Maximize Performance & Durability with These Expert Tips
Fine-Tune the Feel with Air Adjustment
The patent-pending Swell-Air jacket is designed to enhance the water’s movement inside the bag, creating a unique resistance experience. You can adjust the internal air pressure to modify how the bag responds:
- More Air = Firmer Feel – Adds stability while still allowing dynamic movement.
- Less Air = Greater Fluidity – Increases instability for an extra challenge.
Pro Tip: With the Click Valve up, simply blow into the inner chamber to adjust the pressure.
Strong & Secure Air Valves – Built to Last
The air valves are engineered for durability and are rigorously tested to ensure long-term performance. Because of this, they may feel firm at first, but they are designed for secure sealing and longevity.
Pro Tip: If the valve feels tight, use your thumb to push it out from behind. Don’t hesitate to apply a little pressure. Swell Fitness bags are built to withstand intense use.
