it does and do not think that because you use light weight it is not effective.
See heres the thing,
I will not agree that maximum weight is the best for growth but at the same time I think you do have to provide enough stimulus to a muscle in order for it to grow. There is no way I could put on more than maybe 30-40 pounds on each side without doing the exercise properly.
So I'm thinking that the weight used will be too little to stimulate muscle growth...
Do you think any different donny? Am I wrong
