I was trying to be inovative with the equipment i have at home and came up with this noval idea for a lift.
Basicly you get an declined bench and lay back in it with your legs locked at the top as though you were going to do a sit up. Then you hold a dumbell in each hand out streched so that your arms are parallel to the floor (this should put your bicep in a streched position). Then you do a conventional sit up but as you go up you bend your arm at the elbo and keep your forearm parallel to the floor.
The benifit is that not only does this make the bicep curl start from a strech position but it allows the whole range of motion to be under tension i.e. because the torso moves gravity is always against the direction in which the dumbell is moving.
as opposed to a convetional curl where the top of the motion is pointless cos gravity stops acting againts it.
I've only tried this a couple of times and because i'm a beginer i don't know if what i'm doing is stupid or genius.
