Arnold Schwarzenegger may be the most expensive personal trainer in the land, because Sunday he worked out 2 crews that each plunked down $150,000 ... all for an incredible cause.
Arnold was at Gold's Gym in Venice, which he made world-famous, and made good on a charity auction at his home Saturday night.
Morris Flancbaum from Florida and his fam bid the $150k to get a good pump under Arnold's tutelage. Morris and his sons got pointers from The Terminator as a crowd formed to watch. Another $150k auction winner was there as well, getting fit with Arnold.
