I'm kind of torn - a part of me wants to downsize to a more acceptable walking weight and maybe try and enter a physique show. A good friend of mine just got his IFBB pro card in the physique division, so it kind of piqued my interest.
Another part of me wants to say fuck it and see if I can bulk to 300lbs and make a serious run in bodybuilding. I weighed as much as 293 in August, but I felt awful. I am about 281 right now and have managed to stay fairly lean (enough to see my abdominal wall and serratus outline at least), so I think 300lbs is doable if I clean bulk.
Then there is the pragmatic/practical side of me who says "Your 30 and will never a pro bodybuilder, why don't you focus on your health and stop being so stupid".
I switch back and forth between the three multiple times per day.
