Could I mention something? nice tutorial!!!
The step off/feet placement of the kong is quite important for getting your kongs farther when you land.
2 types of feet placement
1 is the punch, which is mainly used to kong on a obstacle quite tall for your comfort level for kongs.
A "punch" to all beginners to Parkour with no gymnastic expieriece, is where you have your feet together, and you "punch" the ground. The downside to this is you lose some momentum. What you do is when you run up, do a little skip with whatever leg you choose, punch, and then go into the long.
2 is what I call, spread foot. This foot placement is what he did in the video. When your in the spread foot placementwhat you want to do is place your hands on the obstacle and right when you do that, bring your back leg up while Pushing forward with your hands a little. then bring your other leg up to meet the back leg, while then applying more push to the hands.
You should then be in sortve a handstand position but your body should be in a 140-160 degree position.
You can use this kong as a starter to Double kongs, far kong precisions, and basically any kong where you want to travel father. Downside is your hips won't be able to meet tall objects you want to kong.
All these foot placements require conditioning if you want to go farther, or kong a farther object.
Hope I have helped
