Groin Kick Technique

The first thing is stick your hip forward then lift your knee up then the rest of the leg comes up with a quick snap.  This technique should be practiced on partners who have different height.  

Jumping Attackers

There's no need to jump for any attacks that would be silly and anyone can see it coming and counter you or just move backwards.  The one thing you can look for is the beginning of the jump when they start to come off their feet then you can strike or push them.

Some Random Stuff

When your out try to remember not to wear headphones that stop you from hearing anything else besides the music.  Make sure when your moving on your feet that you have your lower lead-leg in this position / and have your knees slightly bent.  When your in a bear-hug and you headbutt you want to jab with your head instead of hammering with it.
