LOMPOC, CAThe Bally Total Fitness membership purchased Monday by Alex Scarbe already appears destined for failure. "I really should go buy some new shoes, so I can come back tomorrow and work out," Scarbe said, moments after completing the membership paperwork. "Just getting in here and signing up is enough for today. I think I'll reward myself with a smoothie." Scarbe will return to Bally's twice in April, then once in May to use the whirlpool, and ultimately cancel his membership in 2007, when he notices Bally listed on his credit-card statement.
