I might have either missed something when looking through the guides, or I'm that much of a fluffbrain, but how do you raise the Training Experience of male cubs/adolescents besides the Cub Training page in Explore?

I have only had one male cub so far and he's stuck at 15%

Any tips would be appreciated!

*Edit: Thanks for the help you guys, but I haven't been able to send my male adol on patrols since he is the only other male in the pride besides the king. And it won't let me send him out unless I have an adult sub male for him to tag along with. I honestly wish there was an easier way to train him, like how the females can join in on hunts.
