Not Sure About The Not Gaining Weight But I Increased 5 Inches In My Chest And DIdnt Gain A Single POund id say thats pretty good

Not Sure But Yeah It Is The Peck Deck Wasnt Sure What Everyone One Else Called it So I Used A Standard Name

i suck at bench though i can only do my body weight which is only 140
but i dont really care much for it.

BTW whats this butterfly machine? I hope you dont mean the pec dec.
Because if you do you better start bench pressing before i count to ten, unless you want bad shoulders when your older and a chest that cant push for crap.
why wont i be able to push worth crap and have bad shoulders i would think benching with be worse on you
