Hey bro, dun give up. I read that ur targets are

-Eliminate my man boobs!
-Gain more muscle
-Flush that flabby tummy!
-Able to lift heavier
-Reduce more body fat

If there is some progress in any of the above then its working. Maybe some objective measurements will help.

Your last few exercises has been going down in weightage. Rippetoe's program lasts frm 3-6 mths, so yours started in sept, mayb its time for a rest as you mentioned. Or a change of exercises or some sort of change. I'm not well-versed in this, maybe other bros here can enlighten.
