Simba's Fighting Skills

While reading the topic about the KM-named Nala Flip, (lmao) someone pointed out that since Simba left the Pride way early, he missed out on much of his training for fighting and normal lion lifestyle.
But when, after spending the better part of his childhood and young adulthood in the jungle with Timon and Pumbaa, Simba seems to know everything about fighting when he overthrows Scar. Do you think he learned this naturally? Did he learn it in the jungle? Was it just his brute strength? Or is it possible that he learned it before he ran off?
Personally, I think he probably learned it before he left. Remember Mufasa showing him how to pounce?
