Hell no, I sit here at work counting down the minutes until i can get over to the gym. My wife says i'm obsessed, because in another thread someone told me to take some time off from the gym and she said i was in the worst mood.
But i think i figured out part of the not feeling it thing. I think maybe my form was wrong especially on the abs, someone said don't just do the motion contract the muscle you're working to get that motion. That advice seemed to work more now instead of focusing on doing the crunch or curl i focus on just contracting my bicep and letting it move the bar. I guess movements involve a lot of other body parts than just the one you think you're working.
You are exactly right on the contractions. Learn how to do that for everything you do. Then start to add weights as u progress. if it gets too heavy were you don't feel that contraction, drop some weight back. Unless you are a competitive powerlifter, squeezing muscles are what you want. You will become more efficient in training and will develop better with lower weight than someone that just slings it around.
