Gym Work For Johnny

February-June, 1990.
Even after beating Carl Drefus, it was clear that JJ had to improve his stamina if he was to be able to go the distance and win. His stamina was always less than average, in part because he'd won all his early fights in the first round. However, if he wanted to progress he'd need to be able to last in the close bouts.

Footnote: in fact Johnny failed to increase his stamina but raised his strength and ability to beat the count instead. Strange that he opted for gym work rather than get out on the road!
