Honesty, I agree with Goatboy. Most of the strength sports/hobbies are pretty boring. Most people aren't going to sit through the various posedowns, 3 lift attempts, or c/j and snatch attempts.
The only thing I think might have a chance now on the big networks is, maybe, Strongman comps.
Also back in the late 70's - early 80's, you had a few other things that helped it a bit.
On the Olympic Lifting side you had lots of records being broken, plus East vs. West battles.
Strongman/Powerlifting had lots of neat personalities. You might even find current NFLers or small time celebrities competing in a show.
The bodybuilding side had plenty of charismatic stars too. Now, for every cool bodybuilder, you have 10 that are about as charismatic as a cinder block.

Also, I doubt any major network would touch a known heavily drugged sport anymore without it having a already built in audience like say, Football, wrestling, etc......
