at the same time don't stress yourself. no hard exercise so try not to take long walks just ot shoot a nice scenic picture . just join model shoot where you can stand still and the model poses for you .
are there any model shoots where i can don't shoot, the models carry me in sedan chair
then sit me down on a throne and feed me food nonstop?

It can be done if all you want is to be supersize into a big ball of lard with a ticking time bomb of a heart. Or you can go the other way and take up body building. Building big gun biceps like Governor Arnie
