Use the dynamic movement of water to enhance your workout.
The Surge® is a unique training tool that uses dynamic resistance to enhance a user's workout. Unlike a stable tool, such as a dumbbell, the constant shift of even a small amount of water inside the The Surge™ will require additional stabilizing muscles to be engaged during different lifts or movements. This creates a more complete workout without the need for additional equipment or exercises.
Proper joint positioning and spacial awareness can also be improved through this dynamic training. Four handles can be gripped parallel or perpendicular to the tube, add to its versatility and keeping users comfortable. The Surge® is also great for twisting, horizontal, or vertical movements as well.
A built-in gauge lets you precisely adjust the weight by adding or subtracting water. No-leak, screw-on recessed cap. Its portable and lightweight design (it's only 9 lb when empty) allows it to be transported and used almost anywhere. Pound and kilogram identifiers are clearly labeled on the side.
A 42"L x 8" dia makes it much shorter while doubling the diameter when comparing it to a traditional slosh pipe, which can be up to 10 feet long and a struggle to maneuver for beginners or smaller users.
