Pro Series Expandable Weights

The system includes integrated micro-weights that allow you to fine-tune your resistance by 2.5 or 5-pound increments. You simply add or remove these smaller weights within the handle assembly to bridge the gap between larger weight jumps.

While the shape is different from traditional round dumbbells, the open-handle architecture is specifically designed to maximize your range of motion. It prevents the weight stack from interfering with your wrists or forearms during movements like bicep curls or overhead presses.

The magnetic selector pin is designed to lock firmly into the weight rails, ensuring the plates remain secure throughout your set. As long as the pin is fully inserted into the correct slot, the system remains stable and safe for standard strength training exercises.

The grip diameter is 1.5 inches, which is a standard size for most strength training equipment. While the open handle design offers more clearance, those with very small hands may find the grip slightly thicker than a standard fixed dumbbell.

The urethane coating serves two main purposes: it protects the steel plates from chipping or rusting over time, and it helps dampen noise when you set the weights down. It also provides a smoother, more balanced feel compared to raw cast iron.

Yes, the open-handle design is particularly advantageous for chest presses and pullovers, as it allows for a more natural wrist position. However, because the weight stack is rectangular, you may need to adjust your form slightly compared to using round dumbbells.
