Synopsis:
Clark Kent joins a gym that claims to make strong men out of boys in only six weeks. Clark suspects the gym is run by racketeers and is proved correct when he discovers phony gym equipment. When he attempts to expose them as Superboy, one of the boys proves that the training really works. Superboy is humiliated, but visits the gym again as Clark. He then drinks several bottles of the racketeers' strength tonic and pretends to become powerful, then sick. The crooks make a run for it, but Superboy captures them. He exposes their hoax and clears his own name for failing to prove their guilt the first time.
