Hi all, I currently do weights and train my legs and arms on alternate days during the week. I have gradually been able to increase my weights which shows I'm doing something right

However, I want to incorporate deadlifts into my routine. I am a bit too scared to go into the main weight training area where the men are lol, and the area I am in has a set of dumb-bells so I prefer to stay there and use those, as opposed to a bar-bell.

Can anyone tell me what the difference in technique is between squats and dead-lifts please? I have looked at videos on Youtube and they have confused me more than anything and now I am unsure
