Cable belt folds into a bag easily. I wore mine for most of the past year, with breaks for work each day. Other than that belted most of the time.
Depending on the season I use either latex oil on the cable, or I use a singlet / corset / body shaper underneath it for a little more comfort.
I know you are aiming for big things, but seriously... just get a cheap cable belt to play with, aim for hours (not days) and have some fun to begin with. 24/7 is years away.
