The first portable kettlebell using water for dynamic resistance—perfect for functional workouts at home or on the go.
Gumball – the ultimate kettlebell for fitness on the go. Experience the power of dynamic water resistance packed into compact, travel – ready design.
Whether you’re traveling or love workout and functional training, Gumball is made to fit seamlessly into your lifestyle.
With its adjustable weight system 0 – 35 lbs (16kg) and sturdy handle, Gumball provides a workout as effective as traditional kettlebells, but with the added challenge of shifting water weight to engage your core like never before.
Instability training
Instability training forces your muscles to work harder by challenging your balance with shifting water. It helps improve core strength and balance, essential for both athletic performance and everyday movement.
This type of training also enhances joint stability and can reduce the risk of injuries by improving muscle control and coordination.
Instability exercises promote functional strength, making your workouts more applicable to real-life activities and improving overall body awareness.
