I hear what you guys are saying and i guess i know your all right.
Your probs right, tho its kinda bothered me. I always do my main movement for say chest (Db bench) in normal Db in each hand style, but had considered my secondary isolation movement incline fly or pec dek, to be unilateral, OR 2 sets for left side whilst id do 3 sets for right (slightly smaller) side??
Its funny i tried unilateral leg pressing and my right leg (side which i think had smaller tear drop) is actually stronger than the left side which i believe is bigger,weird eh?!
