donate a portion of profits to wounded veteran and first responder programs. This charitable component is still in early planning, but my heart is set on it. I believe AquaBLAST will increase the quality of life for our hero veterans and first responders that have been injured in the line of duty.

Dive in and Start Working Out in Water

Whether you are training for competition, recovering from injury, participating in group exercise or want to burn off steam, our low-impact aquatic fitness bags and accessories provide upper body, lower body, and core conditioning using the therapeutic benefits of water resistance. 

AquaBLAST is a single piece of portable equipment suitable for functional strength training, allowing you to incorporate everyday movements, such as lifting, gripping, stepping, and moving in the weightless environment of a swimming pool.  

Aquatic exercise is well known for reducing muscle and joint stress and eases the pounding your body absorbs from land-based activities like tennis, running, boxing, and treadmills. Water provides a near weightless environment to perform a wide range of movements without the stress on muscles, joints, and ligaments. Water also cools your body so you can work out longer and recover faster, plus water submersion actually lowers your heart rate. 

AquaBlastFit is rethinking water aerobics -- stop dancing and start BLASTING!
