This construction achieves such functions as to train arm muscles, to enable simplified configuration, easy assembling process, lower production costs, convenient operational procedures, adjustable weights, and better training efficiency, etc.Field of SearchUtilizing weight resistanceIncluding stationary support for weight Having guide around or through weight Having lever carrying the weight Handheld bar with weight at each end (e.g., barbell, dumbbell, etc.) or component thereof Having securing member (e.g., locking collar, etc.) for retaining weight on bar Bar held by single hand of user (e.g., dumbbell, etc.) Club Stripping layer having radiation polymerizable or cross-linkable composition From ethylenically unsaturated monomer | |
