Evolution of the Dumbbell
The polarized weight distribution of traditional dumbbells creates erratic and unpredictable shifts in the center of gravity. By reducing the moment of inertia to near zero, jBells are an elegant solution that evolves handheld resistance training.
The Weak Links
The weak links of the human body - grip strength and wrist stability - are the limiting factors to efficiently recruiting larger muscle groups. The fulcrum point creates a leverage axis to maximize range of motion, planar movement, and contraction potential.
The design unlocks the most important aspect of athletic training - creating resistance across infinite planes.
Form Follows Function
The brutalist aesthetic is a result of better physics.
