LA Fitness kicks mother, son out of gym Published: May 1, 2014

PALM HARBOR - Pumping iron builds a lot more than just muscle for Krista Grubb, reports Fox13.

So naturally she was thrilled when her 13-year-old son Mason also began to take an interest.

They started working out together at the LA Fitness on U.S. 19 in Palm Harbor, where she's a member. She said everything was fine until last week.
