The California skullcrusher is a variation of the EZ bar skullcrusher. To perform a California skullcrusher, you do a combo movement that is one half skullcrusher and one half pullover.
The additional stretch provides a greater range of motion and longer time under tension for the triceps. The California skullcrusher is an effective tricep builder and should be included in your workout programs, at least for a mesocycle.
