  • Patent number: 9302142
    Abstract: A weight training barbell system provides modifiable barbells that facilitate the attachment of plate weights, various elastic straps, inelastic bands, handles, grips, and connectors, in a compact space saving design. The weight training barbell system incorporates various features that allow it to perform specialized exercises that provide same or greater intensity from a workout using lower weights. The weight training barbell system accomplishes this through the use of specialized components that permit a user to redistribute weight along the length of the bar and components that add resistance, in more than one direction, while lifting the bar. The weight training barbell system can be utilized to perform compression lifting exercises, offset lifting exercises, and self spotting exercises.
