Well... DID you do squats??
Seriously, feeling beat or sore the next day is not a good indicator of workout effectiveness. Sure, sometimes when you really push it you get sore. Especially in the first years of training. But trust the tape measure, mirror, PR's, and admiring looks from the ladies over how much pain your muscles are in.
I like to stick with the big compound lifts but sometimes I do a day or two of dumbell work. I'm lifting less weight overall but the change in routine usually has me feeling it the next morning. Some variety also keeps thing interesting and helps keep your body balanced and injury free. Just keep at it, you'll be sore again soon. Bet on it.
Again Seriously... You DID do squats, right??
