Dumbbell back and leg routine

[BetaDude]

Can anyone recommend me good leg and back exercises with just DBs, I'm currently unable to go back to the gym for a couple of months but I do have have a pair of adjustable DBs at home and am having trouble coming up with a good routine for this 2 specific body parts, so far i have one arm db rows and db deadlifts for back and stiff legged DL for legs. I know gains will be slower compare to going to a normal gym but I have to do with what I have. I would love to buy a pull up bar but I dont know where to put it in my house. Thanks in advance.

Db lunges were mentioned above but in particular walking db lunges have worked very well for me

Anyone here had any experience on how to do db squat? Where should I put the DBs on my side or on my shoulders? Also what should I do for quads?
