No he had his own gym called Baldwin's. I was also a member of Golds on Tenn St., great gym.
The Golds there was a great gym, still is, as far as I know.
Baldwins' place was good too. I got to do see him train arms in there once.
He had really huge arms for a guy that light ( around 190 I think).
Baldwin had this really pretty, sweet blonde girlfriend working in the gym with him (80's).
I last talked to him about 8 yrs ago and he had a new lady in his life.
He said the blonde was a sweetheart but it never worked out for long.
Baldwin had a classic physique and is one the smarter men ever to win a major title.
