Leverage.

I like ropes because they give that extra extension at the end. Definitely harder though.

THe easiest would probably be the V bar. Like ass said we use the ropes alomst exclusivly. They add in more muscles and exertion. A stright bar isn't bad if your wrists can handle it. I use them sometimes too.

AN interesting though. If a tricep excersize feels the same orharder with lighter wieght. Are ytou still getting the same or more benifit?

i guess it might make sense if you compare kickbacks and CGBP and then ask which will be lighter and which will give better results?

YOu need to compare apples with apples though. tHis is apples and oranges.
