well, i don't know the names of the lifts, but here is what i do. My main focus is the arms, chest, and abs.
hold dumbell by my side, lift it with one arm by flexing my elbow (classic lift for bicep)
hold dumbell with two hands behind my head, lift it above my head (seems to work triceps)
hold two dumbells at my side, raise them outwards (like a T)
lift dumbell over my head, starting at shoulder position
two different kinds of bench press; one is where i just push the dumbells away from my body, the other is where i start with the dumbells at my side and move my arms sideways in a hugging motion bringing them together
those are the lifts that i do. I basically go by what muscles feel tired when i am done lifting, but don' t really know if it is doing any good.
