Try tying a rope to a dumbell and make sure it won't slide around (a hockeystick piece with a hole is perfect) then tie a weight to the end of the rope and roll it up slowly and then down slowly, you'll feel it right away, by the end I can't even close my hand

Why push to failure, when you could press to success
