Jeet Kune Do: Most Common Kick: Roundhouse 2
Low roundhouse: This kick is usually use against the leg but from what, i’ve seen it works for some but for others it failed when their shinbones broke. I recommend that you keep it safe and just roundhouse the groin.
Side roundhouse: This is using the roundhouse sideways like a sidekick for an attacker that comes at you from the side. It’s always good to throw out a fake hand strike to the face before kicking. The best targets are stomach, ribs, and groin.
Rear roundhouse: This is done the same as lead-roundhouse but with more force coming from your back foot. Check the source link.
