Stan Efferding, Mark Bell, Wendler, and Dave Tate, are 4 others that deserve to be up there from the strength training world too.
Stan has done extraordinarily well for himself - achieving success in a number of different ventures:
Early on, he started a telecommunications company from scratch.
He became heavily involved in real estate.
Manufactured several generations of a gimmicked shaker cup.
Does online & virtual coaching, and conducts seminars on training and nutrition nationwide.
Sells a diet plan in ebook form AND pre-packaged meals to go with it.
Is a co-owner/silent partner/investor in several businesses.
I’d imagine the man has other investments that are not public knowledge as well. The above info is derived from interviews he’s done on podcasts, as well as footage included on his DVD from several years back when he still lived in the Oregon/Washington area.
Stan was smart enough AND able to get out of earlier projects once their performances started declining in favor of new, prosperous ventures. That’s an advantage of having several irons in the fire at any given time.
