Hi there Jane Anne~ I'm no expert, and have yet to complete Lyle's book, but I do have a thought or two about your plight.

Regarding the inches gained...
First of all, it is possible that maybe you mis-measured on the first one? Just a thought.
Could it have to with water retention?
You could be building an upperbody faster than the rest, too. Muscle weights the same as fat, just takes up less space, but if you are building muscle, then that 'could' be it.

IMHO, if you are working all these muscles 3X a week with only 1 day rest in between, you may be doing yourself a dis-service. The muscles need to rest a lot longer to recover.


Good luck to you, and I can't wait to see what others have to say on the subject.

Peace,
Brenda

P.S.~ Just on the side to anyone answering...how long exactly does it take to start "gaining" muscle from your first work out?
