why over/under grip for deadlifts?/Form

[protienpowder]

I don't get why the over/under grip is used in deadlifts.

Also, I'm not sure if I'm doing the deadlift form right. Im doing everything on http://www.topendsports.com/fitness/tech-deadlift.htm but it doesn't feel as intense as everyone says it is on here.

I use a mixed grip when deadlifting. Usually the case if one side is weaker than the other (ie. your grip)

Mixed grip is for when you get to a certain weigt where your hands can't hold completely in both places and it might slip. Mixed grip is a balance thing for when yo uget to that weight.
