Synopsis by Hal Erickson
Former serial star Charles Hutchison warmed the director's chair for The Winning Wallop. Hero Rex Burton (William Fairbanks) wants to become a professional athlete, but his wealthy father has other ideas. To prove that he's made a good career choice, Rex hires himself out as a gym instructor at a woman's training camp. For the sake of the camp's owner pretty Marion Wayne (Shirley Palmer), our hero agrees to fight the "champ" for a $100,000 purse. Offered a bribe to lose the bout, Rex turns the tables on the crooks, who retaliate by attempting to kill Marion's father and then placing the blame on Rex. A wild and perilous car chase ensues, the end result being the capture of the crooks and hugs and kisses for Rex and Marion.
