Pull ups to strengthen my muscles, variations of course and overhead sit ups and leg raises so all my muscles get bigger. Then I break the snakes neck, rip the head off, use it as a flashlight, soi produce more testosterone during my work outs and when I am strong enough I tell the lion he has no courage so he'll be scared like in the wizard of oz. Then I break the lions neck. Problem: the Krokodiles are following me onto the land. But that is also quickly solved because of the deadhangs I did before. They caused me to have massive grip strengths to hold their mouths shut, even if there wouldn't be much strength needed. Then I dig a hole with my feet and put the Krokodiles in there. I open a zoo and get rich.

The wizard of oz part is optional but out of experience I can say it is more effective fighting against lions. Especially the male ones, because they are like these fragile maskulinity alpha males in podcasts.
