Workout quesition

[WeezyBengal]

Went to the gym last night and worked out back and biceps for the first time since before Christmas (took some time off but am getting back into it this week).

I did:

3x6 wide grip pull ups
3x6 one are dumbbell rows
3x6 lat pulldowns
3x6 cable rows

3x6 dumbbell curls
3x6 hammer curls
Burnout on barbell curl, light weight.

My question is, today my biceps are sore, not really sore, but sore. My lats and back feel normal. Not sore at all. Does this mean im not hitting them hard enough? I feel like I completely wasted a workout....
