They may appear to be playing with each other, but there is a deeper meaning behind all of the commotion.
These lion cubs are learning how to use their muscles. They learn which directions their bodies can twist and bend and, of course, which directions they cannot! This "fun training" is all for the future, when they are hunting evasive impala or powerful buffalo, "Speed," "Agility," and "Reaction Time" could mean the difference between having a meal or going hungry! And they learn this at a young age to give them an "edge" when they get older!
