LET'S GET PHYSICAL centers on a slacker named Joe who, with every breath he takes, makes a reluctant comeback in the fitness industry after his dad, Colonel Tom Force, a.k.a. "The Godfather of Aerobics," unexpectedly passes away and wills his son the broken-down family gym. In a "Brewster's Millions"-type switch to receive the family fortune and estate, Joe must take on his arch-nemesis, who has become a highly successful fitness entrepreneur. Against all odds, they face off in the ultimate battle of masculinity…The National Aerobics Championships.
