The Jerk will come.
Make sure you stand upright and tall, knees locked out, lean a tiny bit backwards so you can nearly feel your toes coming off the floor.
-Shoulders, hips and heels should be inline,
-knees go out, body is upright
-drive off your heels
-back leg doesn't go too far backwards
-front foot should move futher forwards.
Most important thing is driving the bar up properly AND GETTING YOUR HIPS UNDER THE BAR. You can recover the Jerks this way, if it's in front it will more then likely fall to the ground at limit.
FS at least 2-3x a week. Get a really strong FS. It doesn't take much time to hammer a top set of FS for a triple 2x a week if your strong, e.g. 180+ for a triple. If you can't do that I'd squat 2-3x a week to get it up. Even then I'd work the squats 2x a week.
Hammer all the bar work and dynamic stretching.
