It`s just a one-arm skullcrusher.....you can also use two bells to the side of your head by your ears,or just so skullcrushers.
Started doing these & really felt it in my triceps, supposed to be a good exercise for your bench press.anyone confirm this?
do you think it helps your benches?
Not really as you can`t truly go too heavy on them.....Skull Crushers with an EZ-Bar,Weighted Dips, or Close Grip Benches I think would be better options, but who knows until you test them out?
